Comments in rule sets for variable definitions

[carlcs]

All :root {} rule sets with variable definitions are generally removed from the output. But not so if they contain comments. Aiming for a clean CSS file, I'd like to have an option to have these sets (and the comments) removed, too.

:root {
  /* Font stacks */
  --font-family-sans: "Proxima Nova", sans-serif;
  --font-family-serif: serif;
  --font-family-mono: monospace;

  /* More font variables */
  --font-var: normal;
}
:root {
  --var: normal;
}

:root {
  /* Font stacks */

  /* More font variables */
}

Posted this as segmentio/myth#99 yesterday, but this probably belongs here.

Pretty much any half-decent minfier will strip those rules out.

[carlcs]

Sure, but I actually don't want to minify/compress the file. I was hoping that if rework-vars removes empty rule sets without comments, it could also remove empty rule sets with comments. Not that big of a problem though, @necolas.

[necolas]

That behaviour is the result of reworkcss/css. I think it kind of makes sense not to strip rules with comments in them, because you might want to do something with those comments in a css preprocessor.

Unlikely but yeah, who knows! :) I'd say that these comments almost ever belong to the anyhow stripped out variable definitions.
