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	68035a2b8d	LibWeb/CSS: Add the text-rendering property	2025-06-27 16:51:30 +01:00
Aliaksandr Kalenik	594194eb60	LibWeb: Skip serialization of implicit grid lines created during layout ... StyleValues created for grid-template-rows and grid-template-columns by GFC should not include `-start`/`-end` lines implicitly created by grid areas.	2025-06-25 20:45:48 +02:00
Tim Ledbetter	7a6e4f5ec8	LibWeb: Treat a CSS declaration with a "--" property name as invalid	2025-06-25 17:09:29 +01:00
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	b00e57139f	LibWeb/CSS: Treat block at-rules with no block as invalid	2025-06-25 09:02:45 +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
Aliaksandr Kalenik	8d6f2390f6	LibWeb: Set grid-auto-* to initial values when parsing grid-template ... ...as `grid` property value.	2025-06-24 19:14:08 +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
Callum Law	5fcf3d0b05	LibWeb: Combine shared stylesheet parsing functionality ... No functionality changes	2025-06-24 12:51:12 +01:00
Luiz	da14e072b7	LibWeb: Correctly handle serialization of PseudoElements ... Previusly the implementation only was serializing PseudoElements if they were the last element in the CompoundSelector. This caused bugs on Javascript code that referenced their selectorText, where it would be wrong.	2025-06-24 12:44:44 +01:00
Gingeh	b85a8a23a7	LibWeb: Handle percentage font-size values	2025-06-24 12:42:26 +01:00
Tim Ledbetter	b46378085d	LibWeb: Absolutize keyframe values before interpolating	2025-06-24 12:36:47 +01:00
Gingeh	4292344729	LibWeb: Don't skip last keyframe	2025-06-23 21:01:26 +02:00
Callum Law	89a08cb7cf	LibWeb: Update CSSRule parent style sheet whenever parent rule changes	2025-06-23 15:21:36 +01:00
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
Callum Law	4e87f85458	LibWeb: Convert logical property shorthands to full-fledged shorthands ... No functionality changes. This is just prep work for later commits around moving logical alias mapping to cascade time	2025-06-23 15:19:07 +01:00
Callum Law	12581fa995	LibWeb: Resolve conflicts in compute_keyframe_values correctly ... As conflict resolution depends on whether the property was set directly or via a shorthand, we have to store the non-expanded values in the resolved keyframe properties.	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
Callum Law	ef7ba02842	LibWeb: Throw error in insertRule when rule violates constraints	2025-06-23 12:52:40 +01:00
Callum Law	6144154e4f	LibWeb: Ensure valid placement of @import and @namespace rules ... These rules should appear before all other rules (excluding @layer statements and @charset) with @import appearing first.	2025-06-23 12:52:40 +01:00
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	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
Callum Law	d7036daa89	LibWeb: Disallow trailing tokens in @supports(<declaration>)	2025-06-21 11:49:43 +01:00
Sam Atkins	c1d4323cf7	LibWeb: Support counter-* properties on pseudo-elements ... There are multiple things happening here which are interconnected: - We now use AbstractElement to refer to the source of a counter, which means we also need to pass that around to compute `content`. - Give AbstractElement new helper methods that are needed by CountersSet, so it doesn't have to care whether it's dealing with a true Element or PseudoElement. - The CountersSet algorithms now walk the layout tree instead of DOM tree, so TreeBuilder needs to wait until the layout node exists before it resolves counters for it. - Resolve counters when creating a pseudo-element's layout node. We awkwardly compute the `content` value up to twice: Once to figure out what kind of node we need to make, and then if it's a string, we do so again after counters are resolved so we can get the true value of any `counter()` functions. This will need adjusting in the future but it works for now.	2025-06-19 12:35:31 +01:00
Sam Atkins	498e143687	LibWeb/DOM: Stop including Element.h from AbstractElement.h ... We only need the forward declaration here, and this will let us include AbstractElement from Element.	2025-06-19 12:35:31 +01:00
Sam Atkins	dfce9974b5	LibWeb: Remove GeneratedPseudoElement enum ... This doesn't currently provide any value over just using PseudoElement, and makes it harder to work with PseudoElement in other places.	2025-06-19 12:35:31 +01:00
Sam Atkins	a57595faf5	LibWeb: Make [resolve,inherit]_counters() take AbstractElement ... This is one of those cases where the spec says "element" and means "element or pseudo-element". The easiest way to handle both is to make these be free functions that take an AbstractElement, and then give AbstractElement some helper methods so that the caller doesn't have to care which it's dealing with. There are some FIXMEs here because PseudoElement doesn't have a CountersSet yet, and because the CountersSet currently uses a UniqueNodeID to identify counter sources, which doesn't support pseudo-elements.	2025-06-19 12:35:31 +01:00
Sam Atkins	ce380a59c7	LibWeb/DOM: Rename ElementReference to AbstractElement ... This isn't some kind of identifier, it's a handle on an actual Element or PseudoElement.	2025-06-19 12:35:31 +01:00
Tim Ledbetter	07b3b70a10	LibWeb: Return the correct computed value for opacity properties	2025-06-19 10:27:35 +02:00
Tim Ledbetter	269d5bb40e	LibWeb: Resolve percentages for opacity properties at parse time	2025-06-19 10:27:35 +02:00
Gingeh	e96338dd63	LibWeb: Don't play initially-paused animations	2025-06-18 17:17:29 +02:00
Aliaksandr Kalenik	6169e91994	LibWeb: Delete redundant GridFitContent class from track representation ... GridSize already supports the FitContent type, so there is no need to additionally wrap it in a GridFitContent class.	2025-06-18 15:51:10 +01:00
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	fa1e02e5d7	LibWeb: Allow calc() values in cubic-bezier() easing functions	2025-06-18 08:57:06 +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	7fe854c131	LibWeb/CSS: Link CalculationContext to new spec definition ... Corresponds to ad244f3413 There's nothing that we need to do differently I think, but it's nice to have a clear spec definition to refer to. :^)	2025-06-17 12:38:27 +01:00
Sam Atkins	a263ba78ed	LibWeb/CSS: Add FIXME that color-mix() now takes 1+ colors, not 2 ... Corresponds to 83c7bffe51	2025-06-17 12:38:27 +01:00
Sam Atkins	1435480d76	LibWeb/CSS: Add fixme for sRGB color interpolation ... Corresponds to a0a9886063	2025-06-17 12:38:27 +01:00
