As of Gecko 52, I intend to let CSS Grid ride the trains on all platforms. https://drafts.csswg.org/css-grid/ This also includes all parts of the CSS Box Alignment spec that are relevant to Grid layout: https://drafts.csswg.org/css-align-3/
It has been developed behind the "layout.css.grid.enabled" preference, and has been enabled by default in Nightly and Aurora for some time now. Other UAs shipping this or intending to ship it are: Chrome - intends to ship: https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/hBx1ffTS9CQ Safari - is implementing it (independently): https://bugs.webkit.org/show_bug.cgi?id=60731 Edge - status unknown to me Note about the 'subgrid' feature: We will *not* support the subgrid feature of CSS Grid in this first release. This feature is marked as "at-risk" in the spec and thus not needed for spec compliance. (Chrome is likewise not going to support subgrid in their first release.) This feature was previously discussed in this "intent to implement" thread: https://groups.google.com/forum/#!msg/mozilla.dev.platform/jSmfRivZOrU/ZMPcwySUEW4J Bug to turn on by default: https://bugzilla.mozilla.org/show_bug.cgi?id=1217086 CSS Grid meta bug: https://bugzilla.mozilla.org/show_bug.cgi?id=css-grid The Devtools team is implementing specific tools for Grid: https://bugzilla.mozilla.org/show_bug.cgi?id=1181227 (some of which will ship in 52 I'm told) /Mats _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
