css columns / flexbox with no gaps between items - javascript

I need to get rid of gaps between elements in my column layout. I can use the latest css3 as the site is targeted at modern browsers/devices but I need to avoid a javascript solution such that the page as delivered from the server doesn't need to be re-rendered based on the width of the client.
Using flexbox, css columns, and other tricks I need to coax a pinterest-like layout. (Pinterest uses javascript and absolute positioning for their layout, it doesn't even render with js turned off.) The site has boxes with a known width but variable height. The number of columns needs to vary based on browser width. (I can do this via media queries if I know what css attribute to change.) Here's what this looks like: via
Also note that I can't just increase the height of the containers to fill the empty space. I want to bring the item below it UP, not make all the heights match. (So stretching items 1, 3, and 4 in the picture above is NOT what I want.)
Things I've tried:
CSS 3 columns. This looks great, but the items are in the wrong order, with the second item being under the first. If this can be changed to a different order such that they go left-to-right, great!
Flexbox various flexbox configurations, I've tried just about every setting that I was able to change.
Javascript. Yes, I know I can manually create columns and re-render them on resize. I'm looking to avoid an expensive re-render operation that requires a manual balancing of columns and display. I can resort to this for older browsers that don't support a css3 solution. I'm also wanting to avoid manually positioning all of the items. Gross.
I've put a comment link to JSFiddle because I can't put it in here as "links to jsfiddle require code".

check this demo. This is pure css3 masonry effect.

Hope this is helpful to you.

You can achieve it by flexbox:
HTML:
<div class="container">
<div class="item">1</div>
<div class="item">2</div>
<div class="item">3</div>
<div class="item">4</div>
<div class="item">5</div>
<div class="item">6</div>
</div>
CSS:
.container {
max-width: 900px;
height: 470px;
display: flex;
flex-flow: column wrap;
align-items: flex-start;
}
.item {
height: 150px;
}
http://codepen.io/asim-coder/pen/vXzKgg

CSS3: Set the main ul li that holds all 8 drop-down panels to margin: 0 auto;
mainList li {
margin: 0 auto; /*0 giving no margins on the top and bottom of the panels, and auto making the panels use all of the space within the parent, mainList. I hope this helps.*/
}

Well, a little bit late, may be this could be a solution.
I am using flex as it is the only system that can change the order as you want.
The drawbacks of this method is that I need to use some artificial elements to act as separators, and that I need to set a predetermined height on the container
.container {
border: 1px solid black;
width: 90%;
height: 700px;
display: flex;
flex-flow: column wrap;
align-items: flex-start;
}
.item {
height: 150px;
width: 24%;
margin: 2px;
}
.item:nth-child(3n + 1) {
height: 200px;
}
.item:nth-child(3n + 2) {
height: 250px;
}
.item:nth-child(4n) {
background-color: orange;
order: 40;
}
.item:nth-child(4n + 1) {
background-color: green;
order: 10;
}
.item:nth-child(4n + 2) {
background-color: lightblue;
order: 20;
}
.item:nth-child(4n + 3) {
background-color: yellow;
order: 30;
}
.divider {
width: 1px;
background-color: red;
height: 100%;
}
.divider:nth-last-child(3) {
order: 15;
}
.divider:nth-last-child(2) {
order: 25;
}
.divider:nth-last-child(1) {
order: 35;
}
<div class="container">
<div class="item">1</div>
<div class="item">2</div>
<div class="item">3</div>
<div class="item">4</div>
<div class="item">5</div>
<div class="item">6</div>
<div class="item">7</div>
<div class="item">8</div>
<div class="item">9</div>
<div class="divider"></div>
<div class="divider"></div>

Centering horizontally a colum of DIV but keeping 'block' for 'display' (CSS style) [duplicate]

