[css] CSS intellisense for @starting-style #231960

Open iownbey opened 2 weeks ago

iownbey commented 2 weeks ago

Type: Bug

.example {
    @starting-style {
        opacity: 0;
    }
}

This css should not throw a syntax error, but @starting-style is not recognized, giving me the error Unknown at rule @starting-stylecss(unknownAtRules)

Let me know if you need any more info

For the record, this is something I would be willing to try making a PR for

@iownbey That would be great. The changes need to be made in https://github.com/microsoft/vscode-css-languageservice.

https://github.com/microsoft/vscode-css-languageservice/blob/main/src/parser/cssParser.ts

Let me know if you need help. Add a new tests to develop this: https://github.com/microsoft/vscode-css-languageservice/blob/2326c0cb8c245a148d0f5c0ac0f2c335c6c2fb10/src/test/css/parser.test.ts

Once fixed there I'll bring the node module to VS Code.
