Do you need it? Not really, custom properties are probably a better bet. But it still has a bit of utility and it’s fun to think about.

Now that we’re starting to be able to apply types (like `number`) to values of attributes we pull of HTML elements in CSS, doing interesting things with is easier.

Using hard color stops with `repeating-conic-gradient()` and the double-stop syntax, we can pretty easily create a burst background. Then get fancier.

These buttons animate from a square to an arrow, and we look at three different ways to do it, each with their own upsides.

Shadows don’t have to be used for… shadows. Inset shadows can layer over backgrounds and because they are animatable, it’s just another tool for drawing what we want to the page.

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.
