It seems that this is more useful for emoji fonts, have you researched it? ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform

Re: Intent to ship: CSSOM-View Scroll-Behavior CSS Property and CSSOM-View DOM Extensions for Smooth Scrolling
在 2014年10月28日星期二UTC+8上午4时32分46秒，Kip Gilbert写道： As of October 28, 2014 I intend to turn on by default CSSOM-View Scroll-Behavior CSS Property and CSSOM-View DOM Extensions related to smooth scrolling. They have been developed behind the layout.css.scroll-behavior.enabled and layout.css.scroll-behavior.property-enabled preferences. Firefox is the first UA to ship this feature. Chrome has an implementation, disabled by default. Platform coverage: This will be enabled on all platforms except for Fennec. (Fennec will be enabled once the C++ based APZC implementation ships for Fennec) This feature was previously discussed in this intent to implement thread: https://groups.google.com/d/msg/mozilla.dev.platform/mrsNyaLj3Ig/jooFD8rePzAJ Further discussions occurred on www-style: http://lists.w3.org/Archives/Public/www-style/2014May/0255.html http://lists.w3.org/Archives/Public/www-style/2013May/0361.html http://lists.w3.org/Archives/Public/www-style/2014Oct/0014.html Bugs to turn on by default: Bug 1087562 - Enable CSSOM-View scroll behavior CSS property by default (Except for Fennec) Bug 1087559 - Enable CSSOM-View scroll behavior DOM method extensions by default (Except for Fennec) Since the original intent to implement email, the specification has evolved. The CSSOM-View DOM Extensions have been changed to accept dictionaries for options and the 'instant' value for scroll-behavior has been changed to 'auto'. Bug: 964097 - [meta] Implement CSSOM-View smooth scrolling spec Link to standard: http://dev.w3.org/csswg/cssom-view/#smooth-scrolling:-the-%27scroll-behavior%27-property http://dev.w3.org/csswg/cssom-view/#extensions-to-the-window-interface http://dev.w3.org/csswg/cssom-view/#extensions-to-the-element-interface a href=#/a I hope this also has smooth scrolling effect. ___ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
