      I don't see any shaming in that post, but I'd like to see clip-path moved to the compositor to make this easier https://bugs.chromium.org/p/chromium/issues/detail?id=686074 …

      If a browser can get layout working at 60fps on a cheap phone, that'd be great! Haven't seen it yet though.

      Width and height for absolute position is trivial to hit 60 with. Only problem is main thread jank. That’s why layout should move off it.

      That's making a lot of assumptions about the content of the el. Also, by requiring abs position you're forcing tricks onto the dev again

      Besides, the interior layout doesn’t change, so it won’t be recomputed. Layout work is trivial.

      Yeah, if you restrict yourself to the simple design in the post, but in reality developers use more complex designs

      If the problem is “don’t lay out the interior during an animation”, then devs should directly request that. Not drop into linear algebra.

      For example, it should be sufficient to set a fixed width for the content to prevent relayout of the inside during animation.

      That's replacing one trick with another. Clip-path is the sensible choice if you want to change the rendered portion without changing layout

      I think if you were to ask average Web developers (not perf geeks) how to write such a thing, they’d reach for width before clip path.

      It’s certainly what I’d do: inner div with fixed width, then animate an outer div’s width/height with overflow:hidden set.

          The use of the fixed inner div is kinda perf-geeky

          Well, it’s needed for the animation to look right. Otherwise with certain layouts you’d see the contents jump around.
