Tagging for discussion at the upcoming F2F. I've published an explainer detailing Tab's proposal at the top of this issue and answering the open questions: https://github.com/MicrosoftEdge/MSEdgeExplainers/blob/main/AtRuleFeatureDetection/explainer.md The biggest open question I saw in the previous discussion of this issue was what to do with unrecognized media features, since they are accepted by the MQ grammar but can't return a meaningful answer. The explainer proposes that they should return false from a feature query. I use the term "forgiving catch-all grammar" in the explainer, which we can bikeshed. In the context of MQs it means `<general-enclosed>`, but perhaps there's different cases in other grammars that we'd want to treat similarly. The explainer also proposes answers to the linked sub-issues: - `@import` is testable but `@charset` is not since the latter is not an at-rule. - Nested at-rules can be tested either standalone by name or in context. - Any declaration, either a descriptor or a property, can be tested in the third form. -- GitHub Notification of comment by kbabbitt Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/6966#issuecomment-3151467036 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
