Regarding DevTools support: the new value can be found in the CSS values auto-complete in the Rules panel, so that's great. But I just wanted to mention the potential inspector feature that could be built around multicol layouts. We have leading tools when it comes to grid support, and I think a similar tool could be done for multicol. Something that highlights the columns, the gaps between them, and the items (especially useful when items span multiple columns). Positioning items in a multicol layout is not nearly as complex as doing the same in a grid layout, so a tool like this is probably not as important. But still worth considering at some point.
Kudos for shipping this feature btw! Great work.
