Bootstrap 4 Grid Stacked-to-horizontal


Bootstrap 4 Grid Example: Stacked-to-horizontal

We will create a basic grid system that starts out stacked on extra small devices, before becoming horizontal on larger devices.

The following example shows a simple "stacked-to-horizontal" two-column layout, meaning it will result in a 50%/50% split on all screens, except for extra small screens, which it will automatically stack (100%):

col-sm-6
col-sm-6

Example: Stacked-to-horizontal

<div class="container">
  <div class="row">
    <div class="col-sm-6 bg-success">
      <p>Lorem ipsum...</p>
    </div>
    <div class="col-sm-6 bg-warning">
      <p>Sed ut perspiciatis...</p>
    </div>
  </div>
</div>

Tip: The numbers in the .col-sm-* classes indicates how many columns the div should span (out of 12). So, .col-sm-1 spans 1 column, .col-sm-4 spans 4 columns, .col-sm-6 spans 6 columns, etc.

Note: Make sure that the sum adds up to 12 or fewer (it is not required that you use all 12 available columns):

Tip: You can turn any fixed-width layout into a full-width layout by changing the .container class to .container-fluid:

Example: Fluid container

<div class="container-fluid">
  <div class="row">
    <div class="col-sm-6">
      <p>Lorem ipsum...</p>
    </div>
    <div class="col-sm-6">
      <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-size-* and only use the .col-size class on a specified number of col elements. Bootstrap will recognize how many columns there are, and each column will get the same width. The size classes determines when the columns should be responsive:

<!-- 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>
1 of 2
2 of 2
1 of 4
2 of 4
3 of 4
4 of 4
