Bootstrap 5 Grid System Options is a responsive grid system that allows you to create flexible and dynamic layouts for your website. The grid system options are flexible enough to respond to both the six built-in breakpoints and any custom ones.
Grid System Options Classes:
- .col: This is the base class for all grid columns. It is used to set the width of a column and the breakpoint at which it will become full width.
- .col-xs: This class is used for the extra small device(screen widths less than 576px).
- .col-sm: This class is used for small devices (screen widths equal to or greater than 576px).
- .col-md: This class is used for medium devices (screen widths equal to or greater than 768px).
- .col-lg: This class is used for large devices (screen widths equal to or greater than 992px).
- .col-xl: This class is used for extra large devices (screen widths equal to or greater than 1200px).
- .col-xxl: This class is used for extra large devices (screen widths equal to or greater than 1400px).
Syntax:
<div class="col-[breakpoint]-[width] [other-classes]">
...
</div> Where,
- breakpoint: is the name of the breakpoint, such as sm, md, lg, xl, or xxl.
- width: the number of columns that the element should occupy at the specified breakpoint.
- other-classes: This denotes any other classes that you want to add to the element.
Example1:In this example, we have a container element that holds a row with three columns. Here’s a breakdown of the Bootstrap grid classes used:
- col-lg-4: The first and second columns will take 4 grid columns each on large screens and above.
- col-md-6: The first and second columns will take 6 grid columns each on medium screens.
- col-sm-12: The first and second columns will take 12 grid columns each on small screens and below.
- col-lg-4 col-md-12 col-sm-12: The third column will take 4 grid columns on large screens and above, and 12 grid columns on medium and small screens.

Output:
Example 2: In this example, we have used the Bootstrap 5 grid system to create a layout with different column options.
- The first row contains three columns, each taking equal space (col class).
- The second row contains two half-width columns on medium-sized screens and larger (col-md-6 class).
- The third row contains three one-third-width columns on large screens and larger (col-lg-4 class).
