Tim Ledbetter	62e52163d6	LibWeb: Interpolate text-shadow values as a shadow list ... This is the same behavior as is currently used for `box-shadow`.	2025-07-30 10:51:50 +02:00
Tim Ledbetter	3ae48776fd	LibWeb: Round integral values to the nearest integer when interpolating ... Previously, color components were being incorrectly rounded when interpolating.	2025-07-30 10:51:50 +02:00
Andreas Kling	81d4079c12	LibWeb: Support CSS content property images (and lists, too!) ... This patch expands our generated content support beyond single strings to lists of strings and/or images. Pseudo-elements like ::before and ::after can now use content:url(...) to insert anonymous image boxes into the layout tree. This is heavily used in Google Docs for UI elements.	2025-07-28 22:46:27 +02:00
Timothy Flynn	c8888609f4	LibWeb: Port the FormAssociatedElement value to UTF-16 ... This porting effort makes it pretty clear we will want a UTF-16-aware GenericLexer. But for now, we can actually make ASCII assumptions about what we are parsing, and act accordingly.	2025-07-28 12:25:11 +02:00
Aliaksandr Kalenik	a6857a6ce1	LibWeb: Log more useful information in display list dump	2025-07-27 10:20:18 +02:00
Abhinav	93a0ef949a	LibWeb: Update x25519 raw key import tests	2025-07-26 10:43:16 -06:00
Timothy Flynn	97548f48de	LibWeb: Port rendered text to UTF-16 ... This migrates TextNode::text_for_rendering() to Utf16String and deals with the fallout. As a consequence, this effectively reverts commit 3df83dade8. The layout test expecation file updates are because we now express text lengths and offsets in UTF-16 code units. The selection-over-multiple-code-units expectation file update actually represents a correctness fix. Our result now matches Firefox.	2025-07-25 18:16:22 +02:00
mikiubo	acf1fe7b05	LibWeb: Return base Document for non-HTML parses ... The HTML specification does not explicitly require a specific return type for parseFromString(), but according to Web Platform TestsDOMParser-parseFromString.html, the expected return value for XML MIME types is a Document—not an XMLDocument.	2025-07-25 10:08:29 -06:00
Jelle Raaijmakers	acc7c2f7f3	LibWeb: Do not use namespace in interface names ... Gives us 20 additional WPT subtest passes in `wasm/jsapi`.	2025-07-25 16:50:45 +02:00
Jelle Raaijmakers	76ee1ce04c	LibWeb: Support wasm module instantiation using a global address ... Fixes 1 WPT subtest in `wasm/core/simd`.	2025-07-25 15:35:27 +02:00
Jelle Raaijmakers	58c3a391a3	LibWeb+LibWasm: Reject module instantiation with correct error type ... The spec tells us to reject the promise with a RuntimeError instead of a LinkError whenever the module's start function fails during module instantiation. Fixes 1 WPT subtest in `wasm/core`.	2025-07-25 15:13:28 +02:00
Jelle Raaijmakers	35ca7f82b0	LibWeb: Add BaseAudioContext::createScriptProcessor() ... This is a deprecated node, but it's still widely used on the web.	2025-07-25 11:48:04 +02:00
Luke Wilde	da5fca15ee	LibWeb: Only expose performance.{timing,navigation} on Window ... They are only valid in a Window context, and the spec only exposes them in Window contexts. Fixes workers crashing on: - https://web.whatsapp.com/ - https://pro.kraken.com/app/trade/btc-usd	2025-07-25 11:46:58 +02:00
Tim Ledbetter	89fb783b42	LibWeb: Throw pre insertion validity errors from the correct global	2025-07-25 09:08:14 +02:00
Jelle Raaijmakers	e029e785d2	LibWeb: Convert Editing API internals to UTF-16 ... Both sides of the Editing internals now have to deal with some awkward converting between UTF-8 and UTF-16, but the upside is that it immediately exposed an issue with the `insertText` command: instead of dealing with code units, it was iterating over code points causing the selection to be updated only once instead of twice. This resulted in the final selection potentially ending up in between a surrogate pair. Fixes #5547 (pasting/typing surrogate pairs).	2025-07-24 07:18:25 -04:00
