While https://wpt.fyi/css/css-pseudo/marker-font-variant-numeric-normal.html uses nested ::marker, it's not the main point of the test. In fact I was thinking of editing that test to allow it to pass on implementations that do not support nested ::marker, but never got to do it. So I think you should add tests specifically for this.
Also, I don't recall whether the flag allowed nested pseudo-elements in getComputedStyle, but I tend to think it should. See https://github.com/w3c/csswg-drafts/issues/4456, it may need a quick CSSWG resolution to align with what was resolved for web animations. -- Oriol Brufau El dia dimecres, 6 de novembre del 2024 a les 13:55:58 UTC, sakh...@chromium.org va escriure: > Contact emailssakh...@chromium.org > > ExplainerNested pseudo elements styling allows to style ::before::marker > and ::after::marker pseudo elements and will be essential to style > ::column::scroll-marker pseudo elements for the carousel project ( > https://github.com/flackr/carousel/tree/main/fragmentation). > > Specificationhttps://www.w3.org/TR/css-pseudo-4/#marker-pseudo > > Summary > > Allows to style pseudo elements that are nested inside other pseudo > elements.