How can I horizontally center a <div> within another <div> using CSS?
<div id="outer">
<div id="inner">Foo foo</div>
</div>
With flexbox it is very easy to style the div horizontally and vertically centered.
#inner {
border: 0.05em solid black;
}
#outer {
border: 0.05em solid red;
width:100%;
display: flex;
justify-content: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
To align the div vertically centered, use the property align-items: center.
Other Solutions
You can apply this CSS to the inner <div>:
#inner {
width: 50%;
margin: 0 auto;
}
Of course, you don't have to set the width to 50%. Any width less than the containing <div> will work. The margin: 0 auto is what does the actual centering.
If you are targeting Internet Explorer 8 (and later), it might be better to have this instead:
#inner {
display: table;
margin: 0 auto;
}
It will make the inner element center horizontally and it works without setting a specific width.
Working example here:
#inner {
display: table;
margin: 0 auto;
border: 1px solid black;
}
#outer {
border: 1px solid red;
width:100%
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
If you don't want to set a fixed width on the inner div you could do something like this:
#outer {
width: 100%;
text-align: center;
}
#inner {
display: inline-block;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
That makes the inner div into an inline element that can be centered with text-align.
The best approaches are with CSS3.
The old box model (deprecated)
display: box and its properties box-pack, box-align, box-orient, box-direction etc. have been replaced by flexbox. While they may still work, they are not recommended to be used in production.
#outer {
width: 100%;
/* Firefox */
display: -moz-box;
-moz-box-pack: center;
-moz-box-align: center;
/* Safari and Chrome */
display: -webkit-box;
-webkit-box-pack: center;
-webkit-box-align: center;
/* W3C */
display: box;
box-pack: center;
box-align: center;
}
#inner {
width: 50%;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
According to your usability you may also use the box-orient, box-flex, box-direction properties.
The modern box model with Flexbox
#outer {
display: flex;
flex-direction: row;
flex-wrap: wrap;
justify-content: center;
align-items: center;
}
Read more about centering the child elements
CSS Box Model Module Level 3
Box model (CSS2)
box-align on MDN
And this explains why the box model is the best approach:
Why is the W3C box model considered better?
#centered {
position: absolute;
left: 50%;
margin-left: -100px;
}
<div id="outer" style="width:200px">
<div id="centered">Foo foo</div>
</div>
Make sure the parent element is positioned, i.e., relative, fixed, absolute, or sticky.
If you don't know the width of your div, you can use transform:translateX(-50%); instead of the negative margin.
With CSS calc(), the code can get even simpler:
.centered {
width: 200px;
position: absolute;
left: calc(50% - 100px);
}
The principle is still the same; put the item in the middle and compensate for the width.
I've created this example to show how to vertically and horizontally align.
The code is basically this:
#outer {
position: relative;
}
and...
#inner {
margin: auto;
position: absolute;
left:0;
right: 0;
top: 0;
bottom: 0;
}
And it will stay in the center even when you resize your screen.
Some posters have mentioned the CSS 3 way to center using display:box.
This syntax is outdated and shouldn't be used anymore. [See also this post].
So just for completeness here is the latest way to center in CSS 3 using the Flexible Box Layout Module.
So if you have simple markup like:
<div class="box">
<div class="item1">A</div>
<div class="item2">B</div>
<div class="item3">C</div>
</div>
...and you want to center your items within the box, here's what you need on the parent element (.box):
.box {
display: flex;
flex-wrap: wrap; /* Optional. only if you want the items to wrap */
justify-content: center; /* For horizontal alignment */
align-items: center; /* For vertical alignment */
}
.box {
display: flex;
flex-wrap: wrap;
/* Optional. only if you want the items to wrap */
justify-content: center;
/* For horizontal alignment */
align-items: center;
/* For vertical alignment */
}
* {
margin: 0;
padding: 0;
}
html,
body {
height: 100%;
}
.box {
height: 200px;
display: flex;
flex-wrap: wrap;
justify-content: center;
align-items: center;
border: 2px solid tomato;
}
.box div {
margin: 0 10px;
width: 100px;
}
.item1 {
height: 50px;
background: pink;
}
.item2 {
background: brown;
height: 100px;
}
.item3 {
height: 150px;
background: orange;
}
<div class="box">
<div class="item1">A</div>
<div class="item2">B</div>
<div class="item3">C</div>
</div>
If you need to support older browsers which use older syntax for flexbox here's a good place to look.
If you don't want to set a fixed width and don't want the extra margin, add display: inline-block to your element.
You can use:
#element {
display: table;
margin: 0 auto;
}
Centering a div of unknown height and width
Horizontally and vertically. It works with reasonably modern browsers (Firefox, Safari/WebKit, Chrome, Internet & Explorer & 10, Opera, etc.)
.content {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
<div class="content">This works with any content</div>
Tinker with it further on Codepen or on JSBin.
Set the width and set margin-left and margin-right to auto. That's for horizontal only, though. If you want both ways, you'd just do it both ways. Don't be afraid to experiment; it's not like you'll break anything.
It cannot be centered if you don't give it a width. Otherwise, it will take, by default, the whole horizontal space.
CSS 3's box-align property
#outer {
width: 100%;
height: 100%;
display: box;
box-orient: horizontal;
box-pack: center;
box-align: center;
}
The way I usually do it is using absolute position:
#inner{
left: 0;
right: 0;
margin-left: auto;
margin-right: auto;
position: absolute;
}
The outer div doesn't need any extra properties for this to work.
I recently had to center a "hidden" div (i.e., display:none;) that had a tabled form within it that needed to be centered on the page. I wrote the following jQuery code to display the hidden div and then update the CSS content to the automatic generated width of the table and change the margin to center it. (The display toggle is triggered by clicking on a link, but this code wasn't necessary to display.)
NOTE: I'm sharing this code, because Google brought me to this Stack Overflow solution and everything would have worked except that hidden elements don't have any width and can't be resized/centered until after they are displayed.
$(function(){
$('#inner').show().width($('#innerTable').width()).css('margin','0 auto');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="inner" style="display:none;">
<form action="">
<table id="innerTable">
<tr><td>Name:</td><td><input type="text"></td></tr>
<tr><td>Email:</td><td><input type="text"></td></tr>
<tr><td>Email:</td><td><input type="submit"></td></tr>
</table>
</form>
</div>
For Firefox and Chrome:
<div style="width:100%;">
<div style="width: 50%; margin: 0px auto;">Text</div>
</div>
For Internet Explorer, Firefox, and Chrome:
<div style="width:100%; text-align:center;">
<div style="width: 50%; margin: 0px auto; text-align:left;">Text</div>
</div>
The text-align: property is optional for modern browsers, but it is necessary in Internet Explorer Quirks Mode for legacy browsers support.
Use:
#outerDiv {
width: 500px;
}
#innerDiv {
width: 200px;
margin: 0 auto;
}
<div id="outerDiv">
<div id="innerDiv">Inner Content</div>
</div>
Another solution for this without having to set a width for one of the elements is using the CSS 3 transform attribute.
#outer {
position: relative;
}
#inner {
position: absolute;
left: 50%;
transform: translateX(-50%);
}
The trick is that translateX(-50%) sets the #inner element 50 percent to the left of its own width. You can use the same trick for vertical alignment.
Here's a Fiddle showing horizontal and vertical alignment.
More information is on Mozilla Developer Network.
Chris Coyier who wrote an excellent post on 'Centering in the Unknown' on his blog. It's a roundup of multiple solutions. I posted one that isn't posted in this question. It has more browser support than the Flexbox solution, and you're not using display: table; which could break other things.
/* This parent can be any width and height */
.outer {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.outer:before {
content: '.';
display: inline-block;
height: 100%;
vertical-align: middle;
width: 0;
overflow: hidden;
}
/* The element to be centered, can
also be of any width and height */
.inner {
display: inline-block;
vertical-align: middle;
width: 300px;
}
I recently found an approach:
#outer {
position: absolute;
left: 50%;
}
#inner {
position: relative;
left: -50%;
}
Both elements must be the same width to function correctly.
For example, see this link and the snippet below:
div#outer {
height: 120px;
background-color: red;
}
div#inner {
width: 50%;
height: 100%;
background-color: green;
margin: 0 auto;
text-align: center; /* For text alignment to center horizontally. */
line-height: 120px; /* For text alignment to center vertically. */
}
<div id="outer" style="width:100%;">
<div id="inner">Foo foo</div>
</div>
If you have a lot of children under a parent, so your CSS content must be like this example on fiddle.
The HTML content look likes this:
<div id="outer" style="width:100%;">
<div class="inner"> Foo Text </div>
<div class="inner"> Foo Text </div>
<div class="inner"> Foo Text </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> Foo Text </div>
</div>
Then see this example on fiddle.
Centering only horizontally
In my experience, the best way to center a box horizontally is to apply the following properties:
The container:
should have text-align: center;
The content box:
should have display: inline-block;
Demo:
.container {
width: 100%;
height: 120px;
background: #CCC;
text-align: center;
}
.centered-content {
display: inline-block;
background: #FFF;
padding: 20px;
border: 1px solid #000;
}
<div class="container">
<div class="centered-content">
Center this!
</div>
</div>

