Complexity: 2
Setup
You need to enable tree sitter for CSS:
"editor.experimental.preferTreeSitter.css": true
Known differences in syntax highlighting
The big one is deprecated properties and values. The old CSS textmate grammar hardcoded a bunch deprecated tokens, We aren't going to support that with tree-sitter. So, some things that are deprecated and shown in red with textmate will not have that treatment with tree-sitter.
Testing
The goal of testing here is to identify places where we don't get the color right. When filing issues, please include a copy/pastable code snippet and the theme name. Pick 3-5 CSS files (even better if you pick examples of uncommon CSS) and do the following:
- Open the file and see if you think any of syntax highlighting colors look off.
- Open VS Code stable and open the same file there, if you see any differences in syntax highlighting, please file an issue, even if the new highlighting is better.
