From 8ff295747e7f5e205313e4405d5a63ce23fca993 Mon Sep 17 00:00:00 2001 From: Gaming4JC Date: Sat, 28 Sep 2019 23:36:05 -0400 Subject: Issue #1230 - Part 1: Fix Back-computing percentages for intrinsic sizing in Layout CSS-Grid List of relevant patches applied: 1398537 part 2 - [css-multicol] Implement percentages for 'column-gap' (Gecko part). 1434478 part 1 - [css-grid] Stop back-computing percentage grid gaps when the percentage basis is indefinite. Treat them as zero sized instead. 1434478 part 2 - Stop back-computing percentage padding/margin when the percentage basis is indefinite. Treat them as zero sized instead. 1434478 part 3 - Remove IntrinsicISizeOffsetData::hPctPadding/hPctMargin members since they are now unused. 1434478 part 4 - Factor out constants like NS_UNCONSTRAINEDSIZE so they can be used in headers without needing nsIFrame.h (idempotent patch). 1434478 part 5 - Create nsLayoutUtils::ResolveToLength for resolving CSS (idempotent patch). 1434478 part 6 - Propagate a percentage basis to nsIFrame::IntrinsicISizeOffsets for resolving padding/margin. This is needed only for CSS Grid since in other cases we're only using IntrinsicISizeOffsets in the inline-axis and the percentage basis is always indefinite for *intrinsic sizing*. When calculating the intrinsic size of grid items in the grid container's block axis however, we do have a definite size for the grid area in the inline-axis and it should be used per: https://drafts.csswg.org/css-grid/#algo-overview "2. Next, the track sizing algorithm resolves the sizes of the grid rows, using the grid column sizes calculated in the previous step." (Percentage padding/margin for grid items is always resolved against the grid area's inline-size nowadays.) --- layout/base/moz.build | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'layout/base/moz.build') diff --git a/layout/base/moz.build b/layout/base/moz.build index 4308a6e4d..afc683665 100644 --- a/layout/base/moz.build +++ b/layout/base/moz.build @@ -13,6 +13,9 @@ with Files('Display*'): with Files('FrameLayerBuilder.*'): BUG_COMPONENT = ('Core', 'Layout: View Rendering') +with Files('LayoutConstants.*'): + BUG_COMPONENT = ('Core', 'Layout: View Rendering') + with Files('LayerState.*'): BUG_COMPONENT = ('Core', 'Layout: View Rendering') @@ -63,6 +66,7 @@ EXPORTS += [ 'FrameLayerBuilder.h', 'FrameProperties.h', 'LayerState.h', + 'LayoutConstants.h', 'LayoutLogging.h', 'nsArenaMemoryStats.h', 'nsBidi.h', -- cgit v1.2.3
