As you can see, the list-items in the first row have same height. But items in the second row have different heights. I want all items to have a uniform height.

Is there any way to achieve this without giving fixed-height and only using flexbox?

enter image description here

Here is my code 

.list {
  display: flex;
  flex-wrap: wrap;
  max-width: 500px;
}
.list-item {
  background-color: #ccc;
  display: flex;
  padding: 0.5em;
  width: 25%;
  margin-right: 1%;
  margin-bottom: 20px;
}
.list-content {
  width: 100%;
}
<ul class="list">
  <li class="list-item">
    <div class="list-content">
      <h2>box 1</h2>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
      <h3>box 2</h3>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
    </div>
  </li>

  <li class="list-item">
    <div class="list-content">
      <h3>box 2</h3>
      <p>Lorem ipsum dolor</p>
    </div>
  </li>

  <li class="list-item">
    <div class="list-content">
      <h3>box 2</h3>
      <p>Lorem ipsum dolor</p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
      <h1>h1</h1>
    </div>
  </li>
</ul>

The answer is NO.

The reason is provided in the flexbox specification:

6. Flex Lines

In a multi-line flex container, the cross size of each line is the minimum size necessary to contain the flex items on the line.

In other words, when there are multiple lines in a row-based flex container, the height of each line (the "cross size") is the minimum height necessary to contain the flex items on the line.

Equal height rows, however, are possible in CSS Grid Layout:

Otherwise, consider a JavaScript alternative.

You can accomplish that now with display: grid:

.list {
  display: grid;
  overflow: hidden;
  grid-template-columns: repeat(3, 1fr);
  grid-auto-rows: 1fr;
  grid-column-gap: 5px;
  grid-row-gap: 5px;
  max-width: 500px;
}
.list-item {
  background-color: #ccc;
  display: flex;
  padding: 0.5em;
  margin-bottom: 20px;
}
.list-content {
  width: 100%;
}
<ul class="list">
  <li class="list-item">
    <div class="list-content">
      <h2>box 1</h2>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
      <h3>box 2</h3>
      <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
    </div>
  </li>

  <li class="list-item">
    <div class="list-content">
      <h3>box 2</h3>
      <p>Lorem ipsum dolor</p>
    </div>
  </li>

  <li class="list-item">
    <div class="list-content">
      <h3>box 2</h3>
      <p>Lorem ipsum dolor</p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
      <h1>h1</h1>
    </div>
  </li>
</ul>

Although the grid itself is not flexbox, it behaves very similar to a flexbox container, and the items inside the grid can be flex.

The grid layout is also very handy in the case you want responsive grids. That is, if you want the grid to have a different number of columns per row you can then just change grid-template-columns:

grid-template-columns: repeat(1, 1fr); // 1 column
grid-template-columns: repeat(2, 1fr); // 2 columns
grid-template-columns: repeat(3, 1fr); // 3 columns

and so on...

You can mix it with media queries and change according to the size of the page.

Sadly there is still no support for container queries / element queries in the browsers (out of the box) to make it work well with changing the number of columns according to the container size, not to the page size (this would be great to use with reusable webcomponents).

    This is the kind of "can do" approach that I like! Thanks for the working example as well – hananamar Nov 19 '19 at 11:27

    this does not implement the same behaviour as flexbox wrapping does. also the question asked for an answer using flexbox. – Andy Dec 20 '20 at 13:13

    @Andy As the accepted answer already says, you can't achieve that with flexbox (without js). I also made sure to say that it's really not flexbox ("Although the grid itself is not flexbox..."), and I'm not saying that the behavior is exactly the same as flexbox (which is obvious), but it's very similar and solves the issue asked (except for the fact that it's not flexbox), and **more importantly**, it may solve similar issues for other users searching for a similar approach. Furthermore, the items can be flexbox (as opposed to a table layout, that expect table items, for example). – Lucas Basquerotto Dec 21 '20 at 12:15

You can with flexbox for horizontal issues:

.flex-list {
    padding: 0;
    list-style: none;
    display: flex;
    align-items: stretch;
    flex-wrap: wrap;
    justify-content: center;
    gap: .5rem;
}
.flex-list li {
    width: 120px;
    padding: .5rem;
    border-radius: 1rem;
    background: yellow;
}
<ul class="flex-list">
  <li>title 1</li>
  <li>title 2</li>
  <li>title 3<br>new line</li>
  <li>title 4<br>new line</li>
  <li>title 5<br>new<br>line</li>
  <li>title 6</li>
</ul>

Or with grid for both horizontal and vertical issues:

.grid-list {
   padding: 0;
   list-style: none;
   display: grid;
   grid-auto-columns: 1fr;
   grid-auto-rows: 1fr;
   grid-template-columns: repeat(3, 1fr);
   gap: .5rem;
}
    
