Grid System Bootstrap
Bootstrap includes a responsive, mobile first fluid grid system that appropriately scales up to 12 columns as the device or viewport size increases. It includes predefined classes for easy layout options, as well as powerful mixins for generating more semantic layouts.
The Bootstrap grid system has four classes:
- xs (for phones)
- sm (for tablets)
- md (for desktops)
- lg (for larger desktops)
