- Change min track sizing function to be "auto" when flex size is
specified.
- Never check if min track sizing funciton is flexible, because only
max is allowed to be flexible.
- Address FIXME in automatic_minimum_size to avoid regressions after
making two fixes mentioned above.
When traversing the layout tree to find an appropriate box child to
derive the baseline from. Only the child's margin and offset was being
applied. Now we sum each offset on the recursive call.
This change makes find-in-page ignore content that’s been added to the
document using CSS ::after or ::before pseudo-elements. Ignoring such
pseudo-element content for find-in-page matches the behavior in Chrome
and Safari (though not in Firefox).
Otherwise, without this change, find-in-page doesn’t ignore the
pseudo-element content, and we instead crash in
DOM::Range::common_ancestor_container after hitting an assert, due to
the start container and end container for the matched range not having a
common ancestor.
Fixes https://github.com/LadybirdBrowser/ladybird/issues/514
Like 1132c858e9, out-of-flow elements such
as float elements would get inserted into block level `::before` and
`::after` pseudo-element nodes when they should instead be inserted as a
sibling to the pseudo element. This change fixes that.
This fixes a few layout issues on the swedish tax agency website
(skatteverket.se). :^)
The first step of the find in page algorithm is to walk the layout tree
of each document on the page and construct a list of strings against
which to search for matches.
Previously, this was being done for each new query, even when the
page content hadn't been updated. The output of this process is now
cached in the viewport node of the associated document. This ensures
that this process is no longer repeated unnceessarily.
The ChunkIterator now limits a chunk to using only one font (before, it
was possible to have a chunk with >1 font, when `unicode-range` CSS
property is used).
This change allows us to reduce some complexity in the text shaping and
painting code and makes us compatible with the APIs in Skia and
HarfBuzz.
And let the old shadow_root(), which was only supposed to be used by
bindings, be called shadow_root_for_bindings() instead.
This makes it much easier to read DOM code, and we don't have to worry
about when to use shadow_root_internal() or why.
If a flex item has a preferred aspect ratio and the flex basis is not
definite, we were falling back to using stretch-fit for the main size,
since that appeared to match other browsers.
However, we missed the case where we actually have a definite cross size
through which the preferred aspect ratio can be naturally resolved.
...and shadow tree with TextNode for "value" attribute is created.
This means InlineFormattingContext is used, and button's text now
respects CSS text-decoration properties and unicode-ranges.
The main intention of this change is to have a consistent look and
behavior across all scrollbars, including elements with
`overflow: scroll` and `overflow: auto`, iframes, and a page.
Before:
- Page's scrollbar is painted by Browser (Qt/AppKit) using the
corresponding UI framework style,
- Both WebContent and Browser know the scroll position offset.
- WebContent uses did_request_scroll_to() IPC call to send updates.
- Browser uses set_viewport_rect() to send updates.
After:
- Page's scrollbar is painted on WebContent side using the same style as
currently used for elements with `overflow: scroll` and
`overflow: auto`. A nice side effects: scrollbars are now painted for
iframes, and page's scrollbar respects scrollbar-width CSS property.
- Only WebContent knows scroll position offset.
- did_request_scroll_to() is no longer used.
- set_viewport_rect() is changed to set_viewport_size().
Previously, we assumed that all label control paintables were of type
`LabelablePaintable`. This caused a crash when clicking on a label with
a text input control.
For bitmap fonts, we will often not have an exact match for requested
sizes. Return the closest match instead of a nullptr.
LibWeb is currently the only user of this API. If it needs to be
configurable in the future to only allow exact matches, we can add a
parameter or another method at that time.
Introduces separate layout and paintable type for foreign element.
It is necessary to inherit SVGForeignObjectPaintable from SVGMaskable
in upcoming changes.
These changes are compatible with clang-format 16 and will be mandatory
when we eventually bump clang-format version. So, since there are no
real downsides, let's commit them now.
This line changes padding top to align cell content to baseline:
`cell.padding_top += m_rows[cell.row_index].baseline - cell.baseline`
Which means available for distribution height `height_diff` could have
changed so it needs to be refreshed before assigning the rest of it to
padding bottom:
`cell_state.padding_bottom += height_diff;`
Fixes https://github.com/SerenityOS/serenity/issues/22032
There was no need to set an available height constraint when doing early
height calculation for inline-flex boxes. It created a situation where
the flex containers could wrongly get zero height early, and then
resolve percentages against zero instead of the real intrinsic size.
Fixes#23942
When both insets in a given axis are auto, we should use the static
position for absolutely positioned elements.
By doing this correctly, we exposed a bunch of other small bugs which
had to be fixed to compensate for new test failures. Those fixes are
included here as well:
- Don't apply margins twice.
- Compute the static position containing block chain correctly.
This makes https://brave.com/ look much better. :^)
Doing multiple `for_each_in_subtree()` passes was kind of a hack. We
can resolve everything in a single pass with a little more control over
the layout process. This also fixes a few minor issues like the sizing
of nested `<g>` elements.
More work is needed here though as this is still fairly ad-hoc.
Note: This does regress `css-namespace-tag-name-selector.html`,
previously SVG text within `<a>` elements would appear. However, this
was only because `for_each_in_subtree()` would blindly look through the
InlineNodes from the unimplemented `SVGAElement`s.
A bunch of this is leftover from pre porting over to new AK::String.
For example, for functions which previously took a ByteString const&
now accepting a StringView.
This uses the same trick as done for masks in #23554. Each use of an
SVG `<clipPath>` becomes it's own layout subtree rooted at it's user.
This allows each use have it's own layout (which allows supporting
features such as `clipPathUnits`).
Implements the "top layer" concept from "CSS Positioned Layout Module
Level 4" specification.
- The tree builder is modified to ensure that layout nodes created by
top layer elements are children of the viewport.
- Implements missing steps in `showModal()` to add an element top top
layer.
- Implements missing steps in `close()` to remove an element from top
layer.
Further steps could be:
- Add support for `::backdrop` pseudo-element.
- Implement the "inert" concept from HTML spec to block hit-testing
when element from top layer is displayed.
Although the flex algorithm as specified does say to determine the cross
size of the flex container, this is not how our layout engine works.
The parent formatting context is responsible for sizing its children,
and since that's already happening, we can simply remove the cross
sizing step from FFC.