.grid-list li {
   padding: .5rem;
   border-radius: 1rem;
   background: yellow;
}   

.grid-list li:last-child {
   grid-column-start: 2;
}  
<ul class="grid-list">
    <li>title 1</li>
    <li>title 2<br>new<br>line</li>
    <li>title 3<br>new line</li>
    <li>title 4<br>new line</li><li>title 5</li>
    <li>title 6<br>new<br>line</li>
    <li>title 7</li>
   </ul>

Flexbox: Make all flexitems the same height?

n the child item

align-self: stretch;

or in the parent container justify-content: stretch;

No, you can't achieve that without setting a fixed height (or using a script).

Here are 2 answers of mine, showing how to use a script to achieve something like that:

This seems to be working in cases with fixed parent height (tested in Chrome and Firefox):

.child {
        height    : 100%;
        overflow  : hidden;
}

.parent {
        display: flex;
        flex-direction: column;
        height: 70vh; // ! won't work unless parent container height is set
        position: relative;
}

If it's not possible to use grids for some reason, maybe it's the solution.

If you know the items you are mapping through, you can accomplish this by doing one row at a time. I know it's a workaround, but it works.

For me I had 4 items per row, so I broke it up into two rows of 4 with each row height: 50%, get rid of flex-grow, have <RowOne /> and <RowTwo /> in a <div> with flex-column. This will do the trick

<div class='flexbox flex-column height-100-percent'>
   <RowOne class='flex height-50-percent' />
   <RowTwo class='flex height-50-percent' />
</div>

you should use the justify-content:stretch and align-items:stretch properties for your flex display and I think this would make the height of each and every element, in flex, equal

You can achieve this with:

align-items: stretch;

This will stretch every item to the height of the element with the maximum height in the flex.

you can do it by fixing the height of "P" tag or fixing the height of "list-item".

I have done by fixing the height of "P"

and overflow should be hidden.

.list{
  display: flex;
  flex-wrap: wrap;
  max-width: 500px;
}

.list-item{
  background-color: #ccc;
  display: flex;
  padding: 0.5em;
  width: 25%;
  margin-right: 1%;
  margin-bottom: 20px;
}
.list-content{
  width: 100%;
}
p{height:100px;overflow:hidden;}
<ul class="list">
  <li class="list-item">
    <div class="list-content">
    <h2>box 1</h2>
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. </p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
    <h3>box 2</h3>
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
    </div>
  </li>
  
    <li class="list-item">
    <div class="list-content">
    <h3>box 2</h3>
    <p>Lorem ipsum dolor</p>
    </div>
  </li>
  
    <li class="list-item">
    <div class="list-content">
    <h3>box 2</h3>
    <p>Lorem ipsum dolor</p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
      <h1>h1</h1>
    </div>
  </li>
</ul>

  • Seems not the answer I'm looking for, if the content become larger, it will be hidden. – Jinu Kurian Mar 15 '16 at 09:45
  • @JinuKurian where I am adding overflow:hidden, If you change that to overflow:auto then scroll will appear. then u can able to see full content also – Ajay Malhotra Mar 15 '16 at 09:47

In your case height will be calculated automatically, so you have to provide the height
use this 

.list-content{
  width: 100%;
  height:150px;
}

    I'm sorry, the height may vary with the contents. So can't give fixed height. – Jinu Kurian Mar 15 '16 at 07:51
  • Heights are calculated automatically, so with your different content, heights will be different,so you have to use fixed height otherwise you can't get uniform heights. – Tom Mar 15 '16 at 07:57

for same height you should chage your css "display" Properties. For more detail see given example.

.list{
  display: table;
  flex-wrap: wrap;
  max-width: 500px;
}

.list-item{
  background-color: #ccc;
  display: table-cell;
  padding: 0.5em;
  width: 25%;
  margin-right: 1%;
  margin-bottom: 20px;
}
.list-content{
  width: 100%;
}
<ul class="list">
  <li class="list-item">
    <div class="list-content">
    <h2>box 1</h2>
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. </p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
    <h3>box 2</h3>
    <p>Lorem ipsum dolor sit amet, consectetur adipisicing elit.</p>
    </div>
  </li>
  
    <li class="list-item">
    <div class="list-content">
    <h3>box 2</h3>
    <p>Lorem ipsum dolor</p>
    </div>
  </li>
  
    <li class="list-item">
    <div class="list-content">
    <h3>box 2</h3>
    <p>Lorem ipsum dolor</p>
    </div>
  </li>
  <li class="list-item">
    <div class="list-content">
      <h1>h1</h1>
    </div>
  </li>
