HELP US INVENT CSS GRID LEVEL 3, AKA “MASONRY” LAYOUT

Summary from the TLDR Web Dev newsletter

A potential implementation of CSS Grid Level 3 called the “Masonry layout” allows for much more flexibility in designing web pages. Developers would be able to define grid columns, use subgrid functionalities, and explicitly place grid items. Level 3 is still being developed, so the WebKit team is inviting feedback from the web development community to guide the direction of this CSS specification.
