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

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

Answer 2

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>

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.

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;
  }
}

Answer 5

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.

Answer 6

Try this do through flex-box

.container {
	display: flex;
	padding-bottom: 50px;
}
.col {
	background: blue;
	padding: 30px;
}

.col.center {
	background: red;
	height: 100px;
	margin-bottom: -50px;
}

<div class="container">
  <div class="col">Left</div>
  <div class="col center">Center</div>
  <div class="col">Right</div>
</div>
