During the implementation of `anchors-valid` and `anchors-visible`, I found the following things may need clarification about validity/visibility of anchors: 1. Is an anchor valid or visible if - it has `display: none`, - it's under `content-visibility: hidden`, or - it's under `content-visibility: auto` and is currently not rendered. Our current plan is to treat them as invalid because the anchor doesn't exist in the layout tree. 2. For validity of anchor references, - should we iterate all CSS properties to find invalid anchor references? For example, is `border-width: anchor(--a top)` an invalid anchor reference or should it be ignored? - should we check the validity of anchor references from unused `@position-try` styles? - should an anchor reference with missing default anchor (e.g. `width: anchor-size(width)` without a default anchor) be treated as invalid or be ignored? - should we check the validity of anchor references from `anchor-size()`? Our current plan is to only check for validity and visibility for anchor references that are actually resolved, but not including those in unused `@position-try`s. -- GitHub Notification of comment by wangxianzhu Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/7758#issuecomment-2025819783 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
