The CSS attr() function is now fully implemented in Chrome Canary and no longer requires a flag

@robpalmer2 Why have zero browsers implemented decorators?

Anchor positioning is the most revolutionary thing to land in CSS since grid. My only minor quibble

@yisibl @LeaVerou @imCGQAQ I would find this useful. Not working in Safari for me, even in Technology Preview. Only seems to work in Firefox Nightly and Chrome Canary?

@juedsaytv @code

TIL Safari supports WebM and AV1 video, but does not support the AV1 codec when used with a WebM container.

I made a JavaScript-free spoiler revealer (Chrome only for now...)

Deno added WebTransport

A new CSS pseudo-class

@argyleink @colmtuite @ryandotfurrer background-clip: border-area, padding-box; worked for me. Is content-area a thing?

@jonsneyers It would make sense to include AVIF in the animations comparison section of the test page. How is that likely to fare against animated JPEG-XL?

I love the Popover API and am excited about customisable <select>, but because the picker uses the top layer, its behaviour inside a scroll container is somewhat weird imo

Controlling the focus styles applied by JavaScript .focus()
