This fixes a bug where, if a non-existent font family is specified in
CSS, whitespaces would be rendered using the emoji font, while letters
would use the default font. This issue occurred because the font was
resolved separately for each code point. Since the emoji font was listed
before the default font, it was chosen for whitespace characters due to
its inclusion of whitespace glyphs (at least in the Apple Color Emoji
font on macOS). This change resolves the issue by placing the default
font before the emoji font in the list.
Tests with different combinations of missing width, height
and viewBox.
All tests confirmed to work on Ladybird:
- exactly the same as Chromium (131.0.6778.85)
- almost the same as Firefox (129.0.2)
- only difference: standalone-w.svg: same size, different alignment
This means that an `<input type=password>` will show the correct number
of *s in it when non-ASCII characters are entered.
We also don't need to perform text-transform on these as that doesn't
affect the output length, so I've moved it earlier.
compute_inset() was incorrectly retrieving the containing block size
because containing_block() is unaware of grid areas that form a
containing block for grid items but do not exist in the layout tree.
With this change, we explicitly pass the containing block into
compute_inset(), allowing it to correctly provide the containing block
sizes for grid items.
Letter spacing is applied during text shaping and `shape_text` is used
in places other `InlineLevelIterator` so way may have more work to do,
however this is a good start :^).
Use the `writing-mode` property to determine what values should be used
for computing each element's rect on the screen. If it is a vertical
mode, swap the inline and block, lengths and offsets.
This only lays out whole inline formatting contexts vertically, and does
not currently support mixing the two orientations in a single context.
When aspect-ratio is degenerate (e.g. 0/1 or 1/0) we should
fallback to the same behaviour as `aspect-ratio: auto` according to spec
This commit explicitly handles this case and fixes five WPT test in
css/css-sizing/aspect-ratio (zero-or-infinity-[006-010])
This condition was included to implement flex containers with auto
height, but it actually can reset the definitive height to 0 for inline
blocks with only replaced elements such as an SVG. Removing the
condition does not break any in-tree test, so let's improve the
situation on the SVG side of things for now.

Per css-ui-4, setting `appearance: none` is supposed to suppress the
creation of a native-looking widget for stuff like checkboxes, radio
buttons, etc.
This patch implements this behavior by simply falling back to creating
a layout node based on the CSS `display` property in such cases.
This fixes an issue on the hey.com imbox page where we were rendering
checkboxes on top of sender profile photos.
On any `display: list-item` Node a CSS pseudo element (`::marker`) needs
to be created. This commit allows the ::maker pseudo element to be
nested within other pseudo elements (e. g. ::before or ::after).
This fixes this WPT test:

- Add support for placement of abspos items into track formed by last
line and padding edge of grid container
- Correctly handle auto-positioned abspos items by placing them between
padding edges of grid container

The video was accidentally removed in commit d5ba665f89.
This adds the video back to the LibWeb/Text/data folder, and validates
that the video loads in the test that depends on it loading.
Before this change, we transferred the input element's line-height to
both the editable text *and* the placeholder. This caused some strange
doubling of the effective line-height when the editable text was empty,
pushing down the placeholder.
When the flex container is sized under a min-content constraint in the
main axis, any flex items with a percentage main size should collapse
to zero width, not take up their own intrinsic min-content size.
This is not in the spec, but matches how other browsers behave.
Fixes an issue where the cartoons on https://basecamp.com/ were way
too large. :^)
We were already allowing intrinsic height layout to see definite widths,
and I can't think of a reason *not* to allow it the other way around.
More importantly, this fixes an issue where things with an aspect ratio
didn't have a height to resolve against before.
Makes the logo show up on https://basecamp.com/ :^)
This is what the spec tells us to do:
The root element’s display type is always blockified,
and its principal box always establishes an independent
formatting context.
Additionally, a display of contents computes to block
on the root element.
Spec link: https://drafts.csswg.org/css-display/#rootFixes#1562
It's possible to resolve box's height without doing inner layout, when
computed value is not auto. Doing that fixes height resolution, when box
with percentage height has containing block with percentage height.
Before:
- resolve used width
- layout box's content
- resolve height
After:
- resolve used width
- resolve height if treated as not auto
- layout box's content
- resolve height if treated as auto
..and delay static position calculation in IFC until trailing
whitespace are removed, because otherwise it's not possible to correctly
calculate x offset.
Containing block for abspos grid items depends on their grid placement:
- if element has definite grid position, then corresponding grid area
should be used as a containing block
- if element does not have definite grid position, then padding edge of
grid container should be used as a containing block
So offset should be adjusted for paddings only for boxes without
definite grid position.
Our current text iterator is not aware of multi-code point graphemes.
Instead of simply incrementing an iterator one code point at a time, use
our Unicode grapheme segmenter to break text into fragments.
When a block container has `clear` set and some clearance is applied,
that clearance prevents margins from adjoining and therefore resets
the margin state. But when a floating box has `clear` set, that
clearance only goes between floating boxes so should not reset margin
state. BlockFormattingContexts already do that correctly, and this PR
changes InlineFormattingContext to do the same.
Fixes#1462; adds reduced input from that issue as test.
