CSS Simple Parser

CSS Simple Parser is a highly optimized, lightweight parser for (S)CSS strings, weighing in at approximately 1.5kb (min + gzip). It is designed for blazing-fast performance, benchmarking around 100x faster than PostCSS for typical use cases. Currently at version 3.0.2, the library is actively maintained but adheres to a 'too simple' philosophy, focusing on core rule block parsing. Key differentiators include its small footprint and speed, achieved by intentionally limiting its scope. It supports nested (S)CSS rules but does not handle top-level directives like `@charset` or `@import`, nor does it permit curly braces (`{`, `}`) or semicolons (`;`) within string literals. The Abstract Syntax Tree (AST) it generates is intentionally crude, requiring further processing for complex operations. Its release cadence is feature-driven, with new versions addressing enhancements or bug fixes within its defined scope.
