It's matched in the following ways in Gecko right now (at least in a nightly with various default-disabled stuff enabled; item 2 below is not enabled by default yet and closest() is not supported in a shipped release yet): 1) When matching selectors from a scoped stylesheet, :scope matches the parent of the <style scoped>. 2) When matching selectors for shadow DOM <content>, :scope matches the shadow host. 3) When doing querySelector/querySelectorAll, :scope matches the node the call happened on. 4) When doing closest() or matches(), :scope matches the node the call happened on. 5) In all other cases, when matching an element E, :scope will match E.ownerDocument.documentElement. I guess only cases 1 and 5 are really "CSS" from your point of view, right? Note that we do not implement queryAll yet, so haven't had to really look into what happens there. I can't speak for other UAs. -Boris
