It's great to see Firefox shipping CSS anchors, but I hope they can reduce some compatibility issues before shipping.
Is position-try-fallbacks included in this release? https://bugzilla.mozilla.org/show_bug.cgi?id=1987954 It appears many features remain unimplemented in Firefox; it would be helpful to have a list detailing them. Chrome 144 introduced a series of updates to anchor behavior; Firefox should also have a roadmap. https://chromium-review.googlesource.com/c/chromium/src/+/7076551 Additionally, I believe ship should provide full support for pseudo-elements beforehand, as this is a common use case for CSS anchors. - https://bugzilla.mozilla.org/show_bug.cgi?id=1993698#c2 - https://bugzilla.mozilla.org/show_bug.cgi?id=1993699 - Compatibility issues with the `position-anchor` and `anchor-center` keywords. ```html data:text/html;charset=UTF-8,<!DOCTYPE html> <style> .anchor { anchor-name: --a; background: pink; width: 50px; height: 50px; } .tooltip { font-family: arial, sans-serif; background: green; border: 2px solid red; margin: 0; position: fixed; position-area: bottom; position-anchor: --a; justify-self: anchor-center; } </style> <div class="anchor"></div> <div class="tooltip"> tooltips tooltips </div> ``` 在2025年12月3日星期三 UTC+8 05:45:31<Jonathan Watt> 写道： > As of today (2025-12-02) I intend to turn CSS Anchor Positioning on by > default. > It has been developed behind the layout.css.anchor-positioning.enabled > preference.
