The SVG G container should have the same size as its children. This
fixes a bug when there was an opacity value on the G element, as in
StackingContext it would try and get a bitmap of the element which would
be empty due to it having no size.
Instead of applying relative offsets (like position:relative insets)
during painting and hit testing, we now do a pass at the end of layout
and assign the final resolved offsets to paintables.
This makes painting and hit testing easier since they don't have to
think about relative offsets, and it also fixes a bug where offsets were
not applied to text fragments inside inline-flow elements that were
themselves position:relative.
Changing `calculate_min_content_heigh()` and
`calculate_min_content_heigh()` to accept width as `CSSPixels`, instead
of `AvailableSize` that might be indefinite, makes it more explicit
that width is supposed to be known by the time height is measured.
This change has a bit of collateral damage which is rows height
calculation regression in `table/inline-table-width` that worked before
by accident.
We now apply MathML's default user agent style sheet along with other
default styles. This sheet is not mixed in with the other styles in
CSS/Default.css because it is a namespaced stylesheet and so has to
be its own sheet.
Using avilable space directly while resolving table container width
allows to avoid assigning it to table wrapper box content width which
sometimes involves infinite (saturated) values.
Also this allows to get rid of set_max_content_width() which is a hack
that allows to bypass set_content_width() to assign infinite
(saturated) width to a box.
Closes https://github.com/SerenityOS/serenity/issues/19521
Replicate the more conservative way it's done for other nodes, for
which we verify whether they have a paintable before doing
painting-related operations with it.
Fixes crash on https://www.haiku-os.org/.
Returning greatest_child_width() from automatic_content_width() in BFC
if root box children are inline and there are min/max-width that caused
width to be changed after IFC layout while content_width should be
always set to correct value by layout_inline_children() regardless of
layout mode.
- Out-of-flow items should not affect grid layout
- "The static position of an absolutely-positioned child of a grid
container is determined as if it were the sole grid item in a grid
area whose edges coincide with the content edges of the grid
container."
We were already parsing non-function-syntax :host, so let's also do
the :host(...) variant. Note that we don't have matching for these yet.
This fixes many issues on sites generated by Wix, as they often have
selector lists that include some :host() selector, and we'd reject the
entire rule after failing to parse it.
This stuff is pretty hairy since the specifications don't give any
guidance on which widths to use when calculating the intrinsic height of
flex items in a column layout.
However, our old behavior of "treat anything indefinite as fit-content"
was definitely not good enough, so this patch improves the situation by
considering values like `min-content`, `max-content` and `fit-content`
separately from `auto`, and making the whole flex layout pipeline aware
of them (in the cross axis context).
Use the max-width of percentage cells instead of min-width as the
reference to be used to compute the total table width. The specification
only suggests that the UA should try to satisfy percentage constraints
and this behavior is more consistent with other browsers.
Fixes infinite spinning in the cases when CSSPixels does not have
enough precision to represent increase per track which happens when
very small extra_space got divided by affected tracks number.
Change associativity in computing of replaced element size to improve
precision of division.
Fixes vertically squashed image from Mozilla splash page MDN example.
This patch implements "Overflow Viewport Propagation" from CSS-OVERFLOW.
It fixes an issue where many websites were not scrollable because they
had `overflow: scroll` on the body element and we didn't propagate it.
Pseudo-elements like ::before and ::after were discarded when their
content property was an empty string (ignoring whitespace), because they
are anonymous containers with no lines.
Our previous way around it was to add an empty line box (see b062a0fb7c)
however it didn't actually work for cases described in the previous
commit.
This makes avatars and cover arts square on last.fm and "fixes" the test
css-pseudo-element-should-not-be-affected-by-presentational-hints.html.
Unfortunately, this also regresses on block-and-inline/clearfix.html,
but that hopefully will be handled in subsequent commit.
Properties like min-width, max-width, etc, should be ignored while we're
trying to determine the intrinsic size of a flex container.
This fixes an infinite recursion when using an intrinsic size keyword as
the max-width of a flex column container.
Note that this behavior is marked as AD-HOC in code comments because
specs don't tell us how to achieve intrinsic sizing.
We can now load product pages on the Twinings site, such as
https://twinings.co.uk/products/earl-grey-100-tea-bags :^)
Fixes the issue that before "automatic minimum size" were used to size
flexible tracks even though specification says is should be "minimum
contribution"
Previously, we always rounded border-widths up when converting them to
device pixels. However, the spec asks us to follow a specific algorithm
to "snap" these values, so that the computed value is snapped.
The difference from before, is that widths of between 0 and 1 device
pixels are rounded up to 1, and and values larger than 1 are rounded
down.
If a math function resolves to `<length>` or `<percentage>`, then it
will by definition also resolve to `<length-percentage>`. (Same for any
other basic types.) Since we were checking `<length-percentage>` first
and then bailing if no given properties could accept that, math
functions would always fail to match a property that just accepts a non
`-percentage` type.
This is a universal value like `initial` and `inherit` and works by
reverting the current value to whatever we had at the start of the
current cascade origin.
The implementation is somewhat inefficient as we make a copy of all
current values at the start of each origin. I'm sure we can come up with
a way to make this faster eventually.
