The element establishes a scope for the transition, which means that the transition pseudo-elements are affected by ancestor clips and transforms, and multiple transitions on separate elements can run concurrently. *Blink component* Blink>CSS <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3ECSS%22> *Web Feature ID* view-transitions-element-scoped <https://webstatus.dev/features/view-transitions-element-scoped> *Motivation* View transitions are currently a "global" document-level concept, which means components cannot use transitions without sacrificing composability. For more details, see the explainer. *Initial public proposal* https://github.com/w3c/csswg-drafts/issues/9890 *TAG review* https://github.com/w3ctag/design-reviews/issues/1188 *TAG review status* Issues addressed *Risks* *Interoperability and Compatibility* No compatibility risk as this is a new API. Some interoperability risk due to lack of signals from other browsers. See requests for standards positions from WebKit / Firefox below. *Gecko*: No signal (https://github.com/mozilla/standards-positions/ issues/1352) *WebKit*: No signal (https://github.com/WebKit/standards-positions/ issues/611) *Web developers*: Positive (https://github.com/w3c/csswg-drafts/issues/9890# issuecomment-1927179371) Top feature request from surveyed web authors re. "what is missing from View Transitions". *Other signals*: "I'm salivating." - https://bsky.app/profile/ samwho.dev/post/3mf52aozscc24 *Ergonomics* None. *Activation* None. *Security* Scoped view transitions introduces no new security risks. Security considerations applicable to view transitions in general are described at: https://www.w3.org/TR/css-view-transitions/#sec Scoped view transitions are only for same-document (SPA) transitions, and do not affect cross-document (MPA) transitions. *WebView application risks* None. This feature does not deprecate or change behavior of existing APIs. *Debuggability* DevTools supports inspecting the transition pseudo-tree and pausing / scrubbing the transition animations from the Animations tab. These features work in the same way for both document-scoped and element-scoped view transitions. *Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?* Yes Supported on all Blink platforms. *Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?* Yes WPT directory: css/css-view-transitions/scoped Dashboard link: https://wpt.fyi/results/css/css-view-transitions/scoped?label=experimental&; label=master&aligned *DevTrial instructions* https://github.com/WICG/view-transitions/blob/main/scoped- transitions.md#how-to-use *Flag name on about://flags* enable-experimental-web-platform-features *Finch feature name* ScopedViewTransitions *Rollout plan* Will ship enabled for all users *Requires code in //chrome?* False *Tracking bug* https://issues.chromium.org/issues/394052227 *Measurement* Usage is measured by the web feature "ViewTransitionsElementScoped": https://chromestatus.com/metrics/webfeature/timeline/popularity/281 *Estimated milestones* Shipping on desktop147DevTrial on desktop140Shipping on Android147DevTrial on Android140Shipping on WebView147 *Anticipated spec changes* There is an issue open for the CSS WG to resolve on the name of the containment API, which is currently "view-transition-scope: auto": https://github.com/w3c/csswg-drafts/issues/13123 Hmm, how long would it take to paint this particular bikeshed? Is there a risk of bake-in name-wise? *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5109852273377280?gate=6229325701185536 *Links to previous Intent discussions* Intent to Prototype: https://groups.google.com/a/chromium.org/d/ msgid/blink-dev/67abaada.2b0a0220.1b0c0.01f4.GAE%40google.com Ready for Trial: https://groups.google.com/a/chromium.org/g/blink- dev/c/kafnCyjDMrw/m/4XkuFmk7BgAJ 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.
