emilio has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-lists] Interaction of ::marker with other pseudo-elements. == A few different questions that occurred to me, that should probably be tested and clarified on the spec, and they interact with each other. ### Do `::before` and `::after` generate markers? In #3766 it was clarified that they increment the list-item counter and are considered list items. But do they generate marker boxes? Browsers generally do (Edge didn't use to though, so we may have some leeway). It's a bit weird that we're generating nested pseudo-elements. ### If they do... Do those markers generated by pseudo-elements match selectors from the page? WebKit and Gecko's implementation do show two red bullets here: ```html <!doctype html> <style> li::after { content: "After"; display: list-item; } ::marker { color: red; } </style> <ul> <li>Bar ``` But then that means that you can address a marker generated by a pseudo-element with selectors. Which is inconsistent in the sense that it doesn't happen for `::before` and `::after`. Which carries me to the next question... ### If they do... Does `display` apply to `::marker`? And thus, can `::marker` boxes be list items? If we allow `content` on marker, they can just be a normal box, affected by `display`, and thus have `display: list-item` on them. If generated markers can be list items, then: * Do they increment the `list-item` counter? * Do they generate other markers? I really hope the answer to these two question is "no", but otherwise, how should this work? ```html <!doctype html> <style> li::after { content: "After"; display: list-item; } ::marker { display: list-item; content: counter(list-item) "."; } </style> <ol> <li>Foo <li>Bar ``` I think `::marker` shouldn't be a list-item, even if it's a box with `display: list-item` like @fantasai clarified in #3766, and that it should not increment the list-item counter nor generate other markers.
