Does syntax highlighting for Textual CSS files (files with the extension .tcss).
It also does highlighting inside CSS and DEFAULT_CSS class variables in Python files:
This extension uses the grammar tcss.tmGrammar.json that is converted from the YAML grammar in the TCSS TextMate grammar repository.
To convert the YAML grammar into this JSON grammar, use
npx js-yaml ../tcss-textmate-grammar/grammar.yaml > syntaxes/tcss.tmGrammar.jsonSee the change log.
