VSCode language support for PostCSS and SugarSS

Syntax highlighting for: .pcss .postcss .sss

if you want this plugin to work for *.css file you need manually change "Language mode" in VSCode to PostCSS or add

"files.associations": {
  "*.css": "postcss"
}

to your settings.json (File -> Preferences -> Settings) if you want to treat all css files as postcss by default

• Extension now using a language-server(based on vscode-css-extension and vscode-css-languageservice) and a language-client for an additional functionality, such as color decorators.
