Parcel CSS is a CSS parser, transformer, and minifier based on the
cssparser crate used in Firefox.
It supports fully parsing all CSS rules, properties, and values into normalized
structures exactly how a browser would. Once parsed, the CSS can be transformed
to add or remove vendor prefixes, or lower syntax for older browsers as appropriate.
The style sheet can also be minified to merge longhand properties into shorthands,
merge adjacent rules, reduce
calc() expressions, and more. Finally, the style sheet
can be printed back to CSS syntax, either minified to remove whitespace and compress
the output as much as possible, or pretty printed.
The StyleSheet struct is the main entrypoint for Parcel CSS, and supports parsing and transforming entire CSS files. You can also parse and manipulate individual CSS rules, properties, or values. The bundler module also can be used to combine a CSS file and all of its dependencies together into a single style sheet. See the individual module documentation for more details and examples.
