How can I make Bootstrap columns all the same height?

I'm using Bootstrap. How can I make three columns all the same height?

Here is a screenshot of the problem. I would like the blue and red columns to be the same height as the yellow column.

Here is the code:

some content
catz
some more content

There is an article in the bootstrap website with a 5-lines solution getbootstrap.com.vn/examples/equal-height-columns
The example on Bootstrap breaks responsiveness Eduard. The flex .row is missing flex-wrap: wrap;. Here's an example of it working with responsiveness: codepen.io/bootstrapped/details/RrabNe
Possible Workaround – A Transparent image 1 pixel wide in the other columns. This new one pixel width image matches the pixel height of the cats pic in the above example. (May not work or be practical in your situation)
In Bootstrap 4, we can use the card for the same

LATEST SOLUTION (2022)

Solution 4 using Bootstrap 4 or 5

Bootstrap 4 and 5 use Flexbox by default, so there is no need for extra CSS.

Demo

<div class="container">
    <div class="row ">
        <div class="col-md-4" style="background-color: red">
          some content
        </div>
        <div class="col-md-4" style="background-color: yellow">
          catz
          <img width="100" height="100" src="https://placekitten.com/100/100/">
        </div>
        <div class="col-md-4" style="background-color: green">
          some more content
        </div>
    </div>
</div>

Solution 1 using negative margins (doesn't break responsiveness)

Demo

.row{
    overflow: hidden; 
}

[class*="col-"]{
    margin-bottom: -99999px;
    padding-bottom: 99999px;
}

Solution 2 using table

Demo

.row {
    display: table;
}

[class*="col-"] {
    float: none;
    display: table-cell;
    vertical-align: top;
}

Solution 3 using flex added August 2015. Comments posted before this don't apply to this solution.

Demo

.row {
  display: -webkit-box;
  display: -webkit-flex;
  display: -ms-flexbox;
  display:         flex;
  flex-wrap: wrap;
}
.row > [class*='col-'] {
  display: flex;
  flex-direction: column;
}

Think of it as the column being sucked into negative space. If you remove the overflow you'll see what's going on.
If targeting the bootstrap column class specifically you should probably use an anchor ^ instead of a wildcard *. Using ^ will say that the class must start with col- where as the wildcard shown will match any class with col- anywhere in the string, possibly having undesired effects on styles where you may have used the convention col-. (i.e. stuff-col-morestuff).
Nice answer, with some caveats. Solution 1 disables the float and therefore breaks the bootstrap grid responsive behavior. Solution 2 (explained in greater depth in positioniseverything.net/articles/onetruelayout/equalheight) doesn't show the bottom border (as it is clipped somewhere in the padding space).
Solution 3 breaks row responsiveness.
@Popnoodles you should add flex-wrap: wrap; to the third example to enable responsiveness. You also will want to add display: flex; flex-direction: column; to the column class. If you are going to use .row and not a custom class, you'll need to provide a fallback for older browsers changing the display flex back. Here's an example

Update 2021

Bootstrap 4 + 5

Flexbox is now used by default in Bootstrap 4 (and Bootstrap 5) so there is no need for the extra CSS to make equal height columns: https://www.codeply.com/go/IJYRI4LPwU

Example:

<div class="container">
    <div class="row">
        <div class="col-md-6"></div>
        <div class="col-md-6"></div>
    </div>
</div>

Bootstrap 3

Best approach for Bootstap 3.x — using CSS flexbox (and requires minimal CSS)…

.equal {
  display: flex;
  display: -webkit-flex;
  flex-wrap: wrap;
}

Bootstrap same height flexbox example

To only apply the same height flexbox at specific breakpoints (responsive), use a media query. For example, here is sm (768px) and up:

@media (min-width: 768px) {
  .row.equal {
    display: flex;
    flex-wrap: wrap;
  }
}

This solution also works well for multiple rows (column wrapping): https://www.codeply.com/go/bp/gCEXzPMehZ

Other workarounds

These options will be recommended by others, but are not a good idea for responsive design. These only work for simple single row layouts w/o column wrapping.

