The CSS Working Group has published the CSS Multi-column Layout Module Level 1 as a W3C Candidate Recommendation Snapshot. This specification describes multi-column layouts in CSS, a style sheet language for the web. Using functionality described in the specification, content can be flowed into multiple columns with a gap and a rule between them.

The Working Group welcomes comments via the GitHub repository issues by 12 December 2021.
