at-rule or selector expected

[RandLynn]

• I have searched through existing issues

• I have read through docs

• I have read FAQ

• I have tried restarting VS Code or running Vetur: Restart VLS
  A little unsure how to research past help requests for my issue, meanwhile can you tell me why the "at-rule or selector expected error message in VS Code HTML file? Is the red squiggly line an error message or just an annoyance. I am a rookie at all of this - and how do I know if you have responded? Thank you in advance. Regards, Rand L Petersen
