How to line up consecutive divs left and right? - javascript

Hello I'm not too good with css/floats/blocks etc.
I have this sort of setup
<div class="blue">1</div>
<div class="red">2</div>
<div class="blue">3</div>
<div class="red">4</div>
<div class="blue">5</div>
<div class="red">6</div>
I want to style it so 1 and 2 are on the same line (floated left and right), then 3 and 4 are on the same line (floated left and right) and so on and so forth.
Currently these elements are created in a loop. I have tried all sorts of methods to get the elements to line up how I want to no avail.

I think you want to make them two per row correct?
You can add a flex property to the parent container. Set the flex-wrap to wrap, then add a 50% width on your child elements (taking into account any inherited margin or padding effecting the layouts width to not overflow the flex-wrap), then justify-content to space-between, this will force the elements to their respective sides or a better way to put it is; place the "left over" space the children on that row are not taking up, in the middle of the two elements.
* { /* set box-sizing on all elements to border-box */
box-sizing: border-box;
}
body { /* remove any margin or padding from the body */
margin: 0;
padding: 0;
}
#cont { /* add display flex, flex-wrap and justify-content to space between */
display: flex;
flex-wrap: wrap;
justify-content: space-between;
}
#cont>div { /* Set your child divs to a percentage that will only give you two per row
the flex-wrap will push elements down */
width: 50%;
}
.blue {
background-color: lightblue;
border: 1px solid darkblue;
}
.red {
background-color: pink;
border: 1px solid darkred;
text-align: right; /* remove if you want standard left side text-alignment on red elements */
}
<div id="cont">
<div class="blue">1</div>
<div class="red">2</div>
<div class="blue">3</div>
<div class="red">4</div>
<div class="blue">5</div>
<div class="red">6</div>
</div>
If this is not what you were looking for let me know and I can edit or remove this answer.

How to make the last element of every flex-wrapped row take up the remaining space? [duplicate]

My problem is that I want the flexbox with variable range width, and all works well, but not on the last row. I want the same dimension for all children even where the row is not full of children (the last row).
#products-list {
position:relative;
display: flex;
flex-flow: row wrap;
width:100%;
}
#products-list .product {
min-width:150px;
max-width:250px;
margin:10px 10px 20px 10px;
flex:1;
}
I created a dynamic situation in jsFiddle
My flex divs can shrink until 150px and grow up to 250px, but all must be with the same size (and obviously I want a CSS solution, with JS I know the way).
Unfortunately, in the current iteration of flexbox (Level 1), there is no clean way to solve the last-row alignment problem. It's a common problem.
It would be useful to have a flex property along the lines of:
last-row
last-column
only-child-in-a-row
alone-in-a-column
This problem does appear to be a high priority for Flexbox Level 2:

Although this behavior is difficult to achieve in flexbox, it's simple and easy in CSS Grid Layout:
Equal width flex items even after they wrap
In case Grid is not an option, here's a list of similar questions containing various flexbox hacks:
Properly sizing and aligning the flex item(s) on the last row
Flex-box: Align last row to grid
Flexbox wrap - different alignment for last row
How can a flex item keep the same dimensions when it is forced to a new row?
Selector for an element alone in a row?
Aligning elements in last flexbox row
How can I allow flex-items to grow while keeping the same size?
Left-align last row of flexbox using space-between and margins
Inconsistent margin between flex items on last row
How to keep wrapped flex-items the same width as the elements on the previous row?
How to align left last row/line in multiple line flexbox
Last children of grid get giant gutter cause of flexbox space-between
Managing justify-content: space-between on last row
Flexbox space between behavior combined with wrap
Possible to use CSS Flexbox to stretch elements on every row while maintaining consistent widths?
As a quick and dirty solution one can use:
.my-flex-child:last-child/*.product:last-child*/ {
flex-grow: 100;/*Or any number big enough*/
}
You could try using grid instead of flexbox here:
#products-list {
display: grid;
grid-gap: 5px;
grid-template-columns: repeat(auto-fit, minmax(100px, 250px)); //grid automagic
justify-content: start; //start left
}