Centering both horizontally & vertically
In my experience, the best way to center a box both vertically and horizontally is to use an additional container and apply the following properties:
The outer container:
should have display: table;
The inner container:
should have display: table-cell;
should have vertical-align: middle;
should have text-align: center;
The content box:
should have display: inline-block;
Demo:
.outer-container {
display: table;
width: 100%;
height: 120px;
background: #CCC;
}
.inner-container {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered-content {
display: inline-block;
background: #FFF;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Center this!
</div>
</div>
</div>

Flexbox
display: flex behaves like a block element and lays out its content according to the flexbox model. It works with justify-content: center.
Please note: Flexbox is compatible all browsers exept Internet Explorer. See display: flex not working on Internet Explorer for a complete and up to date list of browsers compatibility.
#inner {
display: inline-block;
}
#outer {
display: flex;
justify-content: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Text-align: center
Applying text-align: center the inline contents are centered within the line box. However since the inner div has by default width: 100% you have to set a specific width or use one of the following:
display: block
display: inline
display: inline-block
#inner {
display: inline-block;
}
#outer {
text-align: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Margin: 0 auto
Using margin: 0 auto is another option and it is more suitable for older browsers compatibility. It works together with display: table.
#inner {
display: table;
margin: 0 auto;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Transform
transform: translate lets you modify the coordinate space of the CSS visual formatting model. Using it, elements can be translated, rotated, scaled, and skewed. To center horizontally it require position: absolute and left: 50%.
#inner {
position: absolute;
left: 50%;
transform: translate(-50%, 0%);
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
<center> (Deprecated)
The tag <center> is the HTML alternative to text-align: center. It works on older browsers and most of the new ones but it is not considered a good practice since this feature is obsolete and has been removed from the Web standards.
#inner {
display: inline-block;
}
<div id="outer">
<center>
<div id="inner">Foo foo</div>
</center>
</div>
This method also works just fine:
div.container {
display: flex;
justify-content: center; /* For horizontal alignment */
align-items: center; /* For vertical alignment */
}
For the inner <div>, the only condition is that its height and width must not be larger than the ones of its container.
The easiest way:
#outer {
width: 100%;
text-align: center;
}
#inner {
margin: auto;
width: 200px;
}
<div id="outer">
<div id="inner">Blabla</div>
</div>
Flex have more than 97% browser support coverage and might be the best way to solve these kind of problems within few lines:
#outer {
display: flex;
justify-content: center;
}
If width of the content is unknown you can use the following method. Suppose we have these two elements:
.outer -- full width
.inner -- no width set (but a max-width could be specified)
Suppose the computed width of the elements are 1000 pixels and 300 pixels respectively. Proceed as follows:
Wrap .inner inside .center-helper
Make .center-helper an inline block; it becomes the same size as .inner making it 300 pixels wide.
Push .center-helper 50% right relative to its parent; this places its left at 500 pixels wrt. outer.
Push .inner 50% left relative to its parent; this places its left at -150 pixels wrt. center helper which means its left is at 500 - 150 = 350 pixels wrt. outer.
Set overflow on .outer to hidden to prevent horizontal scrollbar.
Demo:
body {
font: medium sans-serif;
}
.outer {
overflow: hidden;
background-color: papayawhip;
}
.center-helper {
display: inline-block;
position: relative;
left: 50%;
background-color: burlywood;
}
.inner {
display: inline-block;
position: relative;
left: -50%;
background-color: wheat;
}
<div class="outer">
<div class="center-helper">
<div class="inner">
<h1>A div with no defined width</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.<br>
Duis condimentum sem non turpis consectetur blandit.<br>
Donec dictum risus id orci ornare tempor.<br>
Proin pharetra augue a lorem elementum molestie.<br>
Nunc nec justo sit amet nisi tempor viverra sit amet a ipsum.</p>
</div>
</div>
</div>
You can do something like this
#container {
display: table;
width: <width of your container>;
height: <height of your container>;
}
#inner {
width: <width of your center div>;
display: table-cell;
margin: 0 auto;
text-align: center;
vertical-align: middle;
}
This will also align the #inner vertically. If you don't want to, remove the display and vertical-align properties;
Here is what you want in the shortest way.
JSFIDDLE
#outer {
margin - top: 100 px;
height: 500 px; /* you can set whatever you want */
border: 1 px solid# ccc;
}
#inner {
border: 1 px solid# f00;
position: relative;
top: 50 % ;
transform: translateY(-50 % );
}
You can use display: flex for your outer div and to horizontally center you have to add justify-content: center
#outer{
display: flex;
justify-content: center;
}
or you can visit w3schools - CSS flex Property for more ideas.
Well, I managed to find a solution that maybe will fit all situations, but uses JavaScript:
Here's the structure:
<div class="container">
<div class="content">Your content goes here!</div>
<div class="content">Your content goes here!</div>
<div class="content">Your content goes here!</div>
</div>
And here's the JavaScript snippet:
$(document).ready(function() {
$('.container .content').each( function() {
container = $(this).closest('.container');
content = $(this);
containerHeight = container.height();
contentHeight = content.height();
margin = (containerHeight - contentHeight) / 2;
content.css('margin-top', margin);
})
});
If you want to use it in a responsive approach, you can add the following:
$(window).resize(function() {
$('.container .content').each( function() {
container = $(this).closest('.container');
content = $(this);
containerHeight = container.height();
contentHeight = content.height();
margin = (containerHeight - contentHeight) / 2;
content.css('margin-top', margin);
})
});
One option existed that I found:
Everybody says to use:
margin: auto 0;
But there is another option. Set this property for the parent div. It
works perfectly anytime:
text-align: center;
And see, child go center.
And finally CSS for you:
#outer{
text-align: center;
display: block; /* Or inline-block - base on your need */
}
#inner
{
position: relative;
margin: 0 auto; /* It is good to be */
}

