Bootstrap Grid System

Bootstrap’s grid system allows up to 12 columns across the page.

If you do not want to use all 12 columns individually, you can group the columns together to create wider columns:

span 1 span 1 span 1 span 1 span 1 span 1 span 1 span 1 span 1 span 1 span 1 span 1
 span 4  span 4  span 4
span 4 span 8
span 6 span 6
span 12

Bootstrap’s grid system is responsive, and the columns will re-arrange automatically depending on the screen size.

Grid Classes

The Bootstrap grid system has four classes:

  • xs (for phones)
  • sm (for tablets)
  • md (for desktops)
  • lg (for larger desktops)

The classes above can be combined to create more dynamic and flexible layouts.

Three Equal Columns

.col-sm-4
.col-sm-4

The following example shows how to get a three equal-width columns starting at tablets and scaling to large desktops. On mobile phones, the columns will automatically stack:

Example