Using huge negative margins & padding Using display:table-cell (this solution also affects the responsive grid, so a @media query can be used to only apply table display on wider screens before the columns stack vertically)


You can use a media-query to only apply the flexbox on larger/wider devices. I updated the bootply: bootply.com/Cn6fA6LuTq
In case anyone is interested, I have created a pen to demonstrate similar effects on a form using flexbox.
It's a known Safari bug with flexbox: proof: bugs.webkit.org/show_bug.cgi?id=137730
@Stanley the comment about "no longer responsive" is old and irrelevant.
This is the only fix that worked for me. Thanks Zim this is great!

No JavaScript needed. Just add the class .row-eq-height to your existing .row just like this:

<div class="row row-eq-height">
  <div class="col-xs-12 col-sm-4 panel" style="background-color: red">
    some content
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: yellow">
    kittenz
  <img src="http://placekitten.com/100/100">
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: blue">
    some more content
  </div>
</div>

Tip: if you have more than 12 columns in your row, the bootstrap grid will fail to wrap it. So add a new div.row.row-eq-height each 12 columns.

Tip: you may need to add

<link rel="stylesheet" href="http://getbootstrap.com.vn/examples/equal-height-columns/equal-height-columns.css" />

to your html


flexbox-based. Does not work in IE8 or 9, nor Android 2.x caniuse.com/#feat=flexbox
Note: getbootstrap.vn is not "Bootstrap". It's a 3rd party project.
This seems to be integrated in bootstrap v4 though.
I included the correct CSS (from the .vn site) but it messes everything up. it's based on flex
Great...plugin hell.

To answer your question this is all you need see full responsive demo with prefixed css:

/* Using col-xs media query breakpoint but you can change 481 to 768 to only apply to col-sm and above if you'd like*/

@media only screen and (min-width : 481px) {
    .flex-row {
        display: flex;
        flex-wrap: wrap;
    }
    .flex-row > [class*='col-'] {
        display: flex;
        flex-direction: column;
    }
    .flex-row.row:after, 
    .flex-row.row:before {
        display: flex;
    }
}

https://i.stack.imgur.com/NOlns.png

To add support for thumbnail content flex within flex columns like the screenshot above also add this... Note you could do this with panels as well:

.flex-row .thumbnail,
.flex-row .caption {
    display: flex;
    flex: 1 0 auto;
    flex-direction: column;
}
.flex-text {
    flex-grow: 1;
}    
.flex-row img {
    width: 100%;
}

While flexbox doesn't work in IE9 and below you can use the demo with a fallback using conditional tags with something like javascript grids as a polyfill:

<!--[if lte IE 9]>

<![endif]-->

As for the other two examples in the accepted answer... The table demo is a decent idea but is being implemented wrong. Applying that CSS on bootstrap column classes specifically will without a doubt break the grid framework entirely. You should be using a custom selector for one and two the tables styles should not be applied to [class*='col-'] that have defined widths. This method should ONLY be used if you want equal height AND equal width columns. It is not meant for any other layouts and is NOT responsive. We can make it fallback however on mobile displays...

<div class="table-row-equal">
<div class="thumbnail">
    Content...
</div>
<div class="thumbnail">
    Content...
</div>
</div>
@media only screen and (min-width : 480px){
    .table-row-equal {
        display: table;
        width: 100%;
        table-layout: fixed;
        border-spacing: 30px 0px;
        word-wrap: break-word;
    }
    .table-row-equal .thumbnail {
        float: none;
        display: table-cell;
        vertical-align: top;
        width: 1%;
    }
}

Lastly, the first demo in the accepted answer which implements a version of the one true layout is a good choice for some situations, but not suitable for bootstrap columns. The reason for this is that all the columns expand to the container height. So this will also break responsiveness since the columns are not expanding to the elements next to them, but the entire container. This method will also not allow you to apply bottom margins to rows any longer and will also cause other issues along the way like scrolling to anchor tags.

For the complete code see the Codepen which automatically prefixes the flexbox code.


That is the only one answer that actually worked for me. The 3 top rated answers were just a waste of time
Looks good, but unfortunately it doesn't work in Safari 9.1 on MacOS :-(
@TheSchecke here is the fix. As far as I know this works in all flexbox supported browsers now. Please let me know if I'm wrong. s.codepen.io/bootstrapped/debug/pboJNd. The problem had to do with the row:after, row:before having display: table set which apparently Safari doesn't like.
Just a heads up that this breaks really badly on the iPad's Safari browser
Sorry to hear that @MatthewLock. I just tested on my IPad Air IOS 8.1 with latest safari and it works on that. I was also able to test on on crossbrowsertesting.com using iPad mini retina with Safari 7 and that seems to be working fine too. Here's the results of that test. Can you provide the iPad and Safari version you are using? I'd love to try to get this fixed asap or at least put a comment in the answer as I know a lot of people are using it.

