Our Commentary ​

CSS @function is one of those features that feels like it should have been there forever. It's a game-changer for creating truly dynamic and reusable styles. I'm glad to see articles diving into the "gotchas" and DX, because that's where the real learning happens. It's not just about what you can do, but how smoothly you can do it.
