Re: [csswg-drafts] [css-contain] Allow container query style features to evaluate in a boolean? (#8127)

  > I'm not able to understand what you're trying to say here.

Oh, sorry. 

`<supports-decl>`, which is defined with `( <declaration> )`, evaluates to true if *the CSS processor accepts that declaration within a style rule* (the borrowed part). I suggested that *`<style-feature>` evaluates to true if the CSS processor accepts that property (`<ident>`) within a style rule*, because I knew that *supported CSS property* excludes custom properties.

In the next part of my comment (which I should have split), I say that I would have no problem if `<supports-decl>` were defined to evaluate to true if the result from parsing `<declaration>` represents a declaration that the CSS processor accepts within a style rule. (I think that is what you want, if I understood correctly.)
