Thomas Gazagnaire has developed Cascade, a comprehensive CSS engine written in OCaml that parses, generates, optimizes, and diffs CSS. The 30,000-line library supports modern CSS features including @layer, container queries, nesting, and new color spaces. It includes cssdiff, a structural comparison tool that can run in browsers via JavaScript compilation.
Background
CSS tooling has traditionally been JavaScript-focused, creating challenges for developers wanting to work with modern CSS features in other programming ecosystems. OCaml is a functional programming language known for its strong type system and use in compiler development.