You only show one row so your use case may be limited to just that. Just in case you have multiple rows, this plugin - github Javascript-grids - works perfectly! It makes each panel expand to the tallest panel, giving each row potentially a different height based on the tallest panel in that row. It's a jquery solution vs. css, but wanted to recommend it as an alternative approach.


The only solution that really works and it doesn't break responsiveness
Does this allow you to specify that the columns should be square - or just all the same height?
@niico 14 - its been awhile since I've used this, but in my application the requirement is that the elements in each row were the same height, but the height might vary from row to row. Since the height is a function of the elements in the row, if your element height is equal to their width, then they should present as squares.

If you want to make this work in any browser, use javascript:

$( document ).ready(function() {
    var heights = $(".panel").map(function() {
        return $(this).height();
    }).get(),

    maxHeight = Math.max.apply(null, heights);

    $(".panel").height(maxHeight);
});

Have one div class="row" with variable number of panels each of class "col-md-4" which should give me 3 columns and unknown number of rows, depending on number of items I want to list. This JS worked and requires minimal change in my HTML/CSS, as opposed to various CSS thingies I tried. Only thing I changed was to mark all my column panels with additional class, i.e. "same-height-panel" and then use $(".same-height-panel") instead of $(".panel")
The only solution that worked for me after one day of experimenting with css stuff.
This is a good solution, but .ready() is not the right time to call it - it should be called on .load()
@jave.web If you think that this is a good solution, please give it a thumbs up. Thanks
Use window.onload = function() {...function content above...} instead. This works better.

I tried alot of the suggestions made in this thread and on other pages but no solution worked 100% in every browsers.

So I experimented quite some time and came up with this. A complete solution for Bootstrap Equal Height columns with the help of flexbox with only 1 class. This works in all major browsers IE10+.

CSS:

.row.equal-cols {
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-flex-wrap: wrap;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
}

.row.equal-cols:before,
.row.equal-cols:after {
  display: block;
}

.row.equal-cols > [class*='col-'] {
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-flex-direction: column;
  -ms-flex-direction: column;
  flex-direction: column;
}

.row.equal-cols > [class*='col-'] > * {
  -webkit-flex: 1 1 auto;
  -ms-flex: 1 1 auto;
  flex: 1 1 auto; 
}

HTML:

<div class="container">
  <div class="row equal-cols">
    <div class="col-sm-4">
      <div class="content"></div>
    </div>
    <div class="col-sm-4">
      <div class="content"></div>
    </div>
    <div class="col-sm-4">
      <div class="content"></div>
    </div>
  </div>
</div>

To support even more versions of IE you can, for example, use https://github.com/liabru/jquery-match-height and target all child columns of .equal-cols. Like this:

// Create a check for IE9 (or any other specific browser).
if(IE9) {
  $(".row.equal-cols > [class*='col-']").matchHeight();
}

Without this polyfill the columns will behave as usual Bootstrap columns so which is a quite good fallback.

From official documentation. Maybe you can use it in your case.

When you need equal height, add .h-100 to the cards.

<div class="row row-cols-1 row-cols-md-3 g-4">
  <div class="col">
   <div class="card h-100">
     <div>.....</div>
  </div>
  <div class="col">
   <div class="card h-100">
     <div>.....</div>
  </div>

Steffan Perry

You can use inline-flex as well which works pretty good and may be a little cleaner than modifying every row element with CSS.

For my project I wanted every row who's child elements had borders to be the same height so the borders would look jagged. For this I created a simple css class.

.row.borders{
    display: inline-flex;
    width: 100%;
}

While it succeeds at making all the contents in the row the same height; This breaks the responsiveness of Bootstrap.

I'm surprised I couldn't find a worthwhile solution here late 2018. I went ahead and figured it out a Bootstrap 3 solution myself using flexbox.

