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-3">....</div>
<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).

col-3
col-9

Example

<div class="container-fluid">
  <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):

col-4
col-8
col-6
col-6

Example

<!-- 33.3%/66.6% split -->
<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:

<!-- Two columns: 50% 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>
1 of 2
2 of 2
1 of 4
2 of 4
3 of 4
4 of 4
