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>

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;
}

Update 2018

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):

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.

1) Using huge negative margins & padding

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

Bootstrap 4

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

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
