Add another grid to nest within an existing column.
The grid system has 5 tiers of classes - xs (phones), sm (tablets), md (desktops), lg (larger desktops) and xl (even larger desktops). You can use nearly any combination of these classes to create more dynamic and flexible layouts.
Each tier of classes scales up, meaning if you plan on setting the same widths for xs and sm, you only need to specify xs.
The grid can be used to create fully fluid forms
