lvmax, svmax, lvmin and svmin CSS units are not being highlighted

[therealPaulPlay]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: Version: 1.100.2
• OS Version: MacOS 15.4

Steps to Reproduce:

1. Create a .css file
2. Use the lvmax, svmax, lvmin or svmin units.
3. The regular vmax and vmin units are being highlighted properly, while these 4 are not.

...here you can see how it is not recognized as a valid unit and is just shown in white.

Thanks for creating this issue! It looks like you may be using an old version of VS Code, the latest stable release is 1.100.2. Please try upgrading to the latest version and checking whether this issue remains.

Happy Coding!

I tested it in 1.100.2 and the issue is still prominent. I'll update the report to say version 1.100.2 instead of 1.100.0.

should move report to upstream grammar repo https://github.com/microsoft/vscode-css

otherwise you can try out the Tree-sitter css setting
