Bootstrap 4 Grid Extra Small
Extra Small Grid Example
| Extra small | Small | Medium | Large | Extra Large | |
|---|---|---|---|---|---|
| Class prefix | .col- |
.col-sm- |
.col-md- |
.col-lg- |
.col-xl- |
| Screen width | <576px | >=576px | >=768px | >=992px | >=1200px |
Assume we have a simple layout with two columns. We want the columns to split 25%/75% for ALL devices.
We will add the following classes to our two columns:
<div class="col-9">....</div>
The following example will result in a 25%/75% split on all devices (extra small, small, medium, large and xlarge).
Example
<div class="row">
<div class="col-3 bg-success">
<p>Lorem ipsum...</p>
</div>
<div class="col-9 bg-warning">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
Note: Make sure that the sum adds up to 12 or fewer (it is not required that you use all 12 available columns):
For a 33.3%/66.6% split, you would use .col-4 and .col-8 (and for a 50%/50% split, you would use .col-6 and .col-6):
Example
<div class="container-fluid">
<div class="row">
<div class="col-4 bg-success">
<p>Lorem ipsum...</p>
</div>
<div class="col-8 bg-warning">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
<!-- 50%/50% split -->
<div class="container-fluid">
<div class="row">
<div class="col-6 bg-success">
<p>Lorem ipsum...</p>
</div>
<div class="col-6 bg-warning">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
Auto Layout Columns
In Bootstrap 4, there is an easy way to create equal width columns for all devices: just remove the number from .col-* and only use the .col class on a specified number of
col elements. Bootstrap will recognize how many columns there are, and each column will get the same width:
<div class="row">
<div class="col">1 of 2</div>
<div class="col">2 of 2</div>
</div>
<!-- Four columns: 25% width-->
<div class="row">
<div class="col">1 of 4</div>
<div class="col">2 of 4</div>
<div class="col">3 of 4</div>
<div class="col">4 of 4</div>
</div>
