When determining the intrinsic cross size contribution of a flex item
with a preferred aspect ratio, we have to account for any min/max
constraints in the main axis.
SVG and and CSS border rendering now sits on top of SkPath instead of
the old Gfx::DeprecatedPath.
Due to an imperceptible (255, 255, 255) vs (255, 254, 255) color diff
in one ref test, I changed that test to not depend on border rendering
for a positive result, since that was incidental.
The `start` and `end` value set the text alignment based on the computed
value of `direction`. The default value of `text-align` is now `start`
instead of `left`.
In calculating the base size of a flex item, we have a piece of ad-hoc
code that deals with an item that does have an instrinsic aspect ratio,
but not a cross size to resolve that ratio against. In determining the
actual flex item size however, we also take into account the minimum
content width and height, which assumes the box' intrinsic width or
height when available. This would break having an image as a flex item,
which gets stretched to its maximum size within the flex container
instead of the flex item being shrunk to the instrinsic size of the
image.
Fix this by only stretching flex items that do not have an instrinsic
width nor height set.
Adds additional padding to the end-side of the scrollable overflow
rectangle as necessary to enable a scroll position that satisfies
the requirements of `place-content: end` alignment.
This code previously only allocated enough space in
m_col_elements_by_index for 1 slot per column, meaning that columns
with a span > 1 would write off the end of it.
We now follow the rules from the spec more closely, along with an
unspecified quirk for when the offsetParent is a non-positioned body
element. (Spec bug linked in a comment.)
This fixes a whole bunch of css-flexbox tests on WPT, which already had
correct layout, but the reported metrics from JS API were wrong.
The :host family of pseudo class selectors select the shadow host
element when matching against a rule from within the element's shadow
tree.
This is a bit convoluted due to the fact that the document-level
StyleComputer keeps track of *all* style rules, and not just the
document-level ones.
In the future, we should refactor style storage so that shadow roots
have their own style scope, and we can simplify a lot of this.
Previously, `SVGSVGBox` would have a natural aspect ratio of 0 if it
had a viewbox with zero width. This led to a division by zero, causing
a crash.

This is the expected behavior per the HTML spec. Fixes an issue where
styling these elements wouldn't have the expected effect unless you also
set the display property.
Areas are disassembled into boundary lines on `build_grid_areas()` step,
so we can always use them to find grid item's position during placement.
This way we support both ways to define area: `grid-template-areas` and
implicitly using `-start` and `-end` boundary line names.
- Change min track sizing function to be "auto" when flex size is
specified.
- Never check if min track sizing funciton is flexible, because only
max is allowed to be flexible.
- Address FIXME in automatic_minimum_size to avoid regressions after
making two fixes mentioned above.
When traversing the layout tree to find an appropriate box child to
derive the baseline from. Only the child's margin and offset was being
applied. Now we sum each offset on the recursive call.
Previously the input element was displayed with value 0, when no value
was set in the HTML. Now it uses `value_sanitization_algorithm()`, which
will calculate the default value.
In `value_sanitization_algorithm()` there was a logical mistake/typo.
The comment from the spec says "unless the maximum is less than the
minimum".
The added layout test would fail without the code changes.
Fixes#520
Previously, setting CSS `line-height: 0` on an `input` element would
result in no text being displayed.
Other browsers handle this by setting the minimum height to the
"normal" value for single line inputs.
Like 1132c858e9, out-of-flow elements such
as float elements would get inserted into block level `::before` and
`::after` pseudo-element nodes when they should instead be inserted as a
sibling to the pseudo element. This change fixes that.
This fixes a few layout issues on the swedish tax agency website
(skatteverket.se). :^)
If a flex item has a preferred aspect ratio and the flex basis is not
definite, we were falling back to using stretch-fit for the main size,
since that appeared to match other browsers.
However, we missed the case where we actually have a definite cross size
through which the preferred aspect ratio can be naturally resolved.