With flexbox it is very easy to style the div horizontally and vertically centered.
#inner {
border: 0.05em solid black;
}
#outer {
border: 0.05em solid red;
width:100%;
display: flex;
justify-content: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
To align the div vertically centered, use the property align-items: center.
Other Solutions
You can apply this CSS to the inner <div>:
#inner {
width: 50%;
margin: 0 auto;
}
Of course, you don't have to set the width to 50%. Any width less than the containing <div> will work. The margin: 0 auto is what does the actual centering.
If you are targeting Internet Explorer 8 (and later), it might be better to have this instead:
#inner {
display: table;
margin: 0 auto;
}
It will make the inner element center horizontally and it works without setting a specific width.
Working example here:
#inner {
display: table;
margin: 0 auto;
border: 1px solid black;
}
#outer {
border: 1px solid red;
width:100%
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
If you don't want to set a fixed width on the inner div you could do something like this:
#outer {
width: 100%;
text-align: center;
}
#inner {
display: inline-block;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
That makes the inner div into an inline element that can be centered with text-align.
The best approaches are with CSS3.
The old box model (deprecated)
display: box and its properties box-pack, box-align, box-orient, box-direction etc. have been replaced by flexbox. While they may still work, they are not recommended to be used in production.
#outer {
width: 100%;
/* Firefox */
display: -moz-box;
-moz-box-pack: center;
-moz-box-align: center;
/* Safari and Chrome */
display: -webkit-box;
-webkit-box-pack: center;
-webkit-box-align: center;
/* W3C */
display: box;
box-pack: center;
box-align: center;
}
#inner {
width: 50%;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
According to your usability you may also use the box-orient, box-flex, box-direction properties.

flex-wrap: wrap;
justify-content: center;

And this explains why the box model is the best approach:
Why is the W3C box model considered better?
#centered {
position: absolute;
left: 50%;
margin-left: -100px;
}
<div id="outer" style="width:200px">
<div id="centered">Foo foo</div>
</div>
Make sure the parent element is positioned, i.e., relative, fixed, absolute, or sticky.
If you don't know the width of your div, you can use transform:translateX(-50%); instead of the negative margin.
With CSS calc(), the code can get even simpler:
.centered {
width: 200px;
position: absolute;
left: calc(50% - 100px);
}
The principle is still the same; put the item in the middle and compensate for the width.
I've created this example to show how to vertically and horizontally align.
The code is basically this:
#outer {
position: relative;
}
and...
#inner {
margin: auto;
position: absolute;
left:0;
right: 0;
top: 0;
bottom: 0;
}
And it will stay in the center even when you resize your screen.
Some posters have mentioned the CSS 3 way to center using display:box.
This syntax is outdated and shouldn't be used anymore. [See also this post].
So just for completeness here is the latest way to center in CSS 3 using the Flexible Box Layout Module.
So if you have simple markup like:
<div class="box">
<div class="item1">A</div>
<div class="item2">B</div>
<div class="item3">C</div>
</div>
...and you want to center your items within the box, here's what you need on the parent element (.box):
.box {
display: flex;
flex-wrap: wrap; /* Optional. only if you want the items to wrap */
justify-content: center; /* For horizontal alignment */
align-items: center; /* For vertical alignment */
}
.box {
display: flex;
flex-wrap: wrap;
/* Optional. only if you want the items to wrap */
justify-content: center;
/* For horizontal alignment */
align-items: center;
/* For vertical alignment */
}
* {
margin: 0;
padding: 0;
}
html,
body {
height: 100%;
}
.box {
height: 200px;
display: flex;
flex-wrap: wrap;
justify-content: center;
align-items: center;
border: 2px solid tomato;
}
.box div {
margin: 0 10px;

}
.item1 {
height: 50px;

