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.
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.
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.
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.
We know what types and identifiers a property can accept, so we can use
that information to only parse things that can be accepted. This solves
some awkward ambiguity problems that we have now or will face in the
future, including:
- Is `0` a number or a length with no unit?
- Is `3.5` a number or a ratio?
- Is `bottom` an identifier, or a custom-ident?
Two CSS Parser methods are introduced here:
`parse_css_value_for_property()` attempts to parse a StyleValue that the
property can accept, skipping any types that it doesn't want.
`parse_css_value_for_properties()` does the same, but takes multiple
PropertyIDs and additionally returns which one the parsed StyleValue is
for. This is intended for parsing shorthands, so you can give it a list
of longhands you haven't yet parsed.
Subsequent commits will actually use these new methods.
We don't yet have generic parsing support for `<filter-value-list>` or
`<paint>`, so listing them here confuses the new StyleValue parsing code
I'm working on. For now, let's skip `<filter-value-list>` since it's
only used in one pkace which manually parses it, and list the parts of
`<paint>` instead which are taken from here:
https://www.w3.org/TR/SVG2/painting.html#SpecifyingPaint
This is a clear sign that they want to use a UnixDateTime instead.
This also adds support for placing durations and date times into SQL
databases via their millisecond offset to UTC.
That's what this class really is; in fact that's what the first line of
the comment says it is.
This commit does not rename the main files, since those will contain
other time-related classes in a little bit.
