What is grid system and list some grid classes?
The Bootstrap grid System has a limit of 12 columns across the entire page. If a developer does not want to use the 12 columns individually then, it can be merged to create a more full column.
The grid system has the following four classes-
- xs (for the phones - screens less than 768px wide)
- sm (for the tablets - screens equal to or greater than 768px wide)
- md (for the small laptops - screens equal to or greater than 992px wide)
- lg (for the laptops and the desktops - screens equal to or greater than 1200px wide)
