One question that's been raised about CSS Regions is where the boxes for
the region chain come from. There are some who would like to define the
box in CSS rather than add an element to the HTML markup. Pseudo-elements
can define the box in CSS, so we're using that capability. So you'd want
to use pseudo-elements for region chain boxes if you want to keep
presentational elements out of your semantic HTML.

Thanks,
