Earlier quoted context omitted.

Can't you mathematically work out how to change the colors/opacity to rearrange the job?

Having that knowledge sounds just as expensive if the operations aren't commutative.

He said it might melt your processor... but on a macbook m3 in arc runs great, like every one of those was amazing.

I'm totally down for some good old fashioned impractical hacking. But just remember, we already have canvas, which can do all this easier, faster, and better.

But with less comedic value. Doing this with nothing but box-shadow is funny, mostly because it is so impractical.

Come on. It's thanks to articles like these I can finally have LLM write all those bullshit CSS hacks for me, and I even get to keep rejecting its commits until it gets it right! (Though honestly, right now, getting GPT-4o to do responsive layout is an exercise in frustration equivalent to doing it myself.)

But at the end of the day Firefox and Chrome are still rendering 1px box-shadow differently at 150% browser zoom. Best hopes for Baseline 2025.
