How Does Bootstrap work?

When a web designer designs a website with Bootstrap, then he does not need to do much coding because many codes are already given in Bootstrap which are only reused on the HTML page.

Bootstrap has many predefined classes of CSS that can be easily used by calling them on your page.

Bootstrap works on a grid system that divides the entire page into equal columns and rows. Different CSS classes have been created for all the rows and columns which can be used on your web page as per the need.
