Sam Atkins	326933cd93	LibWeb/CSS: Use CSS::URL for <url> and <paint> types	2025-04-30 17:38:38 +01:00
Sam Atkins	d301510ab2	Everywhere: Correct "FIMXE" typo	2025-04-30 17:38:38 +01:00
Tim Ledbetter	e7ae9c8ebf	LibWeb: Parse all as keyword in transition shorthand ... This ensures that the parsing of the `transition` shorthand property behaves in the same way as the `transition-property` longhand.4	2025-04-28 20:51:36 +02:00
Tim Ledbetter	04fde1c550	LibWeb: Ensure lang pseudoclass matches multiple segment subcodes	2025-04-28 11:29:30 +01:00
Tim Ledbetter	74c803c87b	LibWeb: Ensure |= value selector handles multiple segments correctly ... Previously, the `|=` would not compare strings containing `-` characters correctly because it would only compare the element attribute up to the first `-` character.	2025-04-28 11:29:30 +01:00
Tim Ledbetter	f854f644a7	LibWeb: Don't crash when interpolating non <number> scale values	2025-04-28 11:46:34 +02:00
Tim Ledbetter	8a398e7a88	LibWeb: Parse all transition-property value as keyword ... We were previously parsing this value, as a custom-ident, meaning that the code path for handling the `all` case wasn't being followed.	2025-04-27 09:49:00 +01:00
Andreas Kling	d8ea16d94e	LibWeb: Don't assume calc() simplification worked on invalid tree ... Fixes #4469	2025-04-25 16:55:05 +02:00
Timothy Flynn	ad34fdad48	LibWeb: Convert trivial attributes to FrozenArray	2025-04-25 16:43:43 +02:00
Andreas Kling	cf704cfbfc	LibWeb: Implement interpolation for CSS scale values ... And let's handle the 3rd (Z) scale parameter as well, while we're here. At least 242 new passes on WPT.	2025-04-25 14:08:12 +02:00
Timothy Flynn	fe6d8131ae	LibWeb: Return correct type from CSSNestedDeclarations::style ... We implement CSSStyleProperties so let's use it.	2025-04-25 08:48:29 +02:00
Andreas Kling	0553bcb35b	LibWeb: Simplify standalone CSS math functions when used outside calc() ... Math functions like abs(), clamp(), round(), etc, can be used by themselves in property values, without wrapping them in calc(). Before this change, we were neglecting to run calc simplification on the generated calculation node trees. By doing that manually after parsing a standalone math function, we score at least a couple hundred WPT points.	2025-04-24 20:38:00 +02:00
Andreas Kling	cf34a7bb32	LibWeb: Invalidate owner sheet on add/remove in CSSStyleProperties ... Fixes at least 2 WPT subtests.	2025-04-24 18:26:54 +02:00
Andreas Kling	1772adb600	LibWeb: Don't crash on non-finite values in CSS clamp() function ... Stops a WPT test from crashing, giving us 29 new subtest passes. :^)	2025-04-24 18:26:54 +02:00
Andreas Kling	2f76b24b89	LibWeb: Throw on deleting CSS @namespace rule in disallowed conditions ... Fixes one(!) WPT test :^)	2025-04-24 18:26:54 +02:00
Tim Ledbetter	fc1026984c	LibWeb: Don't crash when processing a transition with value none	2025-04-24 00:00:23 +02:00
Tim Ledbetter	64577ad704	LibWeb: Allow multiple values for the transition-duration property	2025-04-23 21:02:59 +01:00
Tim Ledbetter	1ca9f2a44d	LibWeb: Allow multiple values for the transition-delay property	2025-04-23 21:02:59 +01:00
Tim Ledbetter	c5f1f36119	LibWeb: Allow multiple values for transition-timing-function property	2025-04-23 21:02:59 +01:00
Tim Ledbetter	7a391f419a	LibWeb: Handle single value properties when normalizing transition lists ... Previously, if a transition property was not wrapped in a list, it would be replaced with the default value in `StyleComputer::compute_transitioned_properties`.	2025-04-23 21:02:59 +01:00
Tim Ledbetter	1f8f3804a3	LibWeb: Allow transition-property with multiple values	2025-04-23 21:02:59 +01:00
Sam Atkins	658569b533	LibWeb/CSS: Use CSSRule's context to parse new child rules ... Keep track of which CSSRule owns a CSSRuleList, and then use that to produce a stack of RuleContexts for the CSS Parser to use. There are certainly other places we should do this!	2025-04-23 10:55:45 +01:00
Sam Atkins	763b1b0ee2	LibWeb/CSS: Move RuleContext type out of Parser.h ... This was previously internal to the Parser, but we'd like to pass it in from outside.	2025-04-23 10:55:45 +01:00
Sam Atkins	9465492edf	LibWeb/CSS: Combine the CSSRuleList constructors	2025-04-23 10:55:45 +01:00
