Sam Atkins	1aa5631610	LibWeb/CSS: Parse @page selectors ... Ideally we'd be able to share the code between page selectors and style ones, but given how simple page selectors are, some code duplication is the simpler option.	2025-05-15 09:53:29 +01:00
Sam Atkins	aaf07ae30d	LibWeb: Add basic implementation of @page ... This doesn't support selectors, and the only descriptors for now are for margins.	2025-05-15 09:53:29 +01:00
Sam Atkins	1002464322	Tests: Import WPT CSSOM and parsing tests for @page	2025-05-15 09:53:29 +01:00
Sam Atkins	4edafb35cd	LibWeb/CSS: Use PendingSubstitutionValue for unresolved shorthands ... Previously, we would just assign the UnresolvedStyleValue to each longhand, which was completely wrong but happened to work if it was a ShorthandStyleValue (because that's basically a list of "set property X to Y", and doesn't care which property it's the value of). For example, the included `var-in-margin-shorthand.html` test would: 1. Set `margin-top` to `var(--a) 10px` 2. Resolve it to `margin-top: 5px 10px` 3. Reject that as invalid What now happens is: 1. Set `margin-top` to a PendingSubstitutionValue 2. Resolve `margin` to `5px 10px` 3. Expand that out into its longhands 4. `margin-top` is `5px` 🎉 In order to support this, `for_each_property_expanding_shorthands()` now runs the callback for the shorthand too if it's an unresolved or pending-substitution value. This is so that we can store those in the CascadedProperties until they can be resolved - otherwise, by the time we want to resolve them, we don't have them any more. `cascade_declarations()` has an unfortunate hack: it tracks, for each declaration, which properties have already been given values, so that it can avoid overwriting an actual value with a pending one. This is necessary because of the unfortunate way that CSSStyleProperties holds expanded longhands, and not just the original declarations. The spec disagrees with itself about this, but we do need to do that expansion for `element.style` to work correctly. This HashTable is unfortunate but it does solve the problem until a better solution can be found.	2025-05-14 11:46:47 +01:00
mikiubo	89e0896cd7	LibWeb: Implement XML Char validation for Text node serialization ... With this fix, the second test in domparsing/innerhtml-01.xhtml passes.	2025-05-14 18:18:08 +12:00
Glenn Skrzypczak	5c578b6057	LibWeb/HTML: Implement report_validity ... This implements the previously stubbed out `report_validity` method. The specification is not very clear on how to exactly report the validity. For now, we bring the first visible invalid control into view and focus it. In the future, however, it would make sense to support more complex scenarios and be more aligned with the other implementations.	2025-05-14 09:39:12 +12:00
stelar7	296d9d74d8	LibWeb/IDB: Implement IDBCursorWithValue interface	2025-05-13 10:48:40 -06:00
Psychpsyo	4989c5c793	LibWeb: Add paint containment clipping ... The contain-paint-stacking-context-001a.html test has been removed for now because it has a 1px tall blue line at the top that should not be there. With paint containment, this line is removed only in the actual test case, but not in the reference. This is because of the font that we use in testing and happens in Chromium as well if the test is run with that font.	2025-05-13 15:30:14 +03:00
Psychpsyo	ed7374783d	LibWeb: Enable different overflow along the x and y axis	2025-05-13 15:30:14 +03:00
Psychpsyo	85883ee5ce	LibWeb: Deduplicate clipping code ... This makes it so that PaintableWithLines no longer has its own bespoke clipping logic, using the same code as regular scroll/ overflow clipping.	2025-05-13 15:30:14 +03:00

Jelle Raaijmakers	70b52e0994	LibWeb: Use efficient background repeat path for either direction ... We're able to efficiently draw repeated bitmaps through Skia, but for backgrounds we only did so if the background was `repeat-x` _and_ `repeat-y`, and not if just one was set. This meant that for backgrounds that were only repeating in one direction, we were taking the slow path. Turns out that this slow path also produced graphical artifacts when zooming in and out, so let's not do that :^)	2025-05-09 21:37:48 +02:00
Timothy Flynn	30e8f3f1ad	LibWeb: Update the <details> layout tree when it is opened/closed ... Otherwise, the arrow painted next to the <details> element does not update. Using a screenshot test here because apparently the direction of the arrow has no effect on the layout or paint trees.	2025-05-09 21:37:14 +02:00
Jelle Raaijmakers	123abe0e79	LibWeb: Overlap float space and left margins for all shared ancestors ... We would only correct for the left margin of the containing block of the child box that we are laying out, but we actually need to correct for all left margins up until the containing block that contains both the float and the child box. Fixes #4639.	2025-05-09 14:13:02 +02:00

