The core implementation is most likely won't be changed in the future, but rather be a solid base for extending the functionality of the interface with additional features.

CSSPseudoElement is returned from Element.pseudo(type), where `type` is currently: ::after, ::before, ::marker. CSSPseudoElement is a proxy object that represents a pseudo-element, so, unlike a pseudo-element, CSSPseudoElement always exists. CSSPseudoElement has the following attributes/methods: - The type attribute is a string representing the type of the pseudo-element. - The element attribute is the ultimate originating element of the pseudo-element. - The parent attribute is the originating element of the pseudo-element (Either Element of CSSPseudoElement for nested pseudo-elements). - The pseudo(type) method to retrieve nested pseudo-elements. *Blink component* Blink>CSS <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ECSS%22> *Risks* /Gecko/: No signal (https://github.com/mozilla/standards-positions/issues/1345) /WebKit/: No signal (https://github.com/WebKit/standards-positions/issues/607) /Web developers/: Positive *Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?* Yes *Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?* Yes http://wpt.fyi/css/css-pseudo/events-on-pseudo-element.tentative.htmlhttp://wpt.fyi/css/css-pseudo/CSSPseudoElement-identity.htmlCan we expand testing a bit here?
