Grid-Example
Using a single set of .col-sm-*
classes, you can create a basic grid system that starts out stacked on extra small devices before becoming horizontal on desktop (medium) devices.
Max-Auto (Offset)
Move columns to the right using .offset-md-*
classes. These classes increase the left margin of a column by * columns. For example, .offset-md-4
moves .col-md-4
over four columns. With the move to flexbox in v4, you can use margin utilities like .mr-auto
to force sibling columns away from one another.
Nested Grid
To nest your content with the default grid, add a new .row
and set of .col-sm-*
columns within an existing .col-sm-*
column. Nested rows should include a set of columns that add up to 12 or fewer (it is not required that you use all 12 available columns).
