GSS is a JavaScript layout engine based on Grid Style Sheets (constraint CSS) using Cassowary constraint solver. It enables declarative relational layouts—expressing 'item A aligned to the right of item B'—and compiles these constraints into standard styles at runtime or build-time. Though experimental and labeled unstable, it showcases advanced layout paradigms beyond traditional CSS.

Features

  • Parses GSS constraint styles into layout rules
  • Uses Cassowary.js solver for relational layouts
  • Supports runtime and preprocessed stylesheet application
  • Allows complex alignments via constraints
  • Cross-browser compatibility via JS implementation
  • MIT‑licensed but marked experimental/unstable