Jelle Raaijmakers	c56f7d9cde	LibWeb: Invalidate sibling style for :only-child and :*-of-type ... After f7a3f785a8, sibling nodes' styles were no longer invalidated after a node was removed. This reuses the flag for `:first-child` and `:last-child` to indicate that a node's style might be affected by any structural change in its siblings. Fixes #4631. Resolves the `:only-child` ACID3 failure as documented in #1231.	2025-05-07 14:55:12 +03:00

Aliaksandr Kalenik	b3713db4ab	LibJS: Emit ThrowIfTDZ for identifiers used in assignment expressions ... Error about not-initialized `x` variable access should be thrown for: ```js function foo() { x = 69; let x; } foo(); ``` Progress on test262: ``` Diff Tests: test/staging/sm/expressions/optional-chain-tdz.js ❌ -> ✅ test/staging/sm/expressions/short-circuit-compound-assignment-tdz.js ❌ -> ✅ ``` Fixes https://github.com/LadybirdBrowser/ladybird/issues/4587	2025-05-06 12:06:23 +02:00

sideshowbarker	6237824d99	Tests: Add a bunch of input-element tests (tests only, no code) ... Importing these tests now because they are for input-element types that have requirements related to the constraint-validation API — which we’ve been implementing recently. This commit only imports tests, without any changes to our code.	2025-05-06 09:46:49 +01:00
Bastiaan van der Plaat	58b735010b	LibWeb: Add -webkit-box-* legacy CSS property aliases	2025-05-05 23:36:31 +02:00
Jelle Raaijmakers	71665fa504	LibWeb: Scale font size by 1.15 for line-height: normal ... Browsers such as Chrome and Firefox apply an arbitrary scale to the current font size if `normal` is used for `line-height`. Firefox uses 1.2 while Chrome uses 1.15. Let's go with the latter for now, it's relatively easy to change if we ever want to go back on that decision. This also requires updating the expectations for a lot of layout tests. The upside of this is that it's a bit easier to compare our layout results to other browsers', especially Chrome.	2025-05-05 13:15:56 +02:00
Psychpsyo	7c36a82129	LibWeb: Improve parsing for the CSS contain property ... This makes us actually respect the grammar and nets us a couple extra WPT passes in the parsing section.	2025-05-04 22:24:26 +01:00

Tim Ledbetter	23009779e1	LibWeb: Interpolate font-style values correctly ... These are interpolated by computed value, except a value of `normal` is treated as `oblique 0deg`.	2025-05-03 12:05:22 +02:00
Tim Ledbetter	c0f9b11070	LibWeb: Parse oblique font-style with an angle value	2025-05-03 12:05:22 +02:00
Timothy Flynn	ea77092100	LibWeb: Begin implementing SharedWorker ... Shared workers are essentially just workers that may be accessed from scripts within the same origin. There are plenty of FIXMEs here (mostly building on existing worker FIXMEs that are already in place), but this lets us run the shared worker variants of WPT tests.	2025-05-02 17:48:02 -04:00

Tim Ledbetter	542c3cbe51	LibWeb: Implement the transition-behavior CSS property ... This specifies whether transitions should be started for transitions whose animation behavior is discrete.	2025-05-02 11:07:19 +01:00
Jelle Raaijmakers	295b78f7d3	LibWeb: Do not rely on the layout tree for collapsed line breaks ... The editing command that relies the most on this, `insertLinebreak`, did not perform a layout update after inserting a `<br>` which caused this algorithm to always return false. But instead of actually building the layout tree needlessly, we can check the DOM tree instead.	2025-05-01 15:44:26 +03:00
aplefull	71a4e18bf8	LibGfx: Only include frames with fcTL chunks in the animation ... Before this change, IDAT data was mistakenly always included in the animation. Now we only include frames with explicit fcTL chunks. As per the PNG spec (third edition): "The static image may be included as the first frame of the animation by the presence of a single fcTL chunk before IDAT. Otherwise, the static image is not part of the animation." We also fall back to the IDAT data when APNG has acTL but no fcTL chunks. Test image is 062.png from fDAT-inherits-cICP.html from WPT.	2025-05-01 10:30:00 +02:00