Clean and simple example:

https://i.stack.imgur.com/M2be0.png

HTML

<div class="row row-equal">
    <div class="col-lg-4 col-md-4 col-sm-4 col-xs-12 col-equal">
        <p>Text</p>
    </div>
    <div class="col-lg-4 col-md-4 col-sm-4 col-xs-12 col-equal">
        <img src="//placehold.it/200x200">
    </div>
    <div class="col-lg-4 col-md-4 col-sm-4 col-xs-12 col-equal">
        <p>Text</p>
    </div>  
</div>

CSS

img {
  width: 100%;
}
p {
  padding: 2em;
}
@media (min-width: 768px) {
  .row-equal {
    display: flex;
    flex-wrap: wrap;
  }
  .col-equal {
    margin: auto;
  }
}

If anyone using bootstrap 4 and looking for equal height columns just use row-eq-height to parent div

.row.row-eq-height > .col-xs-4
.row.row-eq-height > .col-xs-4
this is
a much
taller
column
than the others
.row.row-eq-height > .col-xs-4

Ref: http://getbootstrap.com.vn/examples/equal-height-columns/


I think this would be the best answer

cheeky jquery solution if anyone's interested. Just make sure all your cols (el) have a common classname...works responsively too if you bind it to $(window).resize

function equal_cols(el)
{
    var h = 0;
    $(el).each(function(){
        $(this).css({'height':'auto'});
        if($(this).outerHeight() > h)
        {
            h = $(this).outerHeight();
        }
    });
    $(el).each(function(){
        $(this).css({'height':h});
    });
}

Usage

$(document).ready(function(){
   equal_cols('.selector');
});

Note: This post has been edited as per @Chris' comment out that the code was only set the last highest height in the $.each() function


This is understated - simple and small yet will resize all columns without needing to have a fixed number of columns in a row. Nice one!
This isn't working, cause you set the last biggest height in the each function. If the third column is the highest column, column 1 and 2 aren't getting the right height.. You have to set the last line "$(this).css({'height':h});" after the each function. I will do an edit.

Some of the previous answers explain how to make the divs the same height, but the problem is that when the width is too narrow the divs won't stack, therefore you can implement their answers with one extra part. For each one you can use the CSS name given here in addition to the row class that you use, so the div should look like this if you always want the divs to be next to each other:

<div class="row row-eq-height-xs">Your Content Here</div>

For all screens:

.row-eq-height-xs {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: row;
}

For when you want to use sm:

.row-eq-height-sm {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: column;
}
@media (min-width:768px) {
    .row-eq-height-sm {
        flex-direction: row;
    }
}

For when you want to md:

.row-eq-height-md {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: column;
}
@media (min-width:992px) {
    .row-eq-height-md {
        flex-direction: row;
    }
}

For when you want to use lg:

.row-eq-height-lg {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display:         flex;
    flex-direction: column;
}
@media (min-width:1200px) {
    .row-eq-height-md {
        flex-direction: row;
    }
}

EDIT Based on a comment, there is indeed a simpler solution, but you need to make sure to give column info from the largest desired width for all sizes down to xs (e.g. <div class="col-md-3 col-sm-4 col-xs-12">:

.row-eq-height {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
    flex-direction: row;
    flex-wrap: wrap;
}

You made that a lot more complicated than you needed to :) ` Just use flex-wrap: wrap; then you don't need all the separate ones... unless you specifically want them.

I know I'm very late but now you can use the "min-height" style attribute to achieve your purpose.

So yes, Bootstrap 4 does make all the cols in a row equal height, however if you are creating a border around the content inside the row you may find that it appears like the cols are not equal heights!

When I applied height: 100% to the element inside the col I found that I lost my margin.

My solution is to use padding on the col's div (instead of a margin on the inner element). Like so:

<div class="container">
    <div class="row">
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
        <div class="col-lg-4 col-md-6 col-12 py-4">
            <div class="h-100 border round">
                        ...
            </div>
        </div>
    </div>
</div>

The above code example uses Bootstrap 4.1 to create a set of nine boxes with a border


D
DarkScrolls
.row.container-height {
    overflow: hidden;
}

.row.container-height>[class*="col-"] {
    margin-bottom: -99999px;
    padding-bottom: 99999px;
}

where .container-height is the style class that has to be added to a .row styled element to which all its .col* children have the same height.

