Specification

https://drafts.csswg.org/css-multicol-2

Summary

Add support for the `column-wrap` and `column-height` CSS properties, from multicol Level 2. https://drafts.csswg.org/css-multicol-2/#cwr https://drafts.csswg.org/css-multicol-2/#ch This allows for vertical column layout, or even 2D column layout. Columns can have an explicit constrained height, apart from being derived from the content-box height of the multicol container, and wrap to a new row of columns when all columns have been filled for one row, rather than creating overflowing columns in the inline direction.
