API Reference

css() → LanguageSupport

Language support for CSS.

cssLanguage: LRLanguage

A language provider based on the Lezer CSS parser, extended with highlighting and indentation information.

cssCompletionSource: CompletionSource

CSS property, variable, and value keyword completion source.

defineCSSCompletionSource(isVariable: fn(node: SyntaxNodeRef) → boolean) → CompletionSource

Create a completion source for a CSS dialect, providing a predicate for determining what kind of syntax node can act as a completable variable. This is used by language modes like Sass and Less to reuse this package's completion logic.