Applying these styles only to some specific .row (with .container-height, as in the example) also avoids applying the margin and padding overflow to all .col*.

here is my solution (compiled CSS):

.row.row-xs-eq {
  display: table;
  table-layout: fixed;
  margin: 0;
}

.row.row-xs-eq::before {
  content: none;
}

.row.row-xs-eq::after {
  content: none;
}

.row.row-xs-eq > [class^='col-'] {
  display: table-cell;
  float: none;
  padding: 0;
}

@media (min-width: 768px) {
  .row.row-sm-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-sm-eq::before {
    content: none;
  }

  .row.row-sm-eq::after {
    content: none;
  }

  .row.row-sm-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

@media (min-width: 992px) {
  .row.row-md-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-md-eq::before {
    content: none;
  }

  .row.row-md-eq::after {
    content: none;
  }

  .row.row-md-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

@media (min-width: 1200px) {
  .row.row-lg-eq {
    display: table;
    table-layout: fixed;
    margin: 0;
  }

  .row.row-lg-eq::before {
    content: none;
  }

  .row.row-lg-eq::after {
    content: none;
  }

  .row.row-lg-eq > [class^='col-'] {
    display: table-cell;
    float: none;
    padding: 0;
  }
}

So your code would look like:

<div class="row row-sm-eq">
  <!-- your old cols definition here -->
</div>

Basically this is the same system you use with .col-* classes with that difference you need to apply .row-* classes to the row itself.

With .row-sm-eq columns will be stacked on XS screens. If you don't need them to be stacked on any screens you can use .row-xs-eq.

The SASS version that we do actually use:

.row {
  @mixin row-eq-height {
    display: table;
    table-layout: fixed;
    margin: 0;

    &::before {
      content: none;
    }

    &::after {
      content: none;
    }

    > [class^='col-'] {
      display: table-cell;
      float: none;
      padding: 0;
    }
  }

  &.row-xs-eq {
    @include row-eq-height;
  }

  @media (min-width: $screen-sm-min) {
    &.row-sm-eq {
      @include row-eq-height;
    }
  }

  @media (min-width: $screen-md-min) {
    &.row-md-eq {
      @include row-eq-height;
    }
  }

  @media (min-width: $screen-lg-min) {
    &.row-lg-eq {
      @include row-eq-height;
    }
  }
}

Live demo

Note: mixing .col-xs-12 and .col-xs-6 inside a single row would not work properly.


This is good. My solution is the same. And there is a possibility to have equal height columns with standard Bootstrap's 30px gaps between columns using border-spacing and negative margins.

Станислав Пономарев

There is a problem with using Solution 1 while appling it on only column in rows. Would like to improve Solution 1.

 [class^="col-"]:not([class*="-12"]){
      margin-bottom: -99999px;
      padding-bottom: 99999px;
  }

For those looking for a quick, easy solution - if you have a relatively consistent set of block content setting a min-height on the div that is a bit bigger than the largest block can be easier to implement.

.align-box {
    min-height: 400px;
}

Ajay Sathish

Here is my method, i have used flex with some changes in media query.

  @media (min-width: 0px) and (max-width: 767px) {
  .fsi-row-xs-level {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
  }
}
@media (min-width: 768px) and (max-width: 991px) {
  .fsi-row-sm-level {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
  }
}
@media (min-width: 992px) and (max-width: 1199px) {
  .fsi-row-md-level {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
  }
}
@media (min-width: 1200px) {
  .fsi-row-lg-level {
    display: -webkit-box;
    display: -webkit-flex;
    display: -ms-flexbox;
    display: flex;
  }
}

then added the classes to the parent which were required.

<div class="row fsi-row-lg-level fsi-row-md-level">
<div class="col-sm-4">column 1</div>
<div class="col-sm-4">column 2</div>
<div class="col-sm-4">column 3</div>
</div>

I am using responsive breakpoints because flux usually hampers the bootstrap standard responsive nature.

Oleg

I use this super easy solution with clearfix, which doesn't have any side effects.

