Add the CanvasTextDrawingStyles mixin with the textAlign and
textBaseline attributes. Update fill_text in CanvasRenderingContext2D
to move the text rect by the text align and text baseline attributes.
Wrote a simple HTML example to showcase the new features.
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.
Reactive images that had an image source selected based on viewport
size would only update when the images were first fetched, meaning the
last valid image source would become stuck in an image element. By
implementing the last step for reacting to environment changes, we can
run the proper updates even when the image does not need to be fetched.
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.
The implementation of this plugin is meant to eventually replace all
current audio plugins in Ladybird. The benefits over the current Qt-
based audio playback plugin in Ladybird are:
- Low latency: With direct access to PulseAudio, we can ask for a
specific latency to output to allow minimal delay when pausing or
seeking a stream.
- Accurate timestamps: The Qt audio playback API does not expose audio
time properly. When we have access directly to PulseAudio APIs, we can
enable their timing interpolation to get an accurate monotonically-
increasing timestamp of the playing audio.
- Resiliency: With more control over how the underlying audio API is
called, we have the power to fix most bugs we might encounter. The
PulseAudio wrappers already avoid some bugs that occur with QAudioSink
when running through WSLg.
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.
- Requesting an unsupported image type will now fallback to PNG
(which is now always the case),
- Errors should return 'data:,' instead of empty string,
- Added spec comments
Instead, perform the filtering for each rule as we go. This avoids
creating a separate list of rules, which was ~5% of runtime when
mousing around on the Discord web interface.
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.
...along with `outline-color`, `outline-style`, and `outline-width`.
This re-uses the existing border-painting code, which seems to work well
enough!
This replaces the previous code for drawing focus-outlines, with generic
outline painting for any elements that want it. Focus outlines are now
instead supported by this code in Default.css:
```css
:focus-visible {
outline: auto;
}
```
Don't give up if we can't parse that single value for the property
directly, but let the parsing code carry on and see if we can produce a
CompositeStyleValue.
I'm not sure if this is exactly correct, the link to CSS2 spec above
says something that clearance cannot separate boxes, but I'm not sure if
I understood it correctly or if I've done it in the right place.
However, this change fixes our block-and-inline/clearfix.html test again
(was regressed in previous commit).
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.
This reverts commit b062a0fb7c.
This made a calculation of pseudo-elements' height incorrect when they
had `height` set to `auto` and used other techniques (like setting
`padding-top`) to set height, as it was now also adding an empty line.
Additionally, the case didn't work for content containing whitespace
characters, so a pseudo-element with `content: " "` didn't have *this*
particular problem.
This patch adds handling of the 'object-fit' CSS property to the
painting of HTML Image Elements.
This is achieved by first calculating the rect which the image would
need if it were to fully expand into open space and then adequately
cropping it to fit into the image's box.
scale-down is not supported for now.
This fixes the "last changed" time for files on GitHub. Note that this
appears to be in accordance with the shadow DOM specification, but I
can't find a line that neatly says it. Though on Google's post about
shadow DOM v1 it says:
> "the element's shadow DOM is rendered in place of its children."