There is a great solution that works always.
add a div with class product (The same class for other items that are under flex) and add a style for this div:height:0px;
you need to add as many dives that are possible to be in one row.
<div class="product" style="height:0px">
as many that can be in one row.
That's all. Works always.
If all your rows have the same number of items, you can use :nth-last-child. For example, if all the rows have 3 items, you can do something like this to remove the margin of the last 3 items:
.container{
display: flex;
flex-wrap: wrap;
background: yellow;
}
.item{
width: calc((100% - 2*10px)/3);
height: 50px;
background: blue;
color: white;
margin-right: 10px;
margin-bottom: 10px;
padding: 5px;
box-sizing: border-box;
}
/* last item of each row */
.item:nth-child(3n){
margin-right: 0;
font-size: 150%;
}
/* last 3 items */
.item:nth-last-child(-n+3){
margin-bottom: 0;
background: green;
}
<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>
A simple trick adds a flexible space to fill the rest of the last row:
#products-list{
display:flex;
flex-flow: row wrap;
justify-content:space-between;
}
#products-list::after {
content: "";
flex: auto;
flex-basis: 200px;/*your item width*/
flex-grow: 0;
}
But you shouldn't use margins on items then. Rather wrap them into containers with padding.
I used this workaround, even if it's not very elegant and it doesn't use the power of Flexbox.
It can be carried out on the following conditions:
All the items have the same width
The items have a fixed width
You use SCSS/SASS (can be avoided though)
If this is the case, you can use the following snippet:
$itemWidth: 400px;
$itemMargin: 10px;
html, body {
margin: 0;
padding: 0;
}
.flex-container {
display: flex;
flex-direction: row;
flex-wrap: wrap;
margin: 0 auto;
border: solid 1px blue;
}
#for $i from 1 through 10 {
#media only screen and (min-width: $i * $itemWidth + 2 * $i * $itemMargin) {
.flex-container {
width: $i * $itemWidth + 2 * $i * $itemMargin;
}
}
}
.item {
flex: 0 0 $itemWidth;
height: 100px;
margin: $itemMargin;
background: red;
}
<div class="flex-container">
<div class="item"></div>
<div class="item" style="flex: 500 0 200px"></div>
<div class="item"></div>
<div class="item"></div>
<div class="item"></div>
</div>
Here I have created an example on codepen which also implements margin.
The second and the third conditions can be avoided respectively using css variables (if you decided to provide support for it) and compiling the above scss snippet.
Well, it's true, we could do it also before flexbox, but display: flex can be still essential for a responsive design.
I was facing this same issue where I wanted to have a variable number of items in a resizable container.
I wanted to use all of the horizontal space, but have all of the flex items at the same size.
I ultimately came up with a javascript approach that dynamically added padding spacers as the container was resized.
function padLastFormRow() {
let topList = [];
let nSpacersToAdd = 0;
$('#flexContainer').find('.formSpacer').remove();
$('#flexContainer').find('.formItem').each(function(i, formItem) {
topList.push($(formItem).position().top);
});
let allRowLengths = getFlexLineLengths(topList);
let firstRowLength = allRowLengths[0];
let lastRowLength = allRowLengths[((allRowLengths.length) - 1)];
if (lastRowLength < firstRowLength) {
nSpacersToAdd = firstRowLength - lastRowLength ;
}
for (var i = 1; i <= nSpacersToAdd; i ++) {
$('#flexContainer').append(formSpacerItem);
}
}
Please see my Fiddle:

