How can I make Bootstrap columns all the same heig

Question

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:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid">
<div class="row">
    <div class="col-xs-4 panel" style="background-color: red">
        some content
    </div>
    <div class="col-xs-4 panel" style="background-color: yellow">
        catz
        <img width="100" height="100" src="https://lorempixel.com/100/100/cats/">
    </div>
    <div class="col-xs-4 panel" style="background-color: blue">
        some more content
    </div>
</div>
</div>

Answer 1

HTML

<div class="container-fluid">
<div class="row-fluid">
<div class="span4 option2">
<p>left column </p>
<p>The first column has to be the longest The first column has to be the longes</p>
</div>

<div class="span4 option2">
<p>middle column</p>
</div>

<div class="span4 option2">
<p>right column </p>
<p>right column </p>
<p>right column </p>
<p>right column </p>
<p>right column </p>
</div>
</div>
</div>

CSS

.option2 { background: red; border: black 1px solid; color: white; }

JS

$('.option2').css({
    'height': $('.option2').height()
});

Answer 2

Just checking through bootstrap documentation and I found the simple solution for the problem of column same height.

Add the extra clearfix for only the required viewport

<div class="clearfix visible-xs-block"></div>

For example:

<div class="col-md-3 col-xs-6">This is a long text</div>
<div class="col-md-3 col-xs-6">This is short</div>
<div class="clearfix visible-xs-block">This is a long text</div>
<div class="col-md-3 col-xs-6">Short</div>
<div class="col-md-3 col-xs-6">Long Text</div>
<div class="clearfix visible-xs-block"></div>
<div class="col-md-3 col-xs-6">Longer text which will push down</div>
<div class="col-md-3 col-xs-6">Short</div>

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;
  }

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);
});

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

  <link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-beta.2/css/bootstrap.min.css" rel="stylesheet"/>
    <div class="row row-eq-height">
            <div class="col-xs-4" style="border: 1px solid grey;">.row.row-eq-height &gt; .col-xs-4</div>
            <div class="col-xs-4" style="border: 1px solid grey;">.row.row-eq-height &gt; .col-xs-4<br>this is<br>a much<br>taller<br>column<br>than the others</div>
            <div class="col-xs-4" style="border: 1px solid grey;">.row.row-eq-height &gt; .col-xs-4</div>
          </div>

Answer 6

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;
}