}
.item2 {

}
.item3 {
height: 150px;
background: orange;
}
<div class="box">
<div class="item1">A</div>
<div class="item2">B</div>
<div class="item3">C</div>
</div>
If you need to support older browsers which use older syntax for flexbox here's a good place to look.
If you don't want to set a fixed width and don't want the extra margin, add display: inline-block to your element.
You can use:
#element {
display: table;
margin: 0 auto;
}
Centering a div of unknown height and width
Horizontally and vertically. It works with reasonably modern browsers (Firefox, Safari/WebKit, Chrome, Internet & Explorer & 10, Opera, etc.)
.content {
position: absolute;
left: 50%;
top: 50%;
transform: translate(-50%, -50%);
}
<div class="content">This works with any content</div>
Tinker with it further on Codepen or on JSBin.
Set the width and set margin-left and margin-right to auto. That's for horizontal only, though. If you want both ways, you'd just do it both ways. Don't be afraid to experiment; it's not like you'll break anything.
It cannot be centered if you don't give it a width. Otherwise, it will take, by default, the whole horizontal space.
CSS 3's box-align property
#outer {
width: 100%;
height: 100%;
display: box;
box-orient: horizontal;
box-pack: center;
box-align: center;
}
The way I usually do it is using absolute position:
#inner{
left: 0;
right: 0;
margin-left: auto;
margin-right: auto;
position: absolute;
}
The outer div doesn't need any extra properties for this to work.
I recently had to center a "hidden" div (i.e., display:none;) that had a tabled form within it that needed to be centered on the page. I wrote the following jQuery code to display the hidden div and then update the CSS content to the automatic generated width of the table and change the margin to center it. (The display toggle is triggered by clicking on a link, but this code wasn't necessary to display.)
NOTE: I'm sharing this code, because Google brought me to this Stack Overflow solution and everything would have worked except that hidden elements don't have any width and can't be resized/centered until after they are displayed.
$(function(){
$('#inner').show().width($('#innerTable').width()).css('margin','0 auto');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="inner" style="display:none;">
<form action="">
<table id="innerTable">
<tr><td>Name:</td><td><input type="text"></td></tr>
<tr><td>Email:</td><td><input type="text"></td></tr>
<tr><td>Email:</td><td><input type="submit"></td></tr>
</table>
</form>
</div>
For Firefox and Chrome:
<div style="width:100%;">
<div style="width: 50%; margin: 0px auto;">Text</div>
</div>
For Internet Explorer, Firefox, and Chrome:
<div style="width:100%; text-align:center;">
<div style="width: 50%; margin: 0px auto; text-align:left;">Text</div>
</div>
The text-align: property is optional for modern browsers, but it is necessary in Internet Explorer Quirks Mode for legacy browsers support.
Use:
#outerDiv {
width: 500px;
}
#innerDiv {
width: 200px;
margin: 0 auto;
}
<div id="outerDiv">
<div id="innerDiv">Inner Content</div>
</div>
Another solution for this without having to set a width for one of the elements is using the CSS 3 transform attribute.
#outer {
position: relative;
}
#inner {
position: absolute;
left: 50%;
transform: translateX(-50%);
}
The trick is that translateX(-50%) sets the #inner element 50 percent to the left of its own width. You can use the same trick for vertical alignment.
Here's a Fiddle showing horizontal and vertical alignment.
More information is on Mozilla Developer Network.
Chris Coyier who wrote an excellent post on 'Centering in the Unknown' on his blog. It's a roundup of multiple solutions. I posted one that isn't posted in this question. It has more browser support than the Flexbox solution, and you're not using display: table; which could break other things.
/* This parent can be any width and height */
.outer {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.outer:before {
content: '.';
display: inline-block;
height: 100%;
vertical-align: middle;
width: 0;
overflow: hidden;
}
/* The element to be centered, can
also be of any width and height */
.inner {
display: inline-block;
vertical-align: middle;
width: 300px;
}
I recently found an approach:
#outer {
position: absolute;
left: 50%;
}
#inner {
position: relative;
left: -50%;
}
Both elements must be the same width to function correctly.
For example, see this link and the snippet below:
div#outer {
height: 120px;
background-color: red;
}
div#inner {
width: 50%;
height: 100%;
background-color: green;
margin: 0 auto;
text-align: center; /* For text alignment to center horizontally. */
line-height: 120px; /* For text alignment to center vertically. */
}
<div id="outer" style="width:100%;">
<div id="inner">Foo foo</div>
</div>
If you have a lot of children under a parent, so your CSS content must be like this example on fiddle.
The HTML content look likes this:
<div id="outer" style="width:100%;">
<div class="inner"> Foo Text </div>
<div class="inner"> Foo Text </div>
<div class="inner"> Foo Text </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> Foo Text </div>
</div>
Then see this example on fiddle.
Centering only horizontally
In my experience, the best way to center a box horizontally is to apply the following properties:
The container:
should have text-align: center;
The content box:
should have display: inline-block;
Demo:
.container {
width: 100%;
height: 120px;
background: #CCC;
text-align: center;
}
.centered-content {
display: inline-block;
background: #FFF;
padding: 20px;
border: 1px solid #000;
}
<div class="container">
<div class="centered-content">
Center this!
</div>
</div>

Centering both horizontally & vertically
In my experience, the best way to center a box both vertically and horizontally is to use an additional container and apply the following properties:
The outer container:
should have display: table;
The inner container:
should have display: table-cell;
should have vertical-align: middle;
should have text-align: center;
The content box:
should have display: inline-block;
Demo:
.outer-container {
display: table;
width: 100%;
height: 120px;
background: #CCC;
}
.inner-container {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered-content {
display: inline-block;
background: #FFF;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Center this!
</div>
</div>
</div>

