Is there an extension or a linter that would show inactive/invalid/disabled CSS properties in VS Code similar to dev tools in browsers (see the picture below)? I couldn’t find anything like that.

VS Code often suggests a lot of properties, many of which to a beginner sound like they fit, but they have no effect sometimes and only way to see that is to check in the dev tools in a browser. That can be frustrating and leads can lead to very long style file with a lot of unecessary properties.
