We only have the getComputedStyle convention as querySelector doesn't support pseudo-elements at all. Even the section linked above on unsupported pseudo-element selectors being treated as invalid is only used in a context where an invalid selector means a no-op. The context in which [querySelector](https://dom.spec.whatwg.org/#dom-parentnode-queryselector) runs [scope-match a selectors string](https://dom.spec.whatwg.org/#scope-match-a-selectors-string) which uses the [parse a selector](https://drafts.csswg.org/selectors-4/#parse-a-selector) from selectors-4 which states that [an unsupported psuedo-element selector is treated as invalid](https://drafts.csswg.org/selectors-4/#invalid-selector) throws an exception as a result of the invalid selector. It seems odd to me that we wouldn't have consistent pseudo element parsing. -- GitHub Notification of comment by flackr Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4745#issuecomment-597239938 using your GitHub account
