Use the .row class to structure your content into vertically stacked sections.

The .row class can be combined with two more classes which will lead to different behavior of the row itself:

  • .row.full Expands the row to the full width of the viewport
  • .row.collapse Collapses all columns contained in the specific row and sets their horizontal spacing to zero.

Of course both classes can be combined to build a full-width collapsed row.
