I want to center a div vertically with CSS. I don't want tables or JavaScript, but only pure CSS. I found some solutions, but all of them are missing Internet Explorer 6 support.
<body>
<div>Div to be aligned vertically</div>
</body>
How can I center a div vertically in all major browsers, including Internet Explorer 6?
Below is the best all-around solution I could build to vertically and horizontally center a fixed-width, flexible height content box. It was tested and worked for recent versions of Firefox, Opera, Chrome, and Safari.
.outer {
display: table;
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
margin-left: auto;
margin-right: auto;
width: 400px;
/* Whatever width you want */
}
<div class="outer">
<div class="middle">
<div class="inner">
<h1>The Content</h1>
<p>Once upon a midnight dreary...</p>
</div>
</div>
</div>
View A Working Example With Dynamic Content
I built in some dynamic content to test the flexibility and would love to know if anyone sees any problems with it. It should work well for centered overlays also -- lightbox, pop-up, etc.
The simplest way would be the following three lines of CSS:
1) position: relative;
2) top: 50%;
3) transform: translateY(-50%);
Following is an example:
div.outer-div {
height: 170px;
width: 300px;
background-color: lightgray;
}
div.middle-div {
position: relative;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
}
<div class='outer-div'>
<div class='middle-div'>
Test text
</div>
</div>
One more I can't see on the list:
.Center-Container {
position: relative;
height: 100%;
}
.Absolute-Center {
width: 50%;
height: 50%;
overflow: auto;
margin: auto;
position: absolute;
top: 0; left: 0; bottom: 0; right: 0;
border: solid black;
}
Cross-browser (including Internet Explorer 8 - Internet Explorer 10 without hacks!)
Responsive with percentages and min-/max-
Centered regardless of padding (without box-sizing!)
height must be declared (see Variable Height)
Recommended setting overflow: auto to prevent content spillover (see Overflow)
Source: Absolute Horizontal And Vertical Centering In CSS
Now the Flexbox solution is a very easy way for modern browsers, so I recommend this for you:
.container {
display: flex;
align-items: center;
justify-content: center;
height: 100%;
background: green;
}
body,
html {
height: 100%;
}
<div class="container">
<div>Div to be aligned vertically</div>
</div>
Actually, you need two div's for vertical centering. The div containing the content must have a width and height.
#container {
position: absolute;
top: 50%;
margin-top: -200px;
/* Half of #content height */
left: 0;
width: 100%;
}
#content {
width: 624px;
margin-left: auto;
margin-right: auto;
height: 395px;
border: 1px solid #000000;
}
<div id="container">
<div id="content">
<h1>Centered div</h1>
</div>
</div>
Here is the result.
Edit 2020: only use this if you need to support old browsers like Internet Explorer 8 (which you should refuse to do 😉). If not, use Flexbox.
This is the simplest method I found and I use it all the time
(jsFiddle demo here).

