Callum Law	36e2d25efa	LibWeb: Parse grid track placements closer to spec ... This brings parsing of grid-row-* and grid-column-* properties (and their associated shorthands) more inline with spec. Changes: - Only set omitted properties for combined-value shorthands (e.g. `grid-row: a` rather than `grid-row: a / b`) if the single value is `<custom-ident>`. - `[ [ <integer [-∞,-1]> | <integer [1,∞]> ] && <custom-ident>? ]`: - Properly resolve `calc`s for `<integer>` that rely on compute-time information. - `[ span && [ <integer [1,∞]> || <custom-ident> ] ]` - Allow `calc`s for `<integer>` - Allow `<custom-ident>` There is still work to be done to properly use these parsed values. Gains us 46 WPT tests.	2025-07-08 17:26:16 +01:00
Sam Atkins	e74afec9c5	LibWeb: Capitalize "No Popover state" consistently ... Corresponds partly to 8035a256bf	2025-07-08 17:08:39 +01:00
Sam Atkins	d9aeffa302	LibWeb/CSS: Adjust grammar definitions ... Corresponds to: e2903b127e 1b4ea44fc8	2025-07-08 10:24:49 +01:00
Sam Atkins	202c55bf28	LibWeb/CSS: Implement the :state(foo) pseudo-class ... This matches custom elements that have `foo` in their custom states set. The 2 test failures here are because we don't support `::part()` yet.	2025-07-04 18:10:28 +01:00
Sam Atkins	5387c923ca	LibWeb/CSS: Use first_is_one_of() in can_selector_use_fast_matches() ... Makes things a bit easier to read. I've also sorted the pseudo-classes.	2025-07-04 18:10:28 +01:00
Sam Atkins	bc94431b99	IDLGenerators: Add a callback for when a setlike's set is modified ... For simplicity, this requires that the setlike Foo class has a `void on_set_modified_from_js(Badge<Bindings::FooPrototype>)` method. This will be called after the set is modified from a generated `add()`, `delete()`, or `clear()` method.	2025-07-04 18:10:28 +01:00
Gingeh	1b7323fc2d	LibWeb: Interpolate legacy colors in sRGB	2025-07-04 15:28:08 +01:00
Callum Law	778759517e	LibWeb: Support calcs which resolve to numbers as hue values in colors ... Gains us 5 new WPT tests.	2025-07-04 13:18:55 +01:00
Callum Law	9ab7c5d08d	LibWeb: Support relative lengths in calc color values ... Gains us ~40 WPT tests.	2025-07-04 13:18:55 +01:00
Callum Law	62d138ebf7	LibWeb: Allow passing a resolution context to CSSStyleValue::to_color ... This will be used for resolving any calculated style values within the various `CSSColorValue` sub-classes. No functionality changes.	2025-07-04 13:18:55 +01:00
Callum Law	b468923372	LibWeb: Allow creating Length::ResolutionContext with provided root ... Previously we could not create a `Length::ResolutionContext` using the `for_layout_node` method if the provided node's document did not have a layout node. We now provide a workaround for this in the case that the provided layout is that root layout node. This is useful for instance if we want to create a length resolution context when calling `NodeWithStyle::apply_style` on the root node.	2025-07-04 13:18:55 +01:00
Timothy Flynn	62d9a84b8d	AK+Everywhere: Replace custom number parsers with fast_float ... Our floating point number parser was based on the fast_float library: https://github.com/fastfloat/fast_float However, our implementation only supports 8-bit characters. To support UTF-16, we will need to be able to convert char16_t-based strings to numbers as well. This works out-of-the-box with fast_float. We can also use fast_float for integer parsing.	2025-07-03 09:51:56 -04:00

Tim Ledbetter	af60e36122	LibWeb/CSS: Don't remove whitespace early when parsing descriptor values	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

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

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

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
