Developers have been experimenting with HTML-in-Canvas, a hexagonal world map-analytics feature, a web-based OS for e-ink devices, replacing image sources using the content property, and more.
HTML-in-canvas always reads to me like “fun demo, future incident” — once your UI’s been flattened into pixels, you’ve made debugging and accessibility someone’s problem at 3am.
I’m not saying nobody should do it, but I’d want to see how they’re handling focus/keyboard nav and basic inspection when a user says “the button’s gone” and you can’t even tab to it.
