Multiple-column layout, rows, rules, and floats
Recently implemented in Chrome are two of my top asks for CSS—the concept of rows in multiple-column layout, and gap decorations for rows and columns in grid, flexbox, and multicol. Rows (using column-wrap) provide a way to use multicol on the web without risking scrolling up and down to read if the columns become taller than the viewport. Gap decorations mean that, for multicol, you can now add a rule between these new rows. This post is a collection of the things I think would be interesting to do in future. If you think so too, and particularly if you have a great use case for any of these, let me know in the comments.