Luke Wilde	a2f3a5a6ce	LibWeb: Send a beforeinput event for pasting ... This allows us to paste text into Discord.	2025-07-23 22:04:45 +02:00
Tim Ledbetter	062862f315	LibWeb/CSS: Add -webkit-filter as a legacy alias	2025-07-23 09:32:39 +02:00
Glenn Skrzypczak	6e6507c8c5	LibWeb/HTML: Sanitize email input with multiple attribute ... This implements the missing part of the value sanitization algorithm for email inputs with the multiple attribute.	2025-07-22 23:02:33 +01:00
Jelle Raaijmakers	526615bc10	LibWeb: Stub Navigator.getGamepads()	2025-07-22 11:55:29 -04:00
Tim Ledbetter	484a09d6a2	LibWeb: Support interpolating rotate values	2025-07-22 11:09:45 +01:00
norbiros	ab574deb93	Tests: Import some css/css-properties-values-api WPT tests ... Casual import of 4 WPT tests related to `CSS.registerProperty`	2025-07-22 10:57:54 +01:00
norbiros	90c0decd95	LibWeb/CSS: Add CSS.registerProperty JS method ... This adds an *almost* complete implementation of `CSS.registerProperty` method enabling further progress on the `@property` feature.	2025-07-22 10:57:54 +01:00
Tim Ledbetter	92f85d180e	LibWeb: Serialize empty ImageBitmap data as null	2025-07-21 19:19:50 -04:00
Tim Ledbetter	854d48f973	LibWeb: Use correct angle type when serializing hue-rotate filter values ... At some point `hue-rotate` was changed to use `AngleOrCalculated` rather than `Angle`, but `Angle` was still being used in a `visit`, which otherwise defaulted to zero. This caused all `hue-rotate` angles to serialize to zero.	2025-07-22 00:53:10 +02:00
Tim Ledbetter	a990de65e4	LibWeb: Implement SVGViewElement ... This identifies a particular region of an SVG image, which can then be linked to by an SVG fragment identifier.	2025-07-22 00:52:24 +02:00
Timothy Flynn	2dfcc4c307	LibRegex: Compare code units (not code points) in non-Unicode char range	2025-07-21 23:44:18 +02:00
Luke Wilde	8210a7b3e3	LibWeb: Resolve FontFaceSet::load promise with all loaded FontFaces ... The resulting array is required on https://www.canva.com/	2025-07-21 16:29:55 +01:00
dmaivel	52a23dc02e	AK+LibWeb/CSS: Add lower-greek counter style	2025-07-21 15:18:17 +01:00
Sam Atkins	11e2dbb555	LibWeb/CSS: Support text-justify: distribute legacy value alias ... ...for `text-justify: inter-character`. We previously had this mapped in Enums.json, but the behaviour is different: `a=b` in Enums.json keeps `a` around but makes it behave the same as `b`. A legacy name alias is instead expected to replace `a` with `b`, so we have to do that separately.	2025-07-21 10:04:42 +01:00
Gingeh	f38e07e0c5	LibWeb: Don't crash when an unknown property begins with a single dash	2025-07-20 08:54:53 +02:00
Tim Ledbetter	48417152df	LibWeb: Don't crash when creating empty bitmap from a HTMLCanvasElement	2025-07-20 16:26:57 +12:00
Tim Ledbetter	7874f325a8	LibWeb: Implement InputEvent.getTargetRanges() ... This returns a list of ranges that would be affected by a change to the DOM if the input event is not cancelled.	2025-07-20 12:34:14 +12:00
Kenneth Myhra	c0976b18e0	LibWeb: Implement {,de}serialization steps for ImageBitmap ... To make {,de}serialization of ImageBitmap work we also had to add support for creating an ImageBitmap from a HTMLCanvasElement in WindowOrWorkerGlobalScopeMixin::create_image_bitmap_impl().	2025-07-20 12:30:43 +12:00
Timothy Flynn	27d139e817	LibWeb: Define Wasm native errors correctly ... 1. Fix typos in some macro invocations of these error types. We now use a single xmacro to instantiate error definitions to prevent such errors in the future. 2. Use the "WebAssembly." prefix as needed. 3. Allocate the error constructors and prototypes with `realm.create` rather than `heap.allocate`. The latter does not invoke `initialize` methods. This exposed the next issue: 4. Use the correct intrinsic prototype in the error constructor. We were using the base native error prototype. We unfortunately cannot invoke OrdinaryCreateFromConstructor from LibJS directly with the correct prototype, so an implementation was added here. 5. Use intrinsic accessors to create the constructors. I don't think this one was actually a fix, but it makes the setup look more like other built-ins.	2025-07-19 16:48:01 -04:00
