Not sure if this is what you mean but built in “masonry” support is now part of the CSS spec (barely any browser support yet though.

I was referring mostly to GSS: https://gss.github.io/
I think it was an interesting idea that unfortunately didn't really work out. This was before both flex and grid layouts were a thing, so anything new in this space was exciting really. It's a much better css layout world today than it was 8-10 years ago, and particularly grid layout is a very welcome change, but I can't help but think some great ideas have been left by the wayside. Maybe for good reasons, but still.
