Ali Mohammad Pur	1bcbd008d6	Tests/LibWeb: Rebaseline some no-longer-failing wasm tests	2025-05-08 03:35:11 -06:00
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
stelar7	64c4bea189	LibWeb/IDB: Implement IDBCursor::continue	2025-05-06 11:16:01 +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
Psychpsyo	d048ee3155	Meta: Add doctypes to all svg layout tests	2025-05-04 11:23:52 +02:00

Sam Atkins	09b508d8e8	Tests: Import some URL-related WPT tests	2025-05-03 23:22:40 +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
Bastiaan van der Plaat	832bb978f5	LibWeb: Reject CSS values with unprocessed tokens / extra semicolons	2025-05-02 11:10:02 +01:00
Bastiaan van der Plaat	b99f4872d1	LibWeb: Allow transform calculated length properties	2025-05-02 11:10:02 +01:00
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
Psychpsyo	82387e2127	LibWeb: Avoid changing button border color on disable/hover	2025-04-30 20:13:14 +01:00

Sam Atkins	107d0cafcf	Tests: Disable flaky APNG test ... This frequently flakes on CI.	2025-04-30 11:34:19 +01:00
stelar7	dde80a434c	LibWeb/IDB: Disable test that now hits a timeout	2025-04-29 17:06:17 +02:00
Jelle Raaijmakers	6176b05ca5	LibWeb: Align editing whitespace canonicalization with other browsers ... The spec calls for a couple of very specific whitespace padding techniques whenever we canonicalize whitespace during the execution of editing commands, but it seems that other browsers have a simpler strategy - let's adopt theirs!	2025-04-29 15:30:34 +02:00
Jelle Raaijmakers	35efd4d14b	LibWeb+LibGfx: Support alpha in CanvasRenderingContext2D ... This is implemented by these related changes: * The Skia alpha type 'Opaque' is selected for surfaces that were created with the intention of not having an alpha channel. Previously we were simply creating one with alpha. * Clearing now happens through Skia's `clear()` which always uses the source color's value for the result, instead of setting all values to 0. * CanvasRenderingContext2D selects a different clearing color based on the `alpha` context attribute's value.	2025-04-29 13:51:23 +02:00

Hikmat Jafarli	bd9d489370	LibWeb: Re-evaluate the style block when the type attribute changes	2025-04-29 01:01:02 +02:00
Tim Ledbetter	e7ae9c8ebf	LibWeb: Parse all as keyword in transition shorthand ... This ensures that the parsing of the `transition` shorthand property behaves in the same way as the `transition-property` longhand.4	2025-04-28 20:51:36 +02:00
Tim Ledbetter	04fde1c550	LibWeb: Ensure lang pseudoclass matches multiple segment subcodes	2025-04-28 11:29:30 +01:00
Tim Ledbetter	74c803c87b	LibWeb: Ensure |= value selector handles multiple segments correctly ... Previously, the `|=` would not compare strings containing `-` characters correctly because it would only compare the element attribute up to the first `-` character.	2025-04-28 11:29:30 +01:00
Tim Ledbetter	f854f644a7	LibWeb: Don't crash when interpolating non <number> scale values	2025-04-28 11:46:34 +02:00
Tim Ledbetter	8a398e7a88	LibWeb: Parse all transition-property value as keyword ... We were previously parsing this value, as a custom-ident, meaning that the code path for handling the `all` case wasn't being followed.	2025-04-27 09:49:00 +01:00
Timothy Flynn	ac1c2a956a	LibWeb: Implement caching of reflected element array attributes ... For attributes like Element.ariaControlsElements, which are a reflection of FrozenArray<Element>, we must return the same JS::Array object every time the attribute is invoked - until its contents have changed. This patch implements caching of the reflected array in accordance with the spec.	2025-04-26 17:29:38 -04:00
Shannon Booth	31a3bc3681	LibWeb: Implement 'State-preserving atomic move integration' ... This was recently added to both the HTML and DOM specifications, introducing the new moveBefore DOM API, as well as the new internal 'removing steps'. See: * 432e8fb * eaf2ac7	2025-04-26 08:45:37 -06:00
Andreas Kling	d8ea16d94e	LibWeb: Don't assume calc() simplification worked on invalid tree ... Fixes #4469	2025-04-25 16:55:05 +02:00
Andreas Kling	cf704cfbfc	LibWeb: Implement interpolation for CSS scale values ... And let's handle the 3rd (Z) scale parameter as well, while we're here. At least 242 new passes on WPT.	2025-04-25 14:08:12 +02:00
Andreas Kling	4f4b43f1d2	Tests: Import WPT test for CSS scale interpolation	2025-04-25 14:08:12 +02:00
Jelle Raaijmakers	2fc1cafb8a	LibWeb: Exclude fixed positioned boxes from scrollable overflow ... Sometimes fixed positioned boxes would extend the viewport's scrollable overflow, which according to the spec should never happen. There are some nuances to this, such as properly determining the fixed positioning containing block for a fixed position box, but for now this prevents some pages from being overly scrollable. Fixes horizontal scrollability of https://tweakers.net.	2025-04-25 14:07:38 +02:00
Andreas Kling	27efb3b140	LibWeb: When declarative shadow attachment fails, continue in right spot ... If attachment fails for whatever reason (e.g the host element is not allowed to be a host), the HTML spec tells us to insert the template element anyway and proceed. Before this change, we were recomputing the insertion location at this point, which caused it to be *inside* the template element. Inserting the template element into itself didn't work, and so the DOM would end up incorrect. The fix here is to simply use the insertion point we determined earlier in the same function, before putting a template element on the stack of open elements. We already do this elsewhere. Fixes at least 228 subtests on WPT. :^)	2025-04-25 11:01:17 +02:00
Andreas Kling	43eea9212d	Tests: Import comprehensive WPT test for declarative shadow attachment	2025-04-25 11:01:17 +02:00
Andreas Kling	10cff06a95	LibWeb: Move presentation attrs from SVGGraphicsElement to SVGElement ... This matches how other browser behave and fixes a bunch of WPT tests.	2025-04-25 10:18:34 +02:00