Here is an example on AngularJS:

<div ng-repeat-start="item in list">
    <div class="col-lg-4 col-md-6 col-sm-12 col-xs-12"></div>
</div>
<div ng-repeat-end>
    <div ng-if="$index % 3 == 2" class="clearfix visible-lg"></div>
    <div ng-if="$index % 2 == 1" class="clearfix visible-md"></div>
</div>

And one more example on PHP:

<?php foreach ($list as $i => $item): ?>
    <div class="col-lg-4 col-md-6 col-sm-12 col-xs-12"></div>
    <div class="clearfix visible-md"></div>
    <?php if ($i % 2 === 1): ?>
        <div class="clearfix visible-lg"></div>
    <?php endif; ?>
<?php endforeach; ?>

This does not make your columns all the same height, though.
For me wanting to have columns at the same height/place in row it is a solution
k

I searched for a solution to the same problem, and found one just worked !! - with almost no extra code..

see https://medium.com/wdstack/bootstrap-equal-height-columns-d07bc934eb27 for a good disuccuion, and with the resposne you want in the bottom, with a link.

https://www.codeply.com/go/EskIjvun4B

this was the correct responsive way to for me... a quote: ... 3 — Use flexbox (best!)

As of 2017, the best (and easiest) way to make equal height columns in a responsive design is using CSS3 flexbox.

.row.display-flex {
  display: flex;
  flex-wrap: wrap;
}
.row.display-flex > [class*='col-'] {
  display: flex;
  flex-direction: column;
}

and simply use:

div class="container">
   <div class="row display-flex .... etc..

@media (min-width: @screen-sm-min) {
    div.equal-height-sm {
        display: table;


        > div[class^='col-'] {
            display: table-cell;

Example:

https://jsfiddle.net/b9chris/njcnex83/embedded/result/

Adapted from several answers here. The flexbox-based answers are the right way once IE8 and 9 are dead, and once Android 2.x is dead, but that is not true in 2015, and likely won't be in 2016. IE8 and 9 still make up 4-6% of usage depending on how you measure, and for many corporate users it's much worse. http://caniuse.com/#feat=flexbox

The display: table, display: table-cell trick is more backwards-compatible - and one great thing is the only serious compatibility issue is a Safari issue where it forces box-sizing: border-box, something already applied to your Bootstrap tags. http://caniuse.com/#feat=css-table

You can obviously add more classes that do similar things, like .equal-height-md. I tied these to divs for the small performance benefit in my constrained usage, but you could remove the tag to make it more generalized like the rest of Bootstrap.

Note that the jsfiddle here uses CSS, and so, things Less would otherwise provide are hard-coded in the linked example. For example @screen-sm-min has been replaced with what Less would insert - 768px.

VishAl

If it makes sense in your context, you can simply add an empty 12-column div after each break, which acts as a divider that hugs the bottom of the tallest cell in your row.

Thought I'd just add that the answer given by Dr.Flink can also be applied to a Bootstrap 3 form-horizontal block - which can be very handy if you want to use background colours for each cell. In order for this to work for bootstrap forms, you would need to wrap the form contents which just serves to replicate a table-like structure.

The example below also provides the CSS which demonstrates an additional media query allows Bootstrap 3 to simply takeover and do it's normal thing on the smaller screen(s). This also works in IE8+ .

Example:

<form class="form-horizontal" role="form">

  <div class="form-wrapper">
    <div class="form-group">
      <label class="col-xs-12 col-sm-2 control-label">My Label</label>
      <div class="col-xs-12 col-sm-10">
        Some content
      </div>
    </div>
  </div>

</form>
.form-wrapper {
  display: table;
}

.form-wrapper .form-group {
  display: table-row;
}

.form-wrapper .form-group .control-label {
  display: table-cell;
  float: none;
}

.form-wrapper .form-group label + div {
  display: table-cell;
  float: none;
}

@media (max-width: 768px) {
  .form-wrapper {
    display: inherit;
  }
  .form-wrapper .form-group {
    display: block;
  }
  .form-wrapper .form-group .control-label {
    display: inherit;
  }
  .form-wrapper .form-group label + div {
    display: inherit;
  }
}

You can wrap the columns inside a div

<div class="row">
<div class="col-md-12>
  <div class="col-xs-12 col-sm-4 panel" style="background-color: red">
  some content
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: yellow">
  kittenz
  <img src="http://placekitten.com/100/100">
  </div>
  <div class="col-xs-6 col-sm-4 panel" style="background-color: blue">
  some more content
  </div>
</div>
</div>

Did not work for me with a button in one of the columns.