Flexbox
display: flex behaves like a block element and lays out its content according to the flexbox model. It works with justify-content: center.
Please note: Flexbox is compatible all browsers exept Internet Explorer. See display: flex not working on Internet Explorer for a complete and up to date list of browsers compatibility.
#inner {
display: inline-block;
}
#outer {
display: flex;
justify-content: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Text-align: center
Applying text-align: center the inline contents are centered within the line box. However since the inner div has by default width: 100% you have to set a specific width or use one of the following:
display: block
display: inline
display: inline-block
#inner {
display: inline-block;
}
#outer {
text-align: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Margin: 0 auto
Using margin: 0 auto is another option and it is more suitable for older browsers compatibility. It works together with display: table.
#inner {
display: table;
margin: 0 auto;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Transform
transform: translate lets you modify the coordinate space of the CSS visual formatting model. Using it, elements can be translated, rotated, scaled, and skewed. To center horizontally it require position: absolute and left: 50%.
#inner {
position: absolute;
left: 50%;
transform: translate(-50%, 0%);
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
<center> (Deprecated)
The tag <center> is the HTML alternative to text-align: center. It works on older browsers and most of the new ones but it is not considered a good practice since this feature is obsolete and has been removed from the Web standards.
#inner {
display: inline-block;
}
<div id="outer">
<center>
<div id="inner">Foo foo</div>
</center>
</div>
This method also works just fine:
div.container {
display: flex;
justify-content: center; /* For horizontal alignment */
align-items: center; /* For vertical alignment */
}
For the inner <div>, the only condition is that its height and width must not be larger than the ones of its container.
The easiest way:
#outer {
width: 100%;
text-align: center;
}
#inner {
margin: auto;
width: 200px;
}
<div id="outer">
<div id="inner">Blabla</div>
</div>
Flex have more than 97% browser support coverage and might be the best way to solve these kind of problems within few lines:
#outer {
display: flex;
justify-content: center;
}
If width of the content is unknown you can use the following method. Suppose we have these two elements:
.outer -- full width
.inner -- no width set (but a max-width could be specified)
Suppose the computed width of the elements are 1000 pixels and 300 pixels respectively. Proceed as follows:
Wrap .inner inside .center-helper
Make .center-helper an inline block; it becomes the same size as .inner making it 300 pixels wide.
Push .center-helper 50% right relative to its parent; this places its left at 500 pixels wrt. outer.
Push .inner 50% left relative to its parent; this places its left at -150 pixels wrt. center helper which means its left is at 500 - 150 = 350 pixels wrt. outer.
Set overflow on .outer to hidden to prevent horizontal scrollbar.
Demo:
body {
font: medium sans-serif;
}
.outer {
overflow: hidden;
background-color: papayawhip;
}
.center-helper {
display: inline-block;
position: relative;
left: 50%;
background-color: burlywood;
}
.inner {
display: inline-block;
position: relative;
left: -50%;
background-color: wheat;
}
<div class="outer">
<div class="center-helper">
<div class="inner">
<h1>A div with no defined width</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.<br>
Duis condimentum sem non turpis consectetur blandit.<br>
Donec dictum risus id orci ornare tempor.<br>
Proin pharetra augue a lorem elementum molestie.<br>
Nunc nec justo sit amet nisi tempor viverra sit amet a ipsum.</p>
</div>
</div>
</div>
You can do something like this
#container {
display: table;
width: <width of your container>;
height: <height of your container>;
}
#inner {
width: <width of your center div>;
display: table-cell;
margin: 0 auto;
text-align: center;
vertical-align: middle;
}
This will also align the #inner vertically. If you don't want to, remove the display and vertical-align properties;
Here is what you want in the shortest way.
JSFIDDLE
#outer {
margin - top: 100 px;
height: 500 px; /* you can set whatever you want */
border: 1 px solid# ccc;
}
#inner {
border: 1 px solid# f00;
position: relative;
top: 50 % ;
transform: translateY(-50 % );
}
You can use display: flex for your outer div and to horizontally center you have to add justify-content: center
#outer{
display: flex;
justify-content: center;
}
or you can visit w3schools - CSS flex Property for more ideas.
Well, I managed to find a solution that maybe will fit all situations, but uses JavaScript:
Here's the structure:
<div class="container">
<div class="content">Your content goes here!</div>
<div class="content">Your content goes here!</div>
<div class="content">Your content goes here!</div>
</div>
And here's the JavaScript snippet:
$(document).ready(function() {
$('.container .content').each( function() {
container = $(this).closest('.container');
content = $(this);
containerHeight = container.height();
contentHeight = content.height();
margin = (containerHeight - contentHeight) / 2;
content.css('margin-top', margin);
})
});
If you want to use it in a responsive approach, you can add the following:
$(window).resize(function() {
$('.container .content').each( function() {
container = $(this).closest('.container');
content = $(this);
containerHeight = container.height();
contentHeight = content.height();
margin = (containerHeight - contentHeight) / 2;
content.css('margin-top', margin);
})
});
One option existed that I found:
Everybody says to use:
margin: auto 0;
But there is another option. Set this property for the parent div. It
works perfectly anytime:
text-align: center;
And see, child go center.
And finally CSS for you:
#outer{
text-align: center;
display: block; /* Or inline-block - base on your need */
}
#inner
{
position: relative;
margin: 0 auto; /* It is good to be */
}

I have an element centered in the screen and I want another element to be centered just right below the first element [duplicate]

NOTE: I'm sharing this code, because Google brought me to this Stack Overflow solution and everything would have worked except that hidden elements don't have any width and can't be resized/centered until after they are displayed.
$(function(){
$('#inner').show().width($('#innerTable').width()).css('margin','0 auto');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="inner" style="display:none;">
<form action="">
<table id="innerTable">
<tr><td>Name:</td><td><input type="text"></td></tr>
<tr><td>Email:</td><td><input type="text"></td></tr>
<tr><td>Email:</td><td><input type="submit"></td></tr>
</table>
</form>
</div>
For Firefox and Chrome:
<div style="width:100%;">
<div style="width: 50%; margin: 0px auto;">Text</div>
</div>
For Internet Explorer, Firefox, and Chrome:
<div style="width:100%; text-align:center;">
<div style="width: 50%; margin: 0px auto; text-align:left;">Text</div>
</div>
The text-align: property is optional for modern browsers, but it is necessary in Internet Explorer Quirks Mode for legacy browsers support.
Use:
#outerDiv {
width: 500px;
}
#innerDiv {
width: 200px;
margin: 0 auto;
}
<div id="outerDiv">
<div id="innerDiv">Inner Content</div>
</div>
Another solution for this without having to set a width for one of the elements is using the CSS 3 transform attribute.
#outer {
position: relative;
}
#inner {
position: absolute;
left: 50%;
transform: translateX(-50%);
}
The trick is that translateX(-50%) sets the #inner element 50 percent to the left of its own width. You can use the same trick for vertical alignment.
Here's a Fiddle showing horizontal and vertical alignment.
More information is on Mozilla Developer Network.
Chris Coyier who wrote an excellent post on 'Centering in the Unknown' on his blog. It's a roundup of multiple solutions. I posted one that isn't posted in this question. It has more browser support than the Flexbox solution, and you're not using display: table; which could break other things.
/* This parent can be any width and height */
.outer {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.outer:before {
content: '.';
display: inline-block;
height: 100%;
vertical-align: middle;
width: 0;
overflow: hidden;
}
/* The element to be centered, can
also be of any width and height */
.inner {
display: inline-block;
vertical-align: middle;
width: 300px;
}
I recently found an approach:
#outer {
position: absolute;
left: 50%;
}
#inner {
position: relative;
left: -50%;
}
Both elements must be the same width to function correctly.
For example, see this link and the snippet below:
div#outer {
height: 120px;
background-color: red;
}
div#inner {
width: 50%;
height: 100%;
background-color: green;
margin: 0 auto;
text-align: center; /* For text alignment to center horizontally. */
line-height: 120px; /* For text alignment to center vertically. */
}
<div id="outer" style="width:100%;">
<div id="inner">Foo foo</div>
</div>
If you have a lot of children under a parent, so your CSS content must be like this example on fiddle.
The HTML content look likes this:
<div id="outer" style="width:100%;">
<div class="inner"> Foo Text </div>
<div class="inner"> Foo Text </div>
<div class="inner"> Foo Text </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> </div>
<div class="inner"> Foo Text </div>
</div>
Then see this example on fiddle.
Centering only horizontally
In my experience, the best way to center a box horizontally is to apply the following properties:
The container:
should have text-align: center;
The content box:
should have display: inline-block;
Demo:
.container {
width: 100%;
height: 120px;
background: #CCC;
text-align: center;
}
.centered-content {
display: inline-block;
background: #FFF;
padding: 20px;
border: 1px solid #000;
}
<div class="container">
<div class="centered-content">
Center this!
</div>
</div>

