*Specification* https://drafts.csswg.org/css-anchor-position-1/#position-visibility *Summary* The `anchors-valid` value was implemented as part of https://crbug.com/329703412 but subsequently reverted, due to spec questions about the exact definition of the value. Since that time, the value has been renamed to `anchor-valid` (see https://chromestatus.com/feature/5136123851571200) and also better defined to be clear that only the default anchor matters, resolving a lot of ambiguity, and making this value shippable. *Blink component* Blink>CSS <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ECSS%22> *Web Feature ID* anchor-positioning <https://webstatus.dev/features/anchor-positioning> *Motivation* *No information provided* *Initial public proposal* *No information provided* *Search tags* position-visibility <https://chromestatus.com/features#tags:position-visibility>, anchor-valid <https://chromestatus.com/features#tags:anchor-valid>, anchors-valid <https://chromestatus.com/features#tags:anchors-valid> *TAG review* *No information provided* *TAG review status* Not applicable *Goals for experimentation* None *Risks* *Interoperability and Compatibility* This is new support for a value for `position-visibility` so it should not create compat risks.

Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way). *No information provided* *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5136856479039488?gate=5692419038380032 This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