I was having a similar challenge with menu rows. I wanted more spacing on the top of the second row of menu items.
The use of flex-box's row-gap worked well.
https://developer.mozilla.org/en-US/docs/Web/CSS/row-gap
.menu {
display: flex;
flex-wrap: wrap;
row-gap: 10px;
}
This added a margin-top type effect to menu items were wrapped to the second line.
If all your rows have the same number of items, you can use :nth-last-child. For example, if all the rows have 3 items, you can do something like this:
.container{
display: flex;
flex-wrap: wrap;
background: yellow;
}
.item{
width: calc((100% - 2*10px)/3);
height: 50px;
background: blue;
color: white;
margin-right: 10px;
margin-bottom: 10px;
padding: 5px;
box-sizing: border-box;
}
// last item of each row
.item:nth-child(3n){
margin-right: 0;
background: green;
}
// last 3 items
.item:nth-last-child(-n+3){
margin-bottom: 0;
font-size: 150%;
}
<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>

How to set column width which uses flex

I am working on react web app which has less styling, so under
wrapper I have 3 columns, such that leftWrap is col-3, rightWrap is
col-4, and rest width is centerWrap. How can i apply flex while i just
know its col-* classnames
<div className={styles.Home__wrapper}>
<div className={styles.Home__leftWrap}> .... </div>
<div className={styles.Home__centerWrap}> .... </div>
<div className={styles.Home__rightWrap}> .... </div>
</div>
.Home {
&__wrapper {
display : flex;
flex-wrap: nowrap;
width : 100%;
box-sizing: border-box;
}
&__leftWrap {
display : flex;
}
&__rightWrap {
display : flex;
}
&__centerWrap {
display : flex;
}
}
How to set width to each column className as per above mentioned, is
it through cal() method
Set the display CSS attribute on the container div to flex, and play with the flex attribute on the children elements. Flex will sum up the flex number assigned to each children element to calculate the "total" steps to be filled, then calculate the value of each step based on the available space remaining and calculate the display width of each child by multiplying the calculated step width value by the child element flex value. In your case, it looks like your left and right children have fixed widths, and you want the center element to take the remaining space, so just set flex to 1 on the center element.
._wrapper {
display : flex;
flex-wrap: nowrap;
box-sizing: border-box;
}
._leftWrap {
width: 50px;
background-color: red;
}
._rightWrap {
width: 100px;
background-color: blue;
}
._centerWrap {
flex: 1;
background-color: yellow;
}
<div class="_wrapper">
<div class="_leftWrap"> .... </div>
<div class="_centerWrap"> .... </div>
<div class="_rightWrap"> .... </div>

Flex transition: Stretch (or shrink) to fit content

I have coded a script (with the help of a user here) which allows me to expand a selected div and make the other divs behave accordingly by stretching equally to fit the remaining space (except the first one which width is fixed).
And here is a picture of what I want to achieve:
For that I use flex and transitions.
It works well, but the jQuery script specifies a "400%" stretch value (which is great for testing).
Now I would like the selected div to expand/shrink to exactly fit the content instead of the "400%" fixed value.
I have no idea how I could do that.
Is it possible ?
I tried to clone the div, fit it to the content, get its value and then use this value to transition BUT this means I have an initial width in percentages but a target value in pixels. That doesn't work.
And if I convert the pixel value in percentages, then the result doesn't exactly fit the content for whatever reason.
In all cases, this seems a bit of a complicated way to achieve what I want anyway.
Isn't there any flex property that could be transitioned in order to fit the content of a selected div?
Here is the code (edited/simplified since for a better read) :
var expanded = '';
$(document).on("click", ".div:not(:first-child)", function(e) {
var thisInd =$(this).index();
if(expanded != thisInd) {
//fit clicked fluid div to its content and reset the other fluid divs
$(this).css("width", "400%");
$('.div').not(':first').not(this).css("width", "100%");
expanded = thisInd;
} else {
//reset all fluid divs
$('.div').not(':first').css("width", "100%");
expanded = '';
}
});
.wrapper {
overflow: hidden;
width: 100%;
margin-top: 20px;
border: 1px solid black;
display: flex;
justify-content: flex-start;
}
.div {
overflow: hidden;
white-space: nowrap;
border-right: 1px solid black;
text-align:center;
}
.div:first-child {
min-width: 36px;
background: #999;
}
.div:not(:first-child) {
width: 100%;
transition: width 1s;
}
.div:not(:first-child) span {
background: #ddd;
}
.div:last-child {
border-right: 0px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Click on the div you want to fit/reset (except the first div)
<div class="wrapper">
<div class="div"><span>Fixed</span></div>
<div class="div"><span>Fluid (long long long long long text)</span></div>

