CountBleck	ec051bdec2	LibWeb: Import css/selectors/user-valid.html from WPT	2025-08-14 11:55:02 +02:00
Sam Atkins	7ec374c74c	Tests: Import tests for CSS typed OM ... This is everything except some failing ref-tests, and `css/css-typed-om/the-stylepropertymap/properties/*` because importing a test for every property feels excessive.	2025-08-13 09:47:50 +01:00
Sam Atkins	503d41d02d	LibWeb/CSS: Implement the :heading/:heading() pseudo-class ... Corresponds to part of 65dc095e44	2025-08-13 09:47:28 +01:00
Callum Law	778da0175e	LibWeb: Clamp and censor top-level calc results ... We now clamp the values returned from calc into the allowed range (where we know it) and censor any `NaN`s to `0` both when we resolve and when we serialize. Gains us 76 WPT passes.	2025-08-11 17:10:04 +01:00
Sam Atkins	3b97bdc7bf	Tests: Import WPT tests for table rows with visibility:collapse ... These mostly fail for now.	2025-08-11 11:07:47 +01:00

Callum Law	c3b1013018	LibWeb: Skip inverted non-canonical values when simplifying product node ... This matches the logic with the non-inverted children. Gains us 2 WPT tests.	2025-08-06 14:53:22 +01:00
Tim Ledbetter	1dd3608960	LibWeb/SVG: Apply SVGFeBlendElement blend mode ... Previously, the blend mode was always assumed to be `normal`.	2025-08-06 15:21:03 +02:00
Callum Law	15cee5cc15	LibWeb: Correctly round non-integer z-indexes ... Previously we would just cast to an int. Gains us 3 WPT tests.	2025-08-05 06:37:40 +01:00
norbiros	190745fd58	LibWeb/CSS: Parse initial value using syntax from @property ... Now we pass all WPT tests in: `css/css-properties-values-api/at-property-cssom`. Note: Failing tests were false positives. Proper handling of inheriting values and detecting computational independence will be done in another PR.	2025-08-04 11:08:46 +01:00
Tim Ledbetter	1d9e4a6f62	LibWeb: Parse anchor() function for inset properties	2025-08-03 22:09:31 +02:00
Tim Ledbetter	e36df5ea0a	LibWeb: Serialize background-size auto correctly ... When `background-size` is `auto` in both axes, the `auto` value is no longer repeated.	2025-08-02 08:51:23 +02:00
Tim Ledbetter	f2682bb544	LibWeb: Use correct animation type for border-spacing ... This follows the `css-tables` specification rather than the older CSS2 specification.	2025-08-01 15:18:17 +02:00
Tim Ledbetter	ca9364983c	LibWeb/CSS: Support interpolating filter and backdrop-filter values	2025-07-30 23:29:07 +02:00
Jelle Raaijmakers	c4f5e7bee3	LibWeb: Implement anchor-size(..) function parsing ... This parses `anchor-size(..)` functions in CSS, but does not yet result in a useful `Size`: we need style & layout interleaving similar to container queries for this, since the resulting value depends on layout results. Not supported yet: `anchor-size()` appearing inside a `calc()` node. Adds 4280 WPT subtest passes in `css/css-anchor-position`.	2025-07-30 18:13:59 +01:00
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	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
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
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
Andrew Kaster	50422eb563	Tests: Add XHTML tests for CDATA, PIs and Comment nodes in the DOM	2025-07-19 14:56:20 +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
Sam Atkins	07b5b7ffb6	Tests: Import CSS clip-path: path(...) tests	2025-07-17 13:59:23 -04:00
Sam Atkins	5d1ba658c9	Tests: Import attr()-related WPT tests	2025-07-16 14:47:45 +01:00
Callum Law	1d3e539c09	LibWeb: Account for logical property groups in set_a_declaration ... When setting a declaration for a property in a logical property group, it should appear after all other declarations which belong to the same property group but have different mapping logic (are/aren't a logical alias). Gains us 1 WPT pass.	2025-07-16 11:16:49 +01:00
Callum Law	927cd969b2	LibWeb: Generically serialize "positional-value-list-shorthand"s ... We were previously handling this ad-hoc via logic in `get_property_internal` but this didn't cover all contexts (for instance `CSSStyleProperties::serialized`. Gains us 9 more WPT tests as we now cover properties which weren't included in the previous ad-hoc approach.	2025-07-15 14:26:02 +01:00
Shannon Booth	9054ff29f0	LibWeb/CSS: Parse the ::slotted pseudo-element	2025-07-15 13:54:17 +01:00
Callum Law	d980321a77	LibWeb: Include own shadow root in for_each_shadow_including_descendant ... Fixes a crash in wpt.live/css/cssom/CSSStyleSheet-constructable.html	2025-07-11 16:21:11 +02:00
Callum Law	1a0d4487a8	LibWeb: Implement matches attribute on CSSSupportsRule and CSSMediaRule ... Gains us 4 WPT tests.	2025-07-11 10:57:19 +02:00
Tim Ledbetter	c4cf1ccede	LibWeb: Don't crash when parsing ASF with non comma-separated arguments	2025-07-09 19:47:12 +01:00
Sam Atkins	59f2c8df7a	Tests: Import some custom-property tests ... To make it easier to track progress and regressions in subsequent changes.	2025-07-09 16:44:20 +01:00
Callum Law	ceb1c37ba3	LibWeb: Import CSS logical border property parsing WPT tests	2025-07-09 10:10:38 +01:00
Jelle Raaijmakers	e1c93c0ee8	LibWeb: Import WPT elementsFromPoint test ... This specific test failed for some of the previous iterations of this changeset, so let's import it and use it as a regression test.	2025-07-05 23:56:42 +01:00
Tim Ledbetter	923deb0c01	LibWeb: Parse border-image shorthand property	2025-07-03 10:19:44 +01:00

Tim Ledbetter	9d1373de86	Tests/LibWeb: Import unicode range parsing test from WPT	2025-07-03 08:22:30 +01:00
Tim Ledbetter	78b6032940	LibWeb: Validate operator count when parsing a calculation ... Previously, we would allow calc values such as `calc(min(1 2))`, which would be simplified to `calc(3)` because we assumed that numbers not separated by an operator represented a sum. We now validate that the number of operators we see is as we would expect before collecting these values into a sum node.	2025-07-02 10:12:58 +01:00
Gingeh	0e3386bb4c	LibWeb: Throw SyntaxError when FontFaceSet contains var	2025-07-01 11:50:05 +01:00
Tim Ledbetter	5b522c096e	LibWeb: Add border-*-radius logical properties	2025-07-01 11:16:37 +02:00
Callum Law	8e9753eadb	LibWeb: Correctly compute consistent type when simplifying hypot ... Previously we would never get a valid `consistent_type` as we were trying to make the node types consistent with the initial empty type which isn't possible. Gains us 7 WPT tests.	2025-06-30 14:53:04 +02:00
Tim Ledbetter	90da2f5418	LibWeb: Add the border-block-* shorthand properties	2025-06-30 14:52:18 +02:00
Tim Ledbetter	bf37f3400e	LibWeb: Don't treat "--" as a valid custom property name ... This is reserved for future use by CSS.	2025-06-25 17:09:29 +01:00
Tim Ledbetter	48f56cad08	LibWeb: Handle non-numeric font-weight values in keyframes ... Previously, using `font-weight` with a keyword or `calc()` value inside a keyframe rule would cause a crash.	2025-06-25 09:01:56 +02:00
