Columns grid
We apply a wide and narrow layout format. In the wide layout format (1200px width), the page contents may employ up to 4 columns and use a margin of 24px.
In the narrow layout format (750px width) the page contents may employ up to 2 columns.
Column width uses percentages, rather than fixed values.
Gutters, or the spaces between columns, use a fixed value (24px).