Thank you all !
It is possible to solve it using max-width and calc().
First, replace width: 100% with flex: 1 for the divs in CSS, so they will grow, which is better in this case. In addition, use transition for max-width.
Now, we have to store some relevant values:
The amount of divs that will be animated (divsLength variable) - 3 in this case.
The total width used for the fixed div and the borders (extraSpace variable) - 39px in this case.
With those 2 variables, we can set a default max-width (defaultMaxWidth variable) to all the divs, as well as using them later. That is why they are being stored globally.
The defaultMaxWidth is calc((100% - extraSpace)/divsLength).
Now, let's enter the click function:
To expand the div, the width of the target text will be stored in a variable called textWidth and it will be applied to the div as max-width. It uses .getBoundingClientRect().width (since it return the floating-point value).
For the remaining divs, it is created a calc() for max-width that will be applied to them.
It is: calc(100% - textWidth - extraScape)/(divsLength - 1).
The calculated result is the width that each remaining div should be.
When clicking on the expanded div, that is, to return to normal, the default max-width is applied again to all .div elements.
var expanded = false,
divs = $(".div:not(:first-child)"),
divsLength = divs.length,
extraSpace = 39, //fixed width + border-right widths
defaultMaxWidth = "calc((100% - " + extraSpace + "px)/" + divsLength + ")";
divs.css("max-width", defaultMaxWidth);
$(document).on("click", ".div:not(:first-child)", function (e) {
var thisInd = $(this).index();
if (expanded !== thisInd) {
var textWidth = $(this).find('span')[0].getBoundingClientRect().width;
var restWidth = "calc((100% - " + textWidth + "px - " + extraSpace + "px)/" + (divsLength - 1) + ")";
//fit clicked fluid div to its content and reset the other fluid divs
$(this).css({ "max-width": textWidth });
$('.div').not(':first').not(this).css({ "max-width": restWidth });
expanded = thisInd;
} else {
//reset all fluid divs
$('.div').not(':first').css("max-width", defaultMaxWidth);
expanded = false;
}
});

Click on the div you want to fit/reset (except the first div)
<div class="wrapper">
<div class="div"><span>Fixed</span></div>
<div class="div"><span>Fluid (long long long long text)</span></div>
<div class="div"><span>Fluid</span></div>
<div class="div"><span>Fluid</span></div>
</div>
This approach behaves dynamically and should work on any resolution.
The only value you need to hard code is the extraSpace variable.
You need to deal with the width or calc functions. Flexbox would have a solution.
To make all divs equal (not first one) we use flex: 1 1 auto.
<div class="wrapper">
<div class="div"><span>Fixed</span></div>
<div class="div"><span>Fluid (long long long long text)</span></div>
<div class="div"><span>Fluid</span></div>
<div class="div"><span>Fluid</span></div>
</div>
Define flex rules for your normal div and selected div. transition: flex 1s; is your friend. For selected one we don't need flex grow so we use flex: 0 0 auto;
.wrapper {
width: 100%;
margin-top: 20px;
border: 1px solid black;
display: flex;
}
.div {
white-space: nowrap;
border-right: 1px solid black;
transition: flex 1s;
flex: 1 1 auto;
}
.div.selected{
flex: 0 0 auto;
}
.div:first-child {
min-width: 50px;
background: #999;
text-align: center;
}
.div:not(:first-child) {
text-align: center;
}
.div:last-child {
border-right: 0px;
}
div:not(:first-child) span {
background: #ddd;
}
Add selected class each time when the user clicks a div. You can also use toggle for the second click so you can save selected items in a map and you can show multiple selected items (not with this code example of course).
$(document).on("click", ".div:not(:first-child)", function(e) {
const expanded = $('.selected');
$(this).addClass("selected");
if (expanded) {
expanded.removeClass("selected");
}
});

