Being able to control the `paint-order` in CSS means you can push the stroke behind the fill, fixing awkward issues with ruining letterform readability.

There is an already-classic @scope demo about theme colors. Let’s recap that and then I’ll show how it relates to any situation with modifier classes. (The @scope rule is a newish feature in CSS that is everywhere-but-Firefox, but is in Interop 2025, so shouldn’t be too long to be decently usable.) There are lots of […]

You can pluck off values from HTML attributes that actually have types now, so if you put data-font-size=”2.2rem” on an element you could actually, ya know, honor that.

::selection is cool, but scoping it to selectors like :nth-child(5n+2) is even more fun, especially on a love filled ay like Valentine’s Day.

The & is a powerful addition to CSS, allowing us to craft selectors without repetition and helping organization and understanding.
