Grid system Grid tiers

Across the six default breakpoints, the grid works smoothly, and all these breakpoints can also be called Grid Tiers which can be changed using the SASS version. For this, we can use the $grid-breakpoints and $container-max-widths for changing the maximum width occupied by the container at the various breakpoints.

Variables needed to control Grid tiers and their default values:

• $grid-breakpoints: This variable states the grid tier values(screen sizes of the viewport) where the grid will break into the custom responsive number of columns if specified. Under this variable, the default values are 0 for xs, 576px for sm, 768px for md, 992px for lg, 1200px for xl, and 1400px for xxl.
• $container-max-widths: This variable states the maximum width of the container at any specific given breakpoint or viewport size. Under this variable, the default values are 0 for xs, 540px for sm, 720px for md, 960px for lg, 1140px for xl, and 1320px for xxl.

Syntax:

$variable_to_override: (
    /* Grid Tiers and their values */
) !default;

The Only Approach to customize the grid in Bootstrap that is by using the SASS version of it.

Bootstrap Grid system is one of the most versatile layouts which we can use and it has different responsive variants which can be used to add custom responsiveness. Bootstrap Grid system provides a responsive layout with columns and gutters. Customizing the grid is essentially changing the number of columns or gutters’ width or changing the breakpoints at which the grids will attain the specific width given to them.
