Shouldn't a CSS engine just ignore directives it doesn't know? At least it shouldn't fail without an error.

  Came here to say exactly that: CSS was designed to be friendly and just ignore any line it doesn’t understand. It’s the whole point of browsers and progressive improvements.

  Yes, every single CSS standard ever has required that.
