== [css-2025][css-position-3] Add CSS Position 3 to Rough Interop ==
Splitting the discussion from #9770 for adding [CSS Position 3](https://www.w3.org/TR/css-position-3/) to the Modules with Rough Interoperability section of the CSS Snapshot 2025.

Data to consider:

Current status: WD (last published: 11 March 2025), ED from 10 March 2025
[WPT](https://wpt.fyi/results/css/css-position?label=master&label=stable&aligned&q=none(overlay)): passing tests (excluding `overlay`, not sure how to restrict to specific spec. level): Chrome: 1334, Edge: 1334, Firefox: 1288, Safari: 1264; [interop](https://wpt.fyi/results/css/css-position?label=master&label=stable&aligned&q=none(overlay)%20and%20all(status%3Apass)): 1245 / 1337 (93.1%)
Current Snapshot section: Rough Interoperability
Open issues: [on GitHub](https://github.com/w3c/csswg-drafts/issues?q=is%3Aopen+is%3Aissue+label%3Acss-position-3): 55 (~27 substantial for that spec. level), [in spec.](https://drafts.csswg.org/css-position-3/#issues-index): 3

Summary: Very high interoperability, though many open issues.

Note: Sticky positioning was part of [Interop 2022](https://wpt.fyi/interop-2022).
