Hi, In bug 1398482 I'm unprefixing the grid-gap, grid-row-gap, and grid-column-gap properties. The old names becomes aliases for the respective unprefixed property. I'm also adding support for the 'normal' keyword to these properties and making it the initial value, per spec [1].
I'm also adding support for percentages to the existing unprefixed column-gap property (which is only supported in multi-column layout until now) in bug 1398537. It already supports 'normal', so with these changes it has the same syntax as the updated grid-column-gap property so we can now "merge" them. These properties also applies to Flexbox: https://drafts.csswg.org/css-align-3/#gap-flex We haven't implemented layout for that yet[2], so one could argue that we shouldn't unprefix the grid-* properties until we do. I think we should anyway, for two reasons: 1. Chrome decided to ship them[3] without Flexbox layout support, so it will likely lead to Grid web-compat issues soon unless we do the same 2. column-gap is already in the wild, so the problem already exists for this property with the spec generalizing it to Grid/Flexbox /Mats [1] https://drafts.csswg.org/css-align-3/#column-row-gap [2] https://bugzilla.mozilla.org/show_bug.cgi?id=1398483 [3] https://groups.google.com/a/chromium.org/forum/#!msg/blink-dev/UViBfJuuIq8/w7_2W7lLAgAJ _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
