parcel/css

A CSS parser, transformer, and minifier written in Rust. Parsing and minifying large files are completed in milliseconds, often with significantly smaller output than other tools. Many other CSS parsers treat property values as an untyped series of tokens. This means that each transformer that wants to do something with these values must interpret them itself, leading to duplicate work and inconsistencies. @parcel/css parses all values using the grammar from the CSS specification and exposes a specific value type for each property. Built on the cssparser and selectors crates created by Mozilla and used by Firefox and Servo. These provide a solid general-purpose CSS-parsing foundation on top of which @parcel/css implements support for all specific CSS rules and properties. One of the main purposes of @parcel/css is to minify CSS to make it smaller. This includes many optimizations.
