SMRTR summary
Meta's StyleX is an open-source CSS styling system that combines the developer experience of CSS-in-JS with the performance of static CSS by compiling styles at build time into atomic classes. The system reduces CSS bundle sizes by up to 80% through deduplication and has become the standard across Meta products like Facebook, Instagram, and WhatsApp, as well as external companies like Figma and Snowflake.
