Grid

Start by adding an element with a class of .grid. This will create a horizontal block to contain vertical columns. Then add elements with a .grid__col class within that row. Specify the widths of each column with .grid__col--xs-#, .grid__col--sm-#, .grid__col--md-# and .grid__col--lg-# classes. Responsive modifiers enable specifying different column sizes, offsets, alignment and distribution at xs, sm, md & lg viewport widths. Bare in mind that the layout is mobile-first, it has 24 columns without gutter. You can stack modifiers if you want to achieve different alignment depending on screen size.

Gutter

Add gutters to elements with .grid__col--gutter-xs-#, .grid__col--gutter-sm-#, .grid__col--gutter-md-# and .grid__col--gutter-lg-#
