The Wix dev team throws their hat into the CSS preprocessor ring:
Stylable is a CSS preprocessor that enables you to write reusable, highly-performant, styled components. Each component exposes a style API that maps its internal parts so you can reuse components across teams without sacrificing stylability.
- Scopes styles to components so they don’t “leak” and clash with other styles.
- Enables custom pseudo-classes and pseudo-elements that abstract the internal structure of a component. These can then be styled externally.
- Uses themes so you can apply different look and feel across your web application.
At build time, the preprocessor converts the Stylable CSS into flat, static, valid, vanilla CSS that works cross-browser.
Looks like Sass luminary Chris Eppstein is getting in on the game of scoped styles with the not-yet-released CSS Blocks. And think of Vue's support for
<style scoped>, and the popularity of utility libraries. I think scoped styles might be the hottest CSS topic in 2018.