Centering both horizontally & vertically
In my experience, the best way to center a box both vertically and horizontally is to use an additional container and apply the following properties:
The outer container:
should have display: table;
The inner container:
should have display: table-cell;
should have vertical-align: middle;
should have text-align: center;
The content box:
should have display: inline-block;
Demo:
.outer-container {
display: table;
width: 100%;
height: 120px;
background: #CCC;
}
.inner-container {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered-content {
display: inline-block;
background: #FFF;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Center this!
</div>
</div>
</div>

Flexbox
display: flex behaves like a block element and lays out its content according to the flexbox model. It works with justify-content: center.
Please note: Flexbox is compatible all browsers exept Internet Explorer. See display: flex not working on Internet Explorer for a complete and up to date list of browsers compatibility.
#inner {
display: inline-block;
}
#outer {
display: flex;
justify-content: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Text-align: center
Applying text-align: center the inline contents are centered within the line box. However since the inner div has by default width: 100% you have to set a specific width or use one of the following:
display: block
display: inline
display: inline-block
#inner {
display: inline-block;
}
#outer {
text-align: center;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Margin: 0 auto
Using margin: 0 auto is another option and it is more suitable for older browsers compatibility. It works together with display: table.
#inner {
display: table;
margin: 0 auto;
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
Transform
transform: translate lets you modify the coordinate space of the CSS visual formatting model. Using it, elements can be translated, rotated, scaled, and skewed. To center horizontally it require position: absolute and left: 50%.
#inner {
position: absolute;
left: 50%;
transform: translate(-50%, 0%);
}
<div id="outer">
<div id="inner">Foo foo</div>
</div>
<center> (Deprecated)
The tag <center> is the HTML alternative to text-align: center. It works on older browsers and most of the new ones but it is not considered a good practice since this feature is obsolete and has been removed from the Web standards.
#inner {
display: inline-block;
}
<div id="outer">
<center>
<div id="inner">Foo foo</div>
</center>
</div>
This method also works just fine:
div.container {
display: flex;
justify-content: center; /* For horizontal alignment */
align-items: center; /* For vertical alignment */
}
For the inner <div>, the only condition is that its height and width must not be larger than the ones of its container.
The easiest way:
#outer {
width: 100%;
text-align: center;
}
#inner {
margin: auto;
width: 200px;
}
<div id="outer">
<div id="inner">Blabla</div>
</div>
Flex have more than 97% browser support coverage and might be the best way to solve these kind of problems within few lines:
#outer {
display: flex;
justify-content: center;
}
If width of the content is unknown you can use the following method. Suppose we have these two elements:
.outer -- full width
.inner -- no width set (but a max-width could be specified)
Suppose the computed width of the elements are 1000 pixels and 300 pixels respectively. Proceed as follows:
Wrap .inner inside .center-helper
Make .center-helper an inline block; it becomes the same size as .inner making it 300 pixels wide.
Push .center-helper 50% right relative to its parent; this places its left at 500 pixels wrt. outer.
Push .inner 50% left relative to its parent; this places its left at -150 pixels wrt. center helper which means its left is at 500 - 150 = 350 pixels wrt. outer.
Set overflow on .outer to hidden to prevent horizontal scrollbar.
Demo:
body {
font: medium sans-serif;
}
.outer {
overflow: hidden;
background-color: papayawhip;
}
.center-helper {
display: inline-block;
position: relative;
left: 50%;
background-color: burlywood;
}
.inner {
display: inline-block;
position: relative;
left: -50%;
background-color: wheat;
}
<div class="outer">
<div class="center-helper">
<div class="inner">
<h1>A div with no defined width</h1>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.<br>
Duis condimentum sem non turpis consectetur blandit.<br>
Donec dictum risus id orci ornare tempor.<br>
Proin pharetra augue a lorem elementum molestie.<br>
Nunc nec justo sit amet nisi tempor viverra sit amet a ipsum.</p>
</div>
</div>
</div>
You can do something like this
#container {
display: table;
width: <width of your container>;
height: <height of your container>;
}
#inner {
width: <width of your center div>;
display: table-cell;
margin: 0 auto;
text-align: center;
vertical-align: middle;
}
This will also align the #inner vertically. If you don't want to, remove the display and vertical-align properties;
Here is what you want in the shortest way.
JSFIDDLE
#outer {
margin - top: 100 px;
height: 500 px; /* you can set whatever you want */
border: 1 px solid# ccc;
}
#inner {
border: 1 px solid# f00;
position: relative;
top: 50 % ;
transform: translateY(-50 % );
}
You can use display: flex for your outer div and to horizontally center you have to add justify-content: center
#outer{
display: flex;
justify-content: center;
}
or you can visit w3schools - CSS flex Property for more ideas.
Well, I managed to find a solution that maybe will fit all situations, but uses JavaScript:
Here's the structure:
<div class="container">
<div class="content">Your content goes here!</div>
<div class="content">Your content goes here!</div>
<div class="content">Your content goes here!</div>
</div>
And here's the JavaScript snippet:
$(document).ready(function() {
$('.container .content').each( function() {
container = $(this).closest('.container');
content = $(this);
containerHeight = container.height();
contentHeight = content.height();
margin = (containerHeight - contentHeight) / 2;
content.css('margin-top', margin);
})
});
If you want to use it in a responsive approach, you can add the following:
$(window).resize(function() {
$('.container .content').each( function() {
container = $(this).closest('.container');
content = $(this);
containerHeight = container.height();
contentHeight = content.height();
margin = (containerHeight - contentHeight) / 2;
content.css('margin-top', margin);
})
});
One option existed that I found:
Everybody says to use:
margin: auto 0;
But there is another option. Set this property for the parent div. It
works perfectly anytime:
text-align: center;
And see, child go center.
And finally CSS for you:
#outer{
text-align: center;
display: block; /* Or inline-block - base on your need */
}
#inner
{
position: relative;
margin: 0 auto; /* It is good to be */
}

