Stitches
CSS-in-JS with near-zero runtime, SSR, multi-variant support
...Stitches has a dedicated React lib, but @stitches/core works with any framework including Vue, Svelte, and even vanilla HTML. Variants are first-class citizens of Stitches. With multiple variants, compound variants, and default variants, you can design composable component APIs which are typed automatically. Stitches has built-in solutions for tokens and theming, which use CSS variables under the hood. You can define multiple themes, then expose them to any part of your app.
