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	98e63e3dd5	LibWeb: Parse the border-image-outset 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
Callum Law	536f8c395c	LibWeb: Set numeric type of asin, acos, atan calculation results ... Previously we were omitting the numeric type which meant these functions weren't valid in some cases e.g. within rotate() functions.	2025-06-25 05:19:07 +01:00
Tim Ledbetter	1c2b6ae03e	LibWeb: Don't attempt to set the frozen base url on a null base element	2025-06-25 01:33:45 +12:00
Sam Atkins	8b6c32e3ab	Tests: Import tests for scrollParent() and offsetParent()	2025-06-24 15:26:35 +02:00
Callum Law	6584ae0080	LibWeb: Treat CSS selectors containing undeclared namespaces as invalid ... Selectors containing undeclared namespaces should be considered invalid, not just not matching any elements. Gains us 3 new WPT passes.	2025-06-24 12:51:12 +01:00
Tim Ledbetter	b46378085d	LibWeb: Absolutize keyframe values before interpolating	2025-06-24 12:36:47 +01:00
Callum Law	34a52baeed	LibWeb: Add generic functionality for logical alias computed values	2025-06-23 15:19:07 +01:00
Callum Law	cfc8d3031b	LibWeb: Map logical aliases at cascade time ... Previously we would incorrectly map these in `CSSStyleProperties::convert_declarations_to_specified_order`, aside from being too early (as it meant we didn't maintain them as distinct from their physical counterparts in CSSStyleProperties), this meant that we didn't yet have the required context to map them correctly. We now map them as part of the cascade process. To compute the mapping context we do a cascade without mapping, and extract the relevant properties (writing-direction and direction).	2025-06-23 15:19:07 +01:00
Callum Law	80ea865b19	LibWeb: Use correct error for invalid rule in nested insertRule ... When we try to insert a disallowed (non-nested) statement into a CSSGroupingRule we should throw a `HierarchyRequestError` as it being disallowed is a "constraint specified by CSS". Previously we would rely on `Parser::is_valid_in_the_current_context` and throw a Syntax error. There are more constraints to be implemented.	2025-06-23 12:52:40 +01:00
Tim Ledbetter	689dff3ee8	Tests: Synchronize imported tests with the WPT repository	2025-06-22 23:51:34 +02:00
Aliaksandr Kalenik	7b077595c3	Tests: Reimport css/css-grid/parsing/grid-template-columns-computed.html ... Sync this test with upstream WPT where they added a new subtest in this file.	2025-06-21 22:07:08 +02:00

Tim Ledbetter	269d5bb40e	LibWeb: Resolve percentages for opacity properties at parse time	2025-06-19 10:27:35 +02:00
Tim Ledbetter	e0af205d69	LibWeb/CSS: Implement the empty-cells property ... This property sets whether table borders and backgrounds are painted if a given table cell has no visible content.	2025-06-18 14:55:03 +01:00
Tim Ledbetter	c5a3eaaf45	LibWeb: Allow calc() values in steps() easing functions	2025-06-18 08:57:06 +02:00
Veeti Paananen	21b531598d	LibWeb/CSS: Fix reference bug when canonicalizing linear easing stops ... +2 WPT tests	2025-06-18 08:53:10 +02:00
Tim Ledbetter	701fcb9e87	LibWeb: Allow anonymous layer block rule with no declarations	2025-06-17 08:58:00 +01:00
Tim Ledbetter	30cdacc05a	LibWeb: Add flow relative values for the clear property ... Currently `inline-start` and `inline-end` are always treated as `left` and `right` respectively.	2025-06-17 09:26:26 +02:00
Tim Ledbetter	28b24b72bc	LibWeb: Don't resolve flow-relative values for float too early ... This allows `getComputedStyle()` to return the correct value if `float` is set to `inline-start` or `inline-end`	2025-06-17 09:26:26 +02:00
Callum Law	f8f4da3b90	LibWeb: Don't serialize shorthand with non-uniform CSS-wide keywords	2025-06-16 12:37:40 +01:00
