According to CSS2, the bottom margin of a block container can collapse with the bottom margin of its last in-flow child if `height` computes to `auto`. However, according to CSS Sizing, that was "legacy spec prose" and should be interpreted as "behaves as `auto`". Therefore, cyclic percentages and intrinsic keywords like `min-content` shouldn't prevent margin collapse, because they behave as `auto`. This change aligns Servo with Gecko and Blink, but diverges from WebKit. https://www.w3.org/TR/CSS22/box.html#collapsing-margins https://www.w3.org/TR/css-sizing/#behave-auto Testing: - `tests/wpt/tests/css/css-sizing/margin-collapse-with-indefinite-block-size-001.html` - `tests/wpt/tests/css/css-sizing/margin-collapse-with-indefinite-block-size-002.html` - `tests/wpt/tests/css/css-sizing/margin-collapse-with-indefinite-block-size-003.html` - `tests/wpt/tests/css/css-sizing/margin-collapse-with-indefinite-block-size-004.html` - `tests/wpt/tests/css/css-sizing/margin-collapse-with-indefinite-block-size-005.html` Signed-off-by: Oriol Brufau <obrufau@igalia.com> |
