Interactive rating component

• The star icon in the top corner loses its points when I add a background. Is there another way to resolve this perhaps?

• Are there helpful resources or examples I can look at to add validation feedback to the user when they don't select anything and press the submit button? I was thinking about an inline message just above or below the Submit button that says something like "Please select a rating before submitting." but I am too new to JavaScript to even know what to ask.

I know that I want to validate that it is not null in the forEach method, but I also want to stop the user from submitting, probably with a button:disabled state. If there are any useful resources I can look at, please share!
