Summary: By using CSS prefers-reduced-motion media feature, web developers can provide contents depending on a system setting that users want *motion-less* content. A WebKit blog post [1] might be useful to know this feature in more detail.
Bugs: https://bugzilla.mozilla.org/show_bug.cgi?id=1365045 for Windows https://bugzilla.mozilla.org/show_bug.cgi?id=1475462 for Mac OSX Link to standard: https://drafts.csswg.org/mediaqueries-5/#prefers-reduced-motion Platform coverage: Windows and MacOSX Though I don't have a plan for Android at this moment , I maybe do it soonish. Estimated release: For Windows in Firefox 63, for MacOSX it might be delayed in Firefox 64 Preference behind which this will be implemented: None Is this feature enabled by default in sandboxed iframes? Yes If allowed, does it preserve the current invariants in terms of what sandboxed iframes can do? I believe so DevTools bug: https://bugzilla.mozilla.org/show_bug.cgi?id=1477920 Do other browser engines implement this? WebKit already shipped this feature on the last year. Neither Chrome and Edge hasn't progressed yet. https://bugs.chromium.org/p/chromium/issues/detail?id=722548 https://developer.microsoft.com/en-us/microsoft-edge/platform/issues/17506002/ web-platform-tests: None This feature is tied to a system setting, so, as far as I can tell, we can't write wpt. WebKit has test cases on their tree controlled by something like our SpecialPowers. We will have reftests controlled by a UI pref. Secure contexts: Yes [1] https://webkit.org/blog/7551/responsive-design-for-motion/ _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
