Last we checked in with how the web platform was planning on helping us with “masonry” layout, it was a versus battle between “just use grid” and “make a new layout type”. Now Apple folks have an idea: a new shorthand property called item-flow. Nothing is decided here (I don’t think), but it seems very sensible. I like how it has meaning to multiple layout modes, potentially opening up new possibilities instead of masonry alone. They are going to elaborate in a future post, but it sounds like item-pack: collapse; is the road to masonry specifically, perhaps across multiple layout modes.
I’ll repoint to my feeling that reading-order is very related and also opens possibility in that we can use what we’ve already got in broader ways without negative accessibility implications.
