We're about to stop letting 0 NumericStyleValues pretend to be Lengths,
so this will break. As noted, the flex-basis property accepts
`<length>` not `<number>` so this is actually correct.
Only NumericStyleValue holds integers.
I'm not sure our current distinction between NumericStyleValue holding
an integer or non-integer is useful given it always returns a float.
:thonk:
In order to support intrinsic size keywords (such as fit-content), we
need to be able to calculate the intrinsic sizes of any element, not
just those that form their own formatting context.
When a non-FC-root element is passed to calculate_some_intrinsic_size(),
we now create a synthetic BFC to handle sizing of them.
...and keep a forwarding header around in VP9, so we don't have to
update all references to the class there.
In time, we probably want to merge LibGfx/ImageDecoders and LibVideo
into LibMedia, but for now I need just this class for the lossy
webp decoder. So move just it over.
No behvior change.
Introduces incomplete parsing of grid shorthand property. Only
<grid-template> part of syntax is supported for now but it is enough
to significantly improve rendering of websites that use this shorthand
to define grid :)
The path for floating, replaced elements must not fall through to the
path taken for floating, non-replaced elements. The former works like
inline replaced elements, while the latter uses a completely different
algorithm which doesn't account for intrinsic ratio. Falling through
overrides the correct value computed by the former.
Fixes#19061.
This fixes the issue when margin collapsing state was always reset if
a box has clear property not equal to none even if it does not actually
introduce clearance.
This was crashing on google.com with the linux chrome user agent,
interestingly it seems like this behavior may have been accidental as
only two of the three `parse_number()` were changed in f7dbcb6
Ignore anonymous block boxes when resolving percentage weights that
would refer to them, per the CSS 2 visual formatting model
specification. This fixes the case when we create an anonymous block
between an image which uses a percentage height relative to a parent
which specifies a definite height.
Fixes#19052.
Implied point = point created by two subsequent "off curve" points.
Fixes following issues in function that builds glyph path from points:
- If first point is "off curve" it was wrongly treated as "on curve"
which caused wrong first point position in the path.
- If both first and last points in the path are "off curve" implied
point was not created between them which caused wrong path shape in
the end of the path.
If CSS requests a font that we have loaded, but we didn't associate it
with a specific weight and/or slope, let's still use it if it matches
the family name.
This is a hack until we implement proper CSS font selection.
The free block list now gets populated on opening a database file.
Ideally we persist this list inside the heap itself, but for now this
prevents excessive heap growth.
Previously, only the first block in a chain of blocks would be
overwritten while all subsequent blocks would be appended to the heap.
Now we make sure to reuse all existing blocks in the chain.
We now create a flex container inside the input element's UA shadow tree
and add the placeholder and non-placeholder text as flex items (wrapped
in elements whose style we can manipulate).
This fixes the visual glitch where the placeholder would appear below
the bounding box of the input element. It also allows us to align the
text vertically inside the input element (like we're supposed to).
In order to achieve this, I had to make two small architectural changes
to layout tree building:
- Elements can now report that they represent a given pseudo element.
This allows us to instantiate the ::placeholder pseudo element as an
actual DOM element inside the input element's UA shadow tree.
- We no longer create a separate layout node for the shadow root itself.
Instead, children of the shadow root are treated as if they were
children of the DOM element itself for the purpose of layout tree
building.
