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.

Offset (Max-Auto)
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.
