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
Shannon Booth	0bdcaf02d3	LibWeb/HTML: Only update the image data on fully loaded document ... Documents created by DOMParser and fragment documents do not have an origin set on the document by the spec. These documents also happen to never become fully active. By properly implementing the steps for the <img> element to only update the image data for documents which are fully active, this fixes a crash for img elements in these types of documents. Unfortunately, this is not a full fix for the microtask queue case. This is because it seems possible for node document for an <img> element to be changed during the microtask queue for that document. It is not clear to me how this can be fixed in a nice way.	2025-06-24 09:56:14 +02:00
Callum Law	b0cdc3f03b	LibWeb: Respect writing-mode and direction when mapping logical aliases	2025-06-23 15:19:07 +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
Tim Ledbetter	9b6da84fff	LibWeb/CSS: Implement the font-kerning property ... This sets whether the kerning information stored on the current font is used.	2025-06-23 13:26:48 +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
Glenn Skrzypczak	6b84cd8d11	LibWeb/HTML: Correctly set base elements frozen base url ... This commit implements the fallback to the documents fallback base url if the href of the first base element is a data or javascript url. Additionally the frozen base url is set, if a base element becomes the first base element with an href content attribute because the previous one got removed.	2025-06-23 18:56:42 +12:00
Aliaksandr Kalenik	4ed9f6fcc0	LibWeb: Collapse auto-fit tracks in middle of tracks definition [GFC] ... `collapse_auto_fit_tracks_if_needed()` had a check that does collapsing only if auto-fit is used like `grid-template-columns: repeat(auto-fit, 1px);`, and it didn't work for valid cases when `repeat(auto-fit)` is placed in the middle of definition like `grid-template-columns: 1px repeat(auto-fit, 1px) 1px;`.	2025-06-23 02:29:45 +02:00
Tim Ledbetter	689dff3ee8	Tests: Synchronize imported tests with the WPT repository	2025-06-22 23:51:34 +02:00
Aliaksandr Kalenik	6ec6e755b2	LibWeb: Merge consecutive grid lines in GridTrackSizeList ... Fixes a bug where consecutively defined grid lines were not merged during serialization.	2025-06-22 21:15:40 +02:00
Aliaksandr Kalenik	e6dabdcebe	LibWeb: Serialize grid line names in GridFormattingContext ... `getComputedStyle()` for grid tracks returns style value produced during layout. This is needed to return resolved track sizes values which are thrown away after layout is done. Now GFC produces more correct style value by not ignoring grid line names.	2025-06-21 22:07:08 +02:00
Aliaksandr Kalenik	af602b2555	LibWeb: Align CSS Grid properties parsing with the specification ... Reimplements `grid`, `grid-template`, `grid-template-rows`, and `grid-template-columns` in a way that uses a separate function for each grammar rule defined in the specification. This change results in many additional passing tests from the already imported WPT suite. Most of the remaining test failures are related to incorrect serialization of grid properties.	2025-06-21 22:07:08 +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	dede92aa78	Tests: Update WPT testharness.js to the most recent version ... This ensures that our test output looks the same as that shown in the WPT runner.	2025-06-21 14:58:02 +02:00

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
Aliaksandr Kalenik	b9b6927b85	LibWeb: Fix swapped strings for auto-fill and auto-fit in GridRepeat ... ...serialization.	2025-06-17 17:43:04 +01:00
Sam Atkins	0e168ce631	Tests: Reimport dom/nodes/moveBefore tests ... Apart from these moving out of `tentative/`, the custom-element-move-reactions.html test was updated to be less flaky: 5e87cd92c0	2025-06-17 13:59:01 +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
Tim Ledbetter	6c6219db05	LibWeb: Use shorthand keywords for contain used value where possible ... The used value of `contain` is now set to `strict` or `content` when the relevant set of containment keywords are specified.	2025-06-17 08:17:33 +01:00
Tim Ledbetter	96d8bed35b	LibWeb/CSS: Serialize contain values in canonical order	2025-06-17 08:17:33 +01:00
Callum Law	12c9da2d3f	LibWeb: Serialize grid/grid-template as "none" when applicable ... This exposes a bunch of false-positives in the grid-{shorthand,template}-invalid.html WPT tests, but gains us some new passes as well.	2025-06-16 12:37:40 +01:00
Callum Law	7d81823eb3	LibWeb: Handle CSS-wide keywords in style_property_for_sided_shorthand ... CSS-wide keywords should not be concatenated in the same way as other values unless they are all the same.	2025-06-16 12:37:40 +01:00
Callum Law	62da650992	LibWeb: Don't serialize longhands if we directly serialized shorthand ... The spec assumes that we only store values against expanded longhands, there are however limited circumstances where we store against shorthands directly in addition to the expanded longhands. For example if the value of the shorthand is unresolved we store an UnresolvedStyleValue against the shorthand directly and a PendingSubstitutionStyleValue against each of the longhands. This commit updates the logic so that in the case we serialize a shorthand directly we should also mark it's longhands as serialized to avoid serializing them separately. This also avoids the scenario where we tried to create and serialize a ShorthandStyleValue with PendingSubstitutionStyleValue longhands, so we can remove the check and related FIXME for that.	2025-06-16 12:37:40 +01:00
Callum Law	f8f4da3b90	LibWeb: Don't serialize shorthand with non-uniform CSS-wide keywords	2025-06-16 12:37:40 +01:00
Prajjwal	e1d2582680	LibWeb: Resolve FIXME in media select resource algorithm ... Fixes at least three WPT test that were previously timing out: - html/semantics/embedded-content/media-elements/error-codes/error.html - html/semantics/embedded-content/media-elements/location-of-the-media-resource/currentSrc.html - html/semantics/embedded-content/the-video-element/video_crash_empty_src.html	2025-06-16 23:28:10 +12:00

Tim Ledbetter	68d3ddb1a7	LibWeb: Parse the transform-origin z-value	2025-06-15 16:01:54 +02:00
Tim Ledbetter	a8d5758777	LibWeb: Only resolve transform-origin keywords for the computed value ... Previously, we were resolving these keywords at parse time, which gave an incorrect serialization of the specified value.	2025-06-15 16:01:54 +02:00
