Grid System

Bootstrap Grid System

Bootstrap uses a Grid System having rows and columns

In the Grid system, you are using a row class to create a horizontal box with a total of 12 columns of size 1 unit each for different screen size vertically. If you do not want to use all 12 columns individually, you can group the columns together to create wider columns.

Example : if you want to make a row of 3 columns - you have a div with class=“row” (i.e one horizontal box) and 3 columns( class = col.xs.xx) each of size 3, size 2, size 7 ( 3+2+7 =12) for xs = extra small screen size of size
