A language service for CSS.
(Work In Progress) It provides full-featured language support, including code completion, diagnostics, hover, and more. Compliant with the Language Server Protocol, CSSlsrs can be integrated into language servers written in Rust or via WebAssembly. We use Biome's CSS parser behind the scenes.
