Monaco CSS

CSS language plugin for the Monaco Editor. It provides the following features when editing CSS, LESS and SCSS files:

• Code completion
• Hovers
• Validation: Syntax errors and linting
• Find definition, references & highlights for symbols in the same file
• Document Symbols

Linting an be configured through the API. See here for the API that the CSS plugin offers to configure the CSS/LESS/SCSS language support.

Internally the CSS plugin uses the vscode-css-languageservice node module, providing the implementation of the functionally listed above. The same module is also used in Visual Studio Code to power the CSS, LESS and SCSS editing experience.