After a few trial versions, this seems to be my shortest and most straighforward solution.
All that essentially needs to be done is have Flexbox stretch the <div> elements to their limits by default, but when <span> clicked, constraint the stretch of the <div> to <span> width ...
pseudo code:
when <span> clicked and already toggled then <div> max-width = 100%, reset <span> toggle state
otherwise <div> max-width = <span> width, set <span> toggle state
I have split the CSS into a 'relevant mechanism' and 'eye-candy only' section for easy reading (and code recyling).
The code is heavily commented, so not much text here...
Quirk Somehow there is an extra delay in the transition when switching the div from max-width: 100% to max-width = span width. I've checked this behaviour in Chrome, Edge, IE11 and Firefox (all W10) and all seem to have this quirk. Either some browser internal recalc going on, or maybe the transition time is used twice ('feels like'). Vice Versa, oddly enough, there is no extra delay.
However, with a short transition time (e.g. 150ms, as I am using now) this extra delay is not/hardly noticable. (Nice one for another SO question...)
$(document).on('click', '.wrapper>:not(.caption) span', function (e) {
// Save the current 'toggle' status
var elemToggled = e.target.getAttribute('toggled');
// Set parent max-width to maximum space or constraint to current child width
e.target.parentElement.style.maxWidth =
(elemToggled=="true") ? '100%' : parseFloat(window.getComputedStyle(e.target).width) + 'px';
// (Re)set child toggle state
e.target.setAttribute('toggled', (elemToggled=="true") ? false : true);
});

UPDATE
New version that resets all other <div>. I truly hate the jumpiness, but that is due to Flexbox stretching and the transition value. Without transition no jumps visible. You need to try out what works for you.
I only added document.querySelectorAll() to the javascript code.
$(document).on('click', '.wrapper>:not(.caption) span', function (e) {
var elemToggled = e.target.getAttribute('toggled'); // Toggle status
var elemWidth = parseFloat(window.getComputedStyle(e.target).width); // Current element width
// reset ALL toggles but 'this'...
document.querySelectorAll('.wrapper>:not(.caption) span')
.forEach( function (elem,idx) {
if (elem != this){
elem.parentElement.style.maxWidth = '100%';
elem.setAttribute('toggled',false);
};
});
// Set parent max-width to maximum space or constraint to current child width
e.target.parentElement.style.maxWidth =
(elemToggled=="true") ? '100%' : parseFloat(window.getComputedStyle(e.target).width) + 'px';
// (Re)set child toggle state
e.target.setAttribute('toggled', (elemToggled=="true") ? false : true);
});

If you need only one row, there is a simpler solution based on this code : https://jsfiddle.net/jpeter06/a5cu52oy/
with the css flex modified for columns instead of rows :
.container {
flex-grow: 10;
flex-shrink: 0;
flex-basis: auto;
display: flex;
flex-direction: row;
width: 100%;
}
.item { min-width:30px;
flex-basis:30px;
overflow-x:hidden;
transition: flex-basis 500ms ease-in-out;
}
.expanded {
flex-basis: 20em;
}
html, body {
width: 100%; height: 100%;
margin: 0; padding: 0; border: 0; overflow: hidden;
}
html code :
<div class="container">
<div class="item" style="background: red">a<br/>a<br/>a<br/>a<br/>a<br/>a<br/>a<br/>a<br/></div>
<div class="item" style="background: green">b<br/>b<br/>b<br/>b</div>
<div class="item" style="background: blue">c<br/>c<br/>c<br/>c</div>
</div>
JS code :
$(document).ready(function() {
$(".item").click(function() {
$(this).addClass('expanded');
$(".item").not(this).each(function() {
$(this).removeClass("expanded");
});
});
});

How to align html?

