Sure would be nice to be able to use this in production apps as it makes things load really nicely in Chrome and Edge but I have to opt for less attractive and old techniques because of Safari. 2119159 5 bannostookaylo 2025-05-22 18:15:48 -0700 Is there any kind of eta of releasing import with type CSS? Being able to import CSS would be a game changer. I know because I wrote my app with it but only tested with chrome like a noob. I had to revert everything to accommodate FF and Safari. 2137084 6 bannostookaylo 2025-08-17 16:08:22 -0700 How's this going? Having the ability to confidently import CSS across browsers will be huge for browser development. 2137633 7 jochen.kuehner 2025-08-19 23:36:32 -0700 FF will ship it in one of the next Versions: https://bugzilla.mozilla.org/show_bug.cgi?id=1720570#c10 2144055 8 casey 2025-09-18 11:38:45 -0700 It would be great to have some sort of signal on intent/desire to ship this capability, even if timing/priority is not known at this time — thanks for considering 2152322 9 ncpncebij 2025-10-18 02:18:12 -0700 Any updates on this feature? It’s pretty crucial for the future of framework-free web apps. 2169943 10 casey 2026-01-06 23:09:29 -0800 Checking in on this thread for any new signs. Best I have found is an older thread which indicates support on 2023-11-14: https://github.com/WebKit/standards-positions/issues/77 Import attributes with {type: 'css'} availability: Chrome 123 (Release date: ⁨2024-03-19⁩) Firefox 147 (Release date: ⁨2026-01-13⁩) https://webstatus.dev/features/css-modules 2208802 11 bannostookaylo 2026-05-07 17:47:38 -0700 This currently works in Chrome, Firefox, Edge, and Opera, but fails in Safari due to what appears to be a WebKit-specific issue with CSS imports. At the moment it’s difficult to justify adding browser-specific workarounds for Safari when the behavior diverges from every other major browser engine. Any clarification on whether this behavior is intentional or planned to be addressed would be appreciated. 2212828 12 casey 2026-05-20 23:00:31 -0700 For reference, here are all Interop request/rejection threads for CSS Module Scripts: 2026: CSS Module Scripts #1056 — https://github.com/web-platform-tests/interop/issues/1056 2025: CSS Module Scripts #703 — https://github.com/web-platform-tests/interop/issues/703 2024: CSS Module Scripts #597 — https://github.com/web-platform-tests/interop/issues/597 2023: CSS Module Scripts #206 — https://github.com/web-platform-tests/interop/issues/206 It would be great to see this issue have an assignee or any disposition indicating an intent to implement Thank you for considering 2242479 13 kiet.ho 2026-08-21 01:26:03 -0700 Pull request: https://github.com/WebKit/WebKit/pull/72110 2242789 14 andseier 2026-08-22 09:15:00 -0700 Amazing to see a PR up for this — thanks so much for prioritizing ❤️ 2254761 15 kiet.ho 2026-09-25 14:39:37 -0700 Pull request: https://github.com/WebKit/WebKit/pull/74961 2255412 16 kiet.ho 2026-09-28 02:53:13 -0700 *** Bug 222750 has been marked as a duplicate of this bug. *** 2259018 17 kiet.ho 2026-10-05 13:09:39 -0700 Submitted web-platform-tests pull request: https://github.com/web-platform-tests/wpt/pull/63294 2259688 18 ews-feeder 2026-10-06 13:39:26 -0700 Committed 322887@main (b1913f6615d4): <https://commits.webkit.org/322887@main> Reviewed commits have been landed.