</div>
Support starts with Internet Explorer 8.
After a lot of research I finally found the ultimate solution. It works even for floated elements. View Source
.element {
position: relative;
top: 50%;
transform: translateY(-50%); /* or try 50% */
}
Use the CSS Flexbox align-items property to achieve this.
html, body {
height: 100%;
}
body {
display: flex;
align-items: center;
}
<div>This is centered vertically</div>
To center the div on a page, check the fiddle link.
#vh {
margin: auto;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>
Another option is to use flex box, check the fiddle link.
.vh {
background-color: #ddd;
height: 400px;
align-items: center;
display: flex;
}
.vh > div {
width: 100%;
text-align: center;
vertical-align: middle;
}
<div class="vh">
<div>Div to be aligned vertically</div>
</div>
Another option is to use a CSS 3 transform:
#vh {
position: absolute;
top: 50%;
left: 50%;
/*transform: translateX(-50%) translateY(-50%);*/
transform: translate(-50%, -50%);
}
.box{
border-radius: 15px;
box-shadow: 0 0 8px rgba(0, 0, 0, 0.4);
padding: 25px;
width: 100px;
height: 100px;
background: white;
}
<div id="vh" class="box">Div to be aligned vertically</div>
The easiest solution is below:
.outer-div{
width: 100%;
height: 200px;
display: flex;
border:1px solid #000;
}
.inner-div{
margin: auto;
text-align: center;
border: 1px solid red;
}
<div class="outer-div">
<div class="inner-div">
Hey there!
</div>
</div>
There are multiple ways to achieve this.
Using flex property of CSS.
Solution #1
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>
or by using display: flex; and margin: auto;
Solution #2
.parent {
width: 400px;
height:200px;
background: blue;
display: flex;
}
.child {
width: 75px;
height: 75px;
background: yellow;
margin:auto;
}
<div class="parent">
<div class="child"></div>
</div>
show text center
Solution #3
.parent {
width: 400px;
height: 200px;
background: yellow;
display: flex;
align-items: center;
justify-content:center;
}
<div class="parent">Center</div>
Using percentage(%) height and width.
Solution #4
.parent {
position: absolute;
height:100%;
width:100%;
background: blue;
display: flex;
align-items: center;
justify-content:center;
}
.child {
width: 75px;
height: 75px;
background: yellow;
}
<div class="parent">
<div class="child"></div>
</div>
Unfortunately — but not surprisingly — the solution is more complicated than one would wish it to be. Also unfortunately, you'll need to use additional divs around the div you want vertically centered.
For standards-compliant browsers like Mozilla, Opera, Safari, etc. you need to set the outer div to be displayed as a table and the inner div to be displayed as a table-cell — which can then be vertically centered. For Internet Explorer, you need to position the inner div absolutely within the outer div and then specify the top as 50%. The following pages explain this technique well and provide some code samples too:
Vertical Centering in CSS
Vertical Centering in CSS with Unknown Height (Internet Explorer 7 compatible) (Archived article courtesy of the Wayback Machine)
There is also a technique to do the vertical centering using JavaScript. Vertical alignment of content with JavaScript & CSS demonstrates it.
If someone cares for Internet Explorer 10 (and later) only, use Flexbox:
.parent {
width: 500px;
height: 500px;
background: yellow;
display: -webkit-flex;
display: -ms-flexbox;
display: flex;
-webkit-justify-content: center;
-ms-flex-pack: center;
justify-content: center;
-webkit-align-items: center;
-ms-flex-align: center;
align-items: center;
}
.centered {
width: 100px;
height: 100px;
background: blue;
}
<div class="parent">
<div class="centered"></div>
</div>
Flexbox support: http://caniuse.com/flexbox
A modern way to center an element vertically would be to use flexbox.
You need a parent to decide the height and a child to center.
The example below will center a div to the center within your browser. What's important (in my example) is to set height: 100% to body and html and then min-height: 100% to your container.
body, html {
background: #F5F5F5;
box-sizing: border-box;
height: 100%;
margin: 0;
}
#center_container {
align-items: center;
display: flex;
min-height: 100%;
}
#center {
background: white;
margin: 0 auto;
padding: 10px;
text-align: center;
width: 200px;
}
<div id='center_container'>
<div id='center'>I am center.</div>
</div>
.center {
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%); /* (x, y) => position */
-ms-transform: translate(-50%, -50%); /* IE 9 */
-webkit-transform: translate(-50%, -50%); /* Chrome, Safari, Opera */
}
.vertical {
position: absolute;
top: 50%;
//left: 0;
transform: translate(0, -50%); /* (x, y) => position */
}
.horizontal {
position: absolute;
//top: 0;
left: 50%;
transform: translate(-50%, 0); /* (x, y) => position */
}
div {
padding: 1em;
background-color: grey;
color: white;
}
<body>
<div class="vertical">Vertically left</div>
<div class="horizontal">Horizontal top</div>
<div class="center">Vertically Horizontal</div>
</body>

Centering only vertically
If you don't care about Internet Explorer 6 and 7, you can use a technique that involves two containers.
The outer container:
should have display: table;
The inner container:
should have display: table-cell;
should have vertical-align: middle;
The content box:
should have display: inline-block;
You can add any content you want to the content box without caring about its width or height!
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
}
.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">
Malcolm in the Middle
</div>
</div>
</div>

