Bootstrap 5 Grid Small
Small Grid Example
| XSmall | Small | Medium | Large | Extra Large | XXL | |
|---|---|---|---|---|---|---|
| Class prefix | .col- |
.col-sm- |
.col-md- |
.col-lg- |
.col-xl- |
.col-xxl- |
| Screen width | <576px | >=576px | >=768px | >=992px | >=1200px | >=1400px |
Assume we have a simple layout with two columns. We want the columns to be split 25%/75% for small devices.
Small devices are defined as having a screen width from 576 pixels to 767 pixels.
For small devices we will use the .col-sm-* classes.
We will add the following classes to our two columns:
<div class="col-sm-3">....</div>
<div class="col-sm-9">....</div>
The following example will result in a 25%/75% split on small (and medium, large, xlarge and xxlarge) devices. On extra small devices, it will automatically stack (100%):
Example
<div class="container-fluid">
<div class="row">
<div class="col-sm-3 bg-primary">
<p>Lorem ipsum...</p>
</div>
<div class="col-sm-9 bg-dark">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
Try it Yourself »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-sm-4 and .col-sm-8 (and for a 50%/50% split, you would use .col-sm-6 and .col-sm-6):
Example
<!-- 33.3/66.6% split: -->
<div class="container-fluid">
<div class="row">
<div class="col-sm-4 bg-primary">
<p>Lorem ipsum...</p>
</div>
<div class="col-sm-8 bg-dark">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
<!-- 50%/50% split: -->
<div class="container-fluid">
<div class="row">
<div class="col-sm-6 bg-primary">
<p>Lorem ipsum...</p>
</div>
<div class="col-sm-6 bg-dark">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
Try it Yourself »Auto Layout Columns
In Bootstrap 5, there is an easy way to create equal width columns for all devices: just remove the number from .col-sm-* and only use the .col-sm class on a specified number of
col elements. Bootstrap will recognize how many columns there
are, and each column will get the same width.
If the screen size is less than 576px, the columns will stack horizontally:
<!-- Two columns: 50% width on all screens, except for extra small (100%
width) -->
<div class="row">
<div class="col-sm">1 of
2</div>
<div class="col-sm">2 of 2</div>
</div>
<!-- Four
columns: 25% width on all screens, except for extra small (100% width)-->
<div class="row">
<div class="col-sm">1 of 4</div>
<div class="col-sm">2 of 4</div>
<div class="col-sm">3
of 4</div>
<div class="col-sm">4 of 4</div>
</div>
The next chapter shows how to add a different split percent for medium devices.
