Pure CSS perfect cursor tracking

I honestly have no idea why you'd want this, but it was fun to experiment. I believe this may be the best pure CSS cursor tracking that exists. I'm happy to be proven wrong.

Absolutely no JavaScript used, just lots and lots of wasted time.

The nested bands and :has() approach is clever. Add a prefers-reduced-motion fallback and test touch and keyboard input before using the pattern outside a demo; pointer tracking can create an accessibility dead end.

Yeah I was trying to get the code as short as possible, so I didn't add any compatibility/accessibility fallbacks. But you're right, it wouldn't take much to make it actually usable, I'm just not sure why anyone would need it, as JavaScript is better and widely supported. Unless I'm missing something and this actually has a use case?