Centering horizontally and vertically
If you want to center both horizontally and vertically, you also need the following.
The inner container:
should have text-align: center;
The content box:
should re-adjust the horizontal text-alignment to for example text-align: left; or text-align: right;, unless you want text to be centered
Demo:
body {
margin: 0;
}
.outer-container {
position: absolute;
display: table;
width: 100%; /* This could be ANY width */
height: 100%; /* This could be ANY height */
background: #ccc;
}
.inner-container {
display: table-cell;
vertical-align: middle;
text-align: center;
}
.centered-content {
display: inline-block;
text-align: left;
background: #fff;
padding: 20px;
border: 1px solid #000;
}
<div class="outer-container">
<div class="inner-container">
<div class="centered-content">
Malcolm in the Middle
</div>
</div>
</div>
See also this Fiddle!
It can be done in two ways
body{
left: 50%;
top:50%;
transform: translate(-50%, -50%);
height: 100%;
width: 100%;
}
OR
Using flex
body {
height:100%
width:100%
display: flex;
justify-content: center;
align-items: center;
}
align-items:center; makes the content vertically center
justify-content: center;makes the content horizontally center
This is always where I go when I have to come back to this issue.
For those who don't want to make the jump:
Specify the parent container as position:relative or position:absolute.
Specify a fixed height on the child container.
Set position:absolute and top:50% on the child container to move the top down to the middle of the parent.
Set margin-top:-yy where yy is half the height of the child container to offset the item up.
An example of this in code:
<style type="text/css">
#myoutercontainer {position:relative}
#myinnercontainer {position:absolute; top:50%; height:10em; margin-top:-5em}
</style>
...
<div id="myoutercontainer">
<div id="myinnercontainer">
<p>Hey look! I'm vertically centered!</p>
<p>How sweet is this?!</p>
</div>
</div>
I just wrote this CSS and to know more, please go through: This article with vertical align anything with just 3 lines of CSS.
.element {
position: relative;
top: 50%;
transform: perspective(1px) translateY(-50%);
}
For newcomers, please try:
display: flex;
align-items: center;
justify-content: center;
The three lines of code using transform works practically on modern browsers and Internet Explorer:
.element{
position: relative;
top: 50%;
transform: translateY(-50%);
-moz-transform: translateY(-50%);
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
}
I am adding this answer since I found some incompleteness in the previous version of this answer (and Stack Overflow won't allow me to simply comment).
'position' relative messes up the styling if the current div is in the body and has no container div. However 'fixed' seems to work, but it obviously fixes the content in the center of the viewport
Also I used this styling for centering some overlay divs and found that in Mozilla all elements inside this transformed div had lost their bottom borders. Possibly a rendering issue. But adding just the minimal padding to some of them rendered it correctly. Chrome and Internet Explorer (surprisingly) rendered the boxes without any need for padding
CSS Grid
body, html { margin: 0; }
body {
display: grid;
min-height: 100vh;
align-items: center;
}
<div>Div to be aligned vertically</div>
.center{
display: grid;
place-items: center;
}
The answer from Billbad only works with a fixed width of the .inner div.
This solution works for a dynamic width by adding the attribute text-align: center to the .outer div.
.outer {
position: absolute;
display: table;
width: 100%;
height: 100%;
text-align: center;
}
.middle {
display: table-cell;
vertical-align: middle;
}
.inner {
text-align: center;
display: inline-block;
width: auto;
}
<div class="outer">
<div class="middle">
<div class="inner">
Content
</div>
</div>
</div>
Just do it: Add the class at your div:
.modal {
margin: auto;
position: absolute;
top: 0;
right: 0;
left: 0;
bottom: 0;
height: 240px;
}
And read this article for an explanation. Note: Height is necessary.
I did it with this (change width, height, margin-top and margin-left accordingly):
.wrapper {
width: 960px;
height: 590px;
position: absolute;
top: 50%;
left: 50%;
margin-top: -295px;
margin-left: -480px;
}
<div class="wrapper"> -- Content -- </div>
Not answering for browser compatibility but to also mention the new Grid and the not so new Flexbox feature.
Grid
From: Mozilla - Grid Documentation - Align Div Vertically

}
.item1 {

I think a solid solution for all browsers without using Flexbox - "align-items: center;" is a combination of display: table and vertical-align: middle;.
CSS
.vertically-center
{