I'm using display flex to display multiple items in one big container (parentDiv). The code is working fine but I get big problems with horizontal centering the items (especially If there are only a few items they should get horizontally centered) so I was using justify-content what leads to big issues:
The parent div is not able to display all items anymore. The first item that gets displayed is the item "04" while it should be "01". How to avoid this?
Please have a look at this code:
#bigDiv {
position: absolute;
width: 100%;
height: 100%;
}
#parentDiv {
width: 90%;
height: 50%;
overflow-y: hidden;
overflow-x: scroll;
text-align: center;
white-space: nowrap;
background: red;
display: flex;
justify-content: center;
align-items: center;
}
.item {
color: white;
background: blue;
flex: 0 0 4%;
margin: 0 3%;
}
.item::after {
content: "";
display: block;
padding-bottom: 100%;
}
<div id="bigDiv">
<div id="parentDiv">
<div class="item">01</div>
<div class="item">02</div>
<div class="item">03</div>
<div class="item">04</div>
<div class="item">05</div>
<div class="item">06</div>
<div class="item">07</div>
<div class="item">08</div>
<div class="item">09</div>
<div class="item">10</div>
<div class="item">11</div>
<div class="item">12</div>
<div class="item">13</div>
<div class="item">14</div>
<div class="item">15</div>
<div class="item">16</div>
</div>
</div>
See this image:
My intentions: The parent div should be able to show all of the items (starting with "01" - and the last element should be the "16"-one)
Note: If there are only 4 or less items they should get centered horizontally. (The reason why I added justify-content).
You're fiting 160% into 100%. And you want it centered. And it works: the 160% total width of the resulting children is nicely centered.
But you're also expecting whatever is outside the parent to be accessible.
It's pretty much like making a child element go outside of its parent by -30% to the left or to the top (by any other method) and expecting the parent to allow you to scroll to it. It's not going to happen!
If it did, the child would no longer be placed at -30%, it would be placed at 0%. Scrollbars will never scroll to left or top negative space. It's by design. You need to take it into consideration when designing your page.
Whenever you center a bigger child into a smaller parent you won't be able to use parent's scrollbars to scroll to the beginning of the child. So anything preventing the child positioning in the parent's left negative space will fix it.

Make a grid of four divs expand to match the tallest height

I'm trying to create a grid layout that sizes all child divs to match the tallest div in the group. For example, I have a 2x2 grid, with each div in the grid containing some text. The div that contains the most text is tallest, and should push the height on the other 3 divs to match.
I can get the div heights to match on each row using display: flex; and flex-wrap: wrap;, but I need all rows to match in height.
Is this possible to accomplish with CSS, or will I need to resort to jQuery?
<section class="grid two">
<div>
<div>
<p>The top left div</p>
</div>
</div>
<div>
<div>
<p>The top right div</p>
</div>
</div>
<div>
<div>
<p>The bottom left div</p>
</div>
</div>
<div>
<div>
<p>The bottom right div</p>
<p>this has more text, and should casue the rest to strecth to match its height.</p>
</div>
</div>
</section>
And my current CSS is:
.grid {
display: flex;
flex-wrap: wrap;
}
.grid > div {
box-sizing: border-box;
display: flex;
flex-directon: column;
padding: 10px;
width: 50%;
}
.grid > div > div {
background: #EEE;
flex: 1 1 auto;
width: 100%;
}
Here's a fiddle: http://jsfiddle.net/g41xas6w/
Update 1: I can't used a fixed height for two reasons:
The client will be able to edit this text, so I can't always know what the height will be.
This is a responsive site, so I'd have to do a whole bunch of breaks to ensure that things are always displaying at the correct height.

Please see the link above. These guys have created a jQuery plugin to achieve the effect you are after.
Your solution would work only for the 4 DIVs in a single horizontal line. Change the width and look! If you require the 2X2, the dynamically getting the height of all 4 to be same is not possible with only CSS. You need to either use script to control it or have a height set which would stop being dynamic!
If you put a height tag in the .grid > div with for example 200px it will all be 200px
.grid > div {
box-sizing: border-box;
display: flex;
flex-directon: column;
padding: 10px;
width: 50%;
height: 200px;
}