Height of Element Issue

I have the following code:
.embed-responsive {
position: relative;
display: block;
height: 0;
padding: 0;
overflow: hidden;
}
.resume .resume-title {
font-size: 26px;
font-weight: 700;
margin-top: 20px;
margin-bottom: 20px;
color: #050d18;
}
.resume .resume-item {
position: relative;
text-align: center;
}
.add {
padding: 0;
}
#media all and (max-width: 500px) {
.embed-responsive {
height: auto;
}
}
<section id="resume" class="resume">
<div class="container">
<div class="section-title">
<h2>Resumè
</h2>
</div>
<div class="resume-item">
<iframe src="https://drive.google.com/file/d/1QQ3lCOVEBd551AuNOA-XA4x6s1I3AaCZ/preview" width="100%" height="1070"></iframe>
</div>
</div>
</section>
So on my end since I have the above code embedded in a website, the output looks like this:
However, when I view the website using a smaller screen, I am getting this output:
The problem is that the "template" (which is the grey part) extends to height: 1070 even on responsive mode. I want the grey part to end after the document with some margin like shown in the very first picture when you view it on a smaller device.
Expected Output:
Larger Screen
Same picture as the very first picture I sent, so no changes here really.
Smaller Screen:
The Blue Line is where the grey part should end, with some margin in between the document and grey part, as there is at the top. Any suggestions on how I can accomplish this?
I believe something like this:
made a class for the iframe, for the media query I put 140vw
why 140vw? the ratio of an A4 paper is around 1.4 (if you know its some other format... just change the ratio...) this means the height is 1.4 the width, so you can use that instead of a number as you're doing in the default settings.
.embed-responsive {
position: relative;
display: block;
height: 0;
padding: 0;
overflow: hidden;
}
.resume .resume-title {
font-size: 26px;
font-weight: 700;
margin-top: 20px;
margin-bottom: 20px;
color: #050d18;
}
.resume .resume-item {
position: relative;
text-align: center;
}
.add {
padding: 0;
}
.iframe {
height: 1070px;
}
#media all and (max-width: 500px) {
.embed-responsive {
height: auto;
}
.iframe {
height: 140vw;
}
}
<section id="resume" class="resume">
<div class="container">
<div class="section-title">
<h2>Resumè

</div>
<div class="resume-item">
<iframe src="https://drive.google.com/file/d/1QQ3lCOVEBd551AuNOA-XA4x6s1I3AaCZ/preview" width="100%" class="iframe"></iframe>

What's the best way of doing a layout with a searchbar and 4 equal parts in html

I want to make a website that has a space at the top for a searchbar and then 4 divs in a layout like in
this image
I'm using d3 so the idea would be to represent the data in different ways, but I want the divs to adjust to the window, so something like this:
<div id ="main-bar">
</div>
<div id="view">
<div id="topLeft" class="linked-container" >
</div>
<div id="topRight" class="linked-container">
</div>
<div id="botLeft" class="linked-container">
</div>
<div id="botRight" class="linked-container">
</div>
</div>
But I don't know how to make them adjust to the window size.
I'm not pretty good at web developing so I wanted to know how could I do this in a simple way. Any suggestions?
Thanks in advance.
Edit: People are telling me I should not ask for tutorials, which is true. Anyway thanks for your answers, this is what I ended up doing:
#main-bar{top: 0; left:0; width:100%; min-height: 40px; height:10%; position: fixed; background-color: pink; }
#topLeft{top:10%; left:0; background-color: blue;}
#topRight{top:10%; left: 50%; background-color: red;}
#botLeft{top:55%; left:0; background-color: green ;}
#botRight{top:55%; left:50%; background-color: orange;}
I will look into media queries so I can better adjust the searchbar cause the min-height property is not doing what I want.
the best way to align the divs in css is with flexbox.
Check the flexbox guide here.
This should solve your problem: Working JSfiddle

#media all and (min-width: 600px) {
.aside-1, .aside-2 { flex: 1 auto; }
.aside-3, .aside-4 { flex: 1 auto; }
}
#media all and (min-width: 800px) {

.aside-2 { order: 2; }
.aside-3 { order: 3; }
.aside-4 { order: 4; }
}
body {
padding: 2em;
}
You can use the flex property if you want to adjust the size of your divs. Include the below given css in your stylesheet and you are good to go .
#view{
display:flex;
flex-wrap:wrap;
}
.linked-container{
width:50%;
height:200px;
}
You can check the working example in this jsfiddle link .

Note that this uses flex so you'll need to make some fallbacks/tweaks for specific browsers. I'd usually do this with some PostCSS Autoprofixers to help with browser support.
All the best!
