Bootstrap 5 Grid System
Bootstrap's grid system is built with flexbox and allows up to 12 columns across the page.
If you do not want to use all 12 columns individually, you can group the columns together to create wider columns:
| span 1 | span 1 | span 1 | span 1 | span 1 | span 1 | span 1 | span 1 | span 1 | span 1 | span 1 | span 1 |
| span 4 | span 4 | span 4 | |||||||||
| span 4 | span 8 | ||||||||||
| span 6 | span 6 | ||||||||||
| span 12 | |||||||||||
The grid system is responsive, and the columns will re-arrange automatically depending on the screen size.
Make sure that the sum adds up to 12 or fewer (it is not required that you use all 12 available columns).
Grid Classes
The Bootstrap 5 grid system has six classes:
.col-(extra small devices - screen width less than 576px).col-sm-(small devices - screen width equal to or greater than 576px).col-md-(medium devices - screen width equal to or greater than 768px).col-lg-(large devices - screen width equal to or greater than 992px).col-xl-(xlarge devices - screen width equal to or greater than 1200px).col-xxl-(xxlarge devices - screen width equal to or greater than 1400px)
Three Equal Columns
Example
The following example shows how to create three equal-width columns, on all devices and screen widths:
<div class="row">
<div class="col">.col</div>
<div class="col">.col</div>
<div
class="col">.col</div>
</div>
Responsive Columns
Example
<div class="row">
<div
class="col-sm-3">.col-sm-3</div>
<div
class="col-sm-3">.col-sm-3</div>
<div
class="col-sm-3">.col-sm-3</div>
<div class="col-sm-3">.col-sm-3</div>
</div>
Two Unequal Responsive Columns
The following example shows how to get two various-width columns starting at tablets and scaling to large extra desktops:
Example
<div class="row">
<div class="col-sm-4">.col-sm-4</div>
<div class="col-sm-8">.col-sm-8</div>
</div>
