This module describes multi-column layout in CSS. By using
functionality described in this document, style sheets can declare that
the content of an element is to be laid out in multiple columns.

On the Web, tables have also been used to describe multi-column
layouts. The main benefit of using CSS-based columns is flexibility;
content can flow from one column to another, and the number of columns
can vary depending on the size of the viewport. Removing presentation
table markup from documents allows them to more easily be presented on
various output devices including speech synthesizers and small mobile
devices.
