Bootstrap Grid - Small Devices
Bootstrap Grid Example: Small Devices
| Extra small | Small | Medium | Large | |
|---|---|---|---|---|
| Class prefix | .col-xs |
.col-sm |
.col-md |
.col-lg |
| Screen width | <768px | >=768px | >=992px | >=1200px |
Assume we have a simple layout with two columns. We want the columns to be split 25%/75% for small devices.
Tip: Small devices are defined as having a screen width from 768 pixels to 991 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>
<div class="col-sm-9">....</div>
Now Bootstrap is going to say "at the small size, look for classes with -sm- in them and use those".
The following example will result in a 25%/75% split on small (and medium and large) devices. On extra small devices, it will automatically stack (100%):
col-sm-3
col-sm-9
Example
<div class="container-fluid">
<h1>Hello World!</h1>
<div class="row">
<div class="col-sm-3" style="background-color:yellow;">
<p>Lorem ipsum...</p>
</div>
<div class="col-sm-9" style="background-color:pink;">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
Try it Yourself » <h1>Hello World!</h1>
<div class="row">
<div class="col-sm-3" style="background-color:yellow;">
<p>Lorem ipsum...</p>
</div>
<div class="col-sm-9" style="background-color:pink;">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
Note: Make sure that the sum always adds up to 12.
For a 33.3%/66.6% split, you would use .col-sm-4 and .col-sm-8:
col-sm-4
col-sm-8
Example
<div class="container-fluid">
<h1>Hello World!</h1>
<div class="row">
<div class="col-sm-4" style="background-color:yellow;">
<p>Lorem ipsum...</p>
</div>
<div class="col-sm-8" style="background-color:pink;">
<p>Sed ut perspiciatis...</p>
</div>
</div>
</div>