Timothy Flynn	6b3f796e5b	LibWeb: Propagate errors from module instantiation	2025-07-19 16:48:01 -04:00
Timothy Flynn	a458a7d35b	LibWeb: Do not coerce object IDL types to JS objects ... We should bail with a TypeError if the provided value is not a JS object already.	2025-07-19 16:48:01 -04:00
Timothy Flynn	7b14da14d8	Tests/LibWeb: Import tests for incorrect Wasm instantiations	2025-07-19 16:48:01 -04:00
Andreas Kling	92221f0c57	LibWeb: Apply all animations and transitions before invalidating style ... This fixes an issue where only the last KeyframeEffect applied to an element would actually have an effect on the computed properties. It was particularly noticeable when animating a shorthand property like border-width, since only one of the border edges would have its width actually animate. By deferring the invalidation until all animations have been processed, we also reduce the amount of work that gets done on pages with many animations/transitions per element. Discord is very fond of this for example.	2025-07-19 11:08:46 -04:00
Andrew Kaster	50422eb563	Tests: Add XHTML tests for CDATA, PIs and Comment nodes in the DOM	2025-07-19 14:56:20 +02:00
Aliaksandr Kalenik	714ff4e3f9	LibWeb: Fix previous style calculation for CSS transitions on pseudo ... ...elements. Adds missing pseudo-element type passed into computed properties getter. Previously, due to this bug, we were using the element's computed properties as the previous computed properties for its pseudo-elements. This caused an excessive number of unintended CSS transitions to run. The issue was particularly noticeable in Discord's emoji picker, where each emoji has `::after` pseudo-element. We were incorrectly triggering transitions on all their properties, resulting in significant unnecessary work in style computation and animation event dispatching.	2025-07-18 21:19:37 +02:00
Callum Law	4ee8110449	LibWeb: Handle flood-opacity in line with other opacity properties ... We now do the proper thing in terms of: - Allowing percentages - Returning the computed value in getComputedStyle - Handling values out of the [0,1] range Gains us 13 WPT passes in the imported tests.	2025-07-18 11:04:55 -04:00
Jelle Raaijmakers	8dd259b8d8	LibWeb: Stub CSSCounterStyleRule ... Just the interface. Adds 6 new WPT subtest passes.	2025-07-18 11:51:41 +01:00
norbiros	7ad01d28a8	LibWeb/CSS: Add basic registered properties with initial values ... Add global registry for registered properties and partial support for `@property` rule. Enables registering properties with initial values. Also adds basic retrieval via `var()`. Note: This is not a complete `@property` implementation.	2025-07-18 11:12:39 +01:00
Sam Atkins	0ff61e5e7b	LibWeb/CSS: Implement path() basic shape	2025-07-17 13:59:23 -04:00
Sam Atkins	07b5b7ffb6	Tests: Import CSS clip-path: path(...) tests	2025-07-17 13:59:23 -04:00
Callum Law	3d7c5115d8	LibWeb: Move Transformation::to_matrix to new CSV resolve methods ... This gains us 2 WPT passes as we now correctly disallow relative lengths in more places in the `DOMMatrix` constructor.	2025-07-17 08:31:52 +02:00
Sam Atkins	27a666f3b2	LibWeb/CSS: Implement type(<syntax>) in attr() ... This lets the `attr()` interpret the attribute's contents as an arbitrary type instead of just as a string or number.	2025-07-16 14:47:45 +01:00
Sam Atkins	5d1ba658c9	Tests: Import attr()-related WPT tests	2025-07-16 14:47:45 +01:00
Callum Law	33cf3d7782	LibWeb: Serialize RGB, HWB and HSL colors with unresolved components ... Gains us 44 WPT passes.	2025-07-16 13:05:33 +01:00
Callum Law	a13f6cdf86	LibWeb: Use correct command in reorder_modifiable_descendants ... Gains us 7 WPT passes in the imported test	2025-07-16 12:40:38 +02:00
