Bootstrap 4: Grid System Cheat Sheet

One of the main concept of working with Bootstrap is the Grid system.  It could be intimidating at first to work with the Grid system.  But the system is quite elegant and simple solution.

The most important thing you have to remember about the grid system is that it divides the page into 12 columns, and it is responsive meaning it will adjust to the size of the client's screen.

You can control the size of the column with the .col-sm, .col-md, .col-lg, .col-xl, which translates to small, medium, large, and extra large screens.  In addition to the screen size you can also control the with of the column with the -n at the end of class attribute.  For example if you want a column for a small screen to span three columns it would be .col-sm-3.

Here is the cheat sheet, I am going to use color coding for the different sizes.

Small - Green
Medium - Orange
Large - Red
Extra Large - Blue