Especially for parent divs with relative (unknown) height, the centering in the unknown solution works great for me. There are some really nice code examples in the article.
It was tested in Chrome, Firefox, Opera, and Internet Explorer.
/* This parent can be any width and height */
.block {
text-align: center;
}
/* The ghost, nudged to maintain perfect centering */
.block:before {
content: '';
display: inline-block;
height: 100%;
vertical-align: middle;
margin-right: -0.25em; /* Adjusts for spacing */
}
/* The element to be centered, can
also be of any width and height */
.centered {
display: inline-block;
vertical-align: middle;
width: 300px;
}
<div style="width: 400px; height: 200px;">
<div class="block" style="height: 90%; width: 100%">
<div class="centered">
<h1>Some text</h1>
<p>Any other text..."</p>
</div>
</div>
</div>
There is a trick I found out recently: You need to use top 50%, and then you do a translateY(-50%).
.outer-div {
position: relative;
height: 150px;
width: 150px;
background-color: red;
}
.centered-div {
position: absolute;
top: 50%;
-webkit-transform: translateY(-50%);
-ms-transform: translateY(-50%);
transform: translateY(-50%);
background-color: white;
}
<div class='outer-div'>
<div class='centered-div'>
Test text
</div>
</div>
So I have this markup and inside it there is <div class="mask"></div> which sets the blue overlay ontop of the image.
If I don't make the .container position:relative, the title text gets hidden behind the blue layer... Almost as if it's usage is mimicking z-index
Why is this the case?

You need to refer to the specification and more precisely the painting order to understand when each layer is painted.
Without position:relative your element is not positioned and will be painted at the step (4):
For all its in-flow, non-positioned, block-level descendants in tree
order: If the element is a block, list-item, or other block
equivalent:
Then we paint the positioned elements (including the .mask) at the step (8)
All positioned, opacity or transform descendants, in tree order that fall into the following categories
Now when you add position:relative you make the container also positioned thus it will fall in the step (8) too and as described there we consider the tree order since both don't have any z-index specified. So the .container will painted later in this case.
If you change the order of the element (you make the container before the mask) you will notice that position:relative won't have any effect because in both cases the painting order will be the same:
body {
margin: 0;
font-family: arial;
}
section {
position: relative;
background: url(https://preview.webpixels.io/boomerang-v3.6.1/assets/images/backgrounds/slider/img-41.jpg)
no-repeat left center/cover;
height: 70vh;
display: flex;
justify-content: center;
}
.container {
position: relative; /* you can remove this*/
width: 100%;
max-width: 1280px;
display: flex;
justify-content: center;
align-items: center;
color: white;
}
.mask {
position: absolute;
width: 100%;
height: 100%;
background: #3452ff;
opacity: 0.7;
}
<section>
<div class="container">
<h1>Hello World</h1>
</div>
<div class="mask"></div>
</section>
If we check the step (8) it also said opacity or transform which means that if you also change the opacity of the container or add a transform, the order will change too.
body {
margin: 0;
font-family: arial;
}
section {
position: relative;
background: url(https://preview.webpixels.io/boomerang-v3.6.1/assets/images/backgrounds/slider/img-41.jpg)
no-repeat left center/cover;
height: 70vh;
display: flex;
justify-content: center;
}
.container {
transform:translate(0); /*added this*/
width: 100%;
max-width: 1280px;
display: flex;
justify-content: center;
align-items: center;
color: white;
}
.mask {
position: absolute;
width: 100%;
height: 100%;
background: #3452ff;
opacity: 0.7;
}
<section>
<div class="mask"></div>
<div class="container">
<h1>Hello World</h1>
</div>
</section>
It's also trivial to notice that if you add z-index (either negative or positive) you will also affect the painting order and in this case the tree order will have no effect.
Stacking contexts formed by positioned descendants with negative z-indices (excluding 0) in z-index order (most negative first) then tree order
....
Stacking contexts formed by positioned descendants with z-indices greater than or equal to 1 in z-index order (smallest first) then tree order.
We paint the element with negative z-index at (3) and the positive ones at (9) and between those steps we have all the cases where z-index is not involved like described initially.
This is a fascinating question. It appears that when the .mask div is made absolute and taken out of the document flow, it's the positions that are affected, but the stacking order of the elements is still in place. So an element placed before the absolute div appears under the div, and an element placed after the absolute div is stacked after.
This isn't really an answer, I just wanted to demo what I looked at:
body {
margin: 0;
font-family: arial;
}
section {
position: relative;
background: url(https://preview.webpixels.io/boomerang-v3.6.1/assets/images/backgrounds/slider/img-41.jpg) no-repeat left center/cover;

Why don't flex items shrink past content size?
(5 answers)
Closed 2 years ago.
I'm trying to flex the img and .title elements within a flex-column. When the page is resized the image should grow/shrink while maintaining its aspect ratio and the title text should remain the same height at the bottom of the screen. However, when I reduce the screen height the title text is pushed off the screen.
Also, the height of the .title element may not always be a single line, will not be known prior to rendering.

