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).
