This extension disables VS Code's IntelliSense for CSS:

[twoco]

When the extension is enabled, it's a pain to write css code. No IntelliSense / no autocomplete / no errors / warnings / etc. Similar as using the Notepad from Windows.

The following is set. But emmet alone is not enough. How to enable IntelliSense?

{
  "emmet.includeLanguages": {
    "postcss": "css"
  }
}

sstools.postcss: v1.0.9
vscode: v1.64.2 (Windows 10)

This has been an issue from 2019

Any plans on supporting this?

Not sure why this is still an issue... but here's a quick and dirty fix that seems to work well for me.

{
    "files.associations": {
        "*.css": "tailwindcss",
        "*.pcss": "scss"
    },
    "scss.lint.unknownAtRules": "ignore",
    "emmet.includeLanguages": {
        "postcss": "css"
    }
}

This basically makes your editor see "pcss" files as "scss" files... and in my experience just works.

However...

You might as well just disable the extension at this point...

I faced the same problem, and replacing postcss-language with this plugin solved it perfectly!