If you add min-height:0 to .container>img it will give the desired result.
body {
height: 100vh;
margin: 0;
padding: 0;
overflow: hidden;
}
.container {
display: flex;
flex-direction: column;
width: 100%;
height: 100%;
}
.container>img {
flex-grow: 1;
flex-shrink: 1;
background-color: blue;
width: 100%;
min-height:0;
object-fit: contain;
}
.container .title {
padding: 10px;
color: white;
text-align: center;
background-color: gray;
}
<div class="container">
<img src="https://cdn.mos.cms.futurecdn.net/paWPwF85Vkcs8YUuyvA3YM-650-80.jpg.webp">

add a wrap to your container to make it flow nicely
.container {
display: flex;
flex-wrap: wrap;
flex-direction: column;
width: 100%;
height: 100%;
and add a flex-basis on your child (img)
.container > img {
flex-grow: 1;
flex-shrink: 1;
flex-basis: 25%;
background-color: blue;
object-fit: contain;
or you can remove the flex-grow, shrink and shorthand it to
flex: 1 1 25%;
is that what you needed?
Background
I am trying to make a div where an image is on one end with a text portion on the other (taking up the rest of the available space). The image is sized relative to the window width and the text is center-aligned within the space available.
Also, the image has icons that are absolutely positioned on it, relative to it's size.
You can test it for yourself here
HTML:
<div id="previousVideo" onclick="backVideo();" title="Back">
<div class="videoNameContainer">
<p class="videoName"></p>
</div>
<div class="videoImageContainer">
<div class="videoImageWrapper">
<img class="videoImage" src="" />
<span class="fa fa-backward"></span>
<p class="videoTime"></p>
</div>
</div>
</div>
CSS:
#previousVideo,
#nextVideo {
display: flex;
padding: 5px;
width: 25%;
height: 40%;
cursor: pointer;
}
.videoNameContainer {
width: 100%;
display: flex;
align-items: center;
height: 100%;
justify-content: center;
}
.videoImageContainer {
height: 100%;
display: flex;
width: 40%;
align-items: center;
}
.videoImageWrapper {
width: 100%;
max-height: 100%;
display: flex;
position: relative;
}
.videoName {
margin: 0;
max-height: 100%;
overflow: hidden;
background-color: white;
}
.videoTime {
position: absolute;
bottom: 0;
right: 3px;
color: white;
margin: 0;
font-size: 0.8em;
}
#previousVideo .videoNameContainer {
margin-right: 5px;
}
#previousVideo .videoImageContainer {
margin-left: auto;
}
.fa-backward, .fa-forward {
position: absolute;
top: 50%;
left: 50%;
margin-right: -50%;
transform: translate(-50%, -50%);
}
Question
Upon resizing the window of Firefox, the image resizes and everything follows the CSS.
Yet, doing the same on Chrome, the image does not resize at all:
Why is this happening? Thanks ahead!
UPDATE:
On adding width:100% to the image, Chrome does not maintain the aspect ratio of the image:
you container is resizing, but the img is overflowing.
You need to add width:100% to your img, so it resizes to whatever width the container has.
.videoImage{
width:100%;
height:100%;
}
It seems in the absense of a width declaration for the image itself, Firefox is resizing the img to the container, while Chrome is just keeping the image actual width.
I have an overlay image that needs to be responsive vertically and horizontally to work on desktop and mobile.
Edit: By vertically responsive, I mean it needs to stay within the window and not overflow below the bottom of the screen.
There's a element on top of the image that needs to stay in the same place, and the image must retain its aspect ratio.
I'd rather do this with pure CSS, but could use JS for browser compatibility or a simpler solution.

Try setting the width and height to auto:
.img-container img {
display: block;
width: auto;
height: auto;
}
Or I have set the width or height, then auto the other which has worked.
Check out CSS media queries.
The max-width and max-height CSS attributes should be able to solve your problem once you pick the appropriate breakpoints for the screen sizes you want to cover.

I just updated codepen & also putted the code here too.
