One benefit of using Bootstrap is that it incorporates responsive design. With responsive design, the layout of the content changes to accommodate a user’s screen size.
Bootstrap categorizes screen sizes into 5 categories or as breakpoints: extra small, small, medium, large, and extra large. Each breakpoint has a range measured in pixels. The range of these breakpoints and accompanying device types are marked in the following table:
By using these breakpoints in combination with Bootstrap’s grid, we can customize the layout of our content for different screens.
