Media features are extracted as descriptors instead of value

Media features are extracted as descriptors. Do you want me to report the issue on w3c/csswg-drafts or do you think it can be fixed here?

I take this opportunity to ask an off topic question. Syntaxes of child at-rules are extracted by @webref/css, but not the top-level at-rules. Are you aware of this? Is it also because of a markup issue? Eg. for @keyframes:

@keyframes = @keyframes <keyframes-name> { <rule-list> }

This is not extracted.

<keyframe-block> = <keyframe-selector># { <declaration-list> }

This is extracted.

FWIW, there is already a filed bug about the misusage of “property” in the CSS page spec which acknowledges this is a mistake in the spec

Yes, because I have to parse rule’s contents to check they only contains valid descriptors: I don’t really care about the descriptors are used in their prelude (ie. next to an at-rule).

Ok, then I’m closing this issue. I do not want to bother w3c/csswg-drafts editors/maintainers by asking for a clarification on the definition of a descriptor. It can be probably defined as data associated to a rule (descriptor) vs. (property) data that is a property of an HTML/SVG element, and it can be used anywhere in that rule (descriptor) vs. (property) in a style rule.

Thank you!