Sam Atkins	3d1665cc80	LibWeb/CSS: Parse nested declarations in insert_a_css_rule() ... The spec algorithm changed at some point to support nested declarations, but I only just noticed. The subtest regression is one we were passing incorrectly.	2025-04-23 10:55:45 +01:00
Sam Atkins	fa8bbfa6a5	LibWeb/CSS: Align declaration block parsing with the spec ... We have two different code paths that implement the "parse a CSS declaration block" algorithm, for properties and descriptors. COmbining them isn't straightforward, and doesn't seem especially useful.	2025-04-23 10:55:45 +01:00
Tim Ledbetter	8a20899382	LibWeb: Canonicalize color space when parsing color-mix() function ... This amounts to replacing the "xyz" color space with "xyz-d65".	2025-04-23 11:26:27 +02:00
Tim Ledbetter	04d7228c51	LibWeb: Implement interpolation of repeatable lists	2025-04-23 09:13:45 +01:00
Tim Ledbetter	0beb22f19e	LibWeb: Implement interpolation of edge values	2025-04-23 09:13:45 +01:00
Tim Ledbetter	6f5b107fcc	LibWeb: Resolve absolute calc() values in color functions ... Currently, `calc()` values with relative units are not handled correctly and will output an error to the console.	2025-04-22 12:20:26 +02:00
Tim Ledbetter	9cf04f40f6	LibWeb: Implement the color-mix() function ... This takes 2 color values and returns the result of mixing them by a given amount.	2025-04-22 12:19:51 +02:00
Aliaksandr Kalenik	8e2d1559ec	LibGfx: Join ScaledFont into Font ... Since ScaledFont is the only class inherited from Font we could simply merge them.	2025-04-21 09:51:16 +02:00
Andreas Kling	a6dfc74e93	LibWeb: Only set prototype once for object with IDL interface ... Before this change, we were going through the chain of base classes for each IDL interface object and having them set the prototype to their prototype. Instead of doing that, reorder things so that we set the right prototype immediately in Foo::initialize(), and then don't bother in all the base class overrides. This knocks off a ~1% profile item on Speedometer 3.	2025-04-20 18:43:11 +02:00
Tim Ledbetter	4283c73d02	LibWeb: Return correct computed value for lab-like and lch-like colors	2025-04-20 16:51:20 +02:00
Tim Ledbetter	e860dd4f65	LibWeb: Implement serialization of lch-like color values	2025-04-20 16:51:20 +02:00
Tim Ledbetter	5074d90888	LibWeb: Implement serialization of lab-like color values	2025-04-20 16:51:20 +02:00
Shannon Booth	f48b760011	LibWeb/CSS: Avoid URL validity check parsing CSS URLs	2025-04-19 07:18:43 -04:00
Andreas Kling	5df3838a80	LibWeb: Evaluate style sheet media rules immediately on insertion ... Before this change, we were waiting for Document to lazily evaluate sheet media and media rules. This often meant that we'd get two full-document style invalidations: one from adding a new style sheet, and one from the media queries changing state. By evaluating the rules eagerly on insertion, we coalesce the two invalidations into one. This reduces the number of full-document invalidations on Speedometer 3 from 51 to 34.	2025-04-19 01:14:02 +02:00
Andreas Kling	57809b1100	LibWeb: Skip dynamic_cast in CSSRGB after we already did a type check	2025-04-18 14:45:56 +02:00
Shannon Booth	3e17b1c9ae	LibWeb: Make Node::parent_element return GC::Ptr ... This is useful for people like myself who run with debug mode to more reliably get stacktraces without spinning up a debugger.	2025-04-18 10:49:02 +02:00
Andreas Kling	e1777f6e79	LibWeb: Make :hover invalidation logic reusable for all pseudo classes ... We achieve this by keeping track of all checked pseudo class selectors in the SelectorEngine code. We also give StyleComputer per-pseudo-class rule caches.	2025-04-17 19:45:55 +02:00
Andreas Kling	ed35f9e7c2	LibWeb: Remove unused MatchingRule::must_be_hovered flag ... This was a vestige from an earlier version of hover selector work avoidance optimizations.	2025-04-17 19:45:55 +02:00
Tim Ledbetter	ca200142e9	LibWeb: Don't construct stylesheet when modifying CSSStyleSheet rules ... Previously, `CSSStyleSheet.replace()` and `CSSStyleSheet.replaceSync()` parsed the given CSS text into a temporary stylesheet object, from which a list of rules was extracted. Doing this had the unintended side-effect that a fetch request would be started if the given CSS text referenced any external resources. This fetch request would cause a crash, since the temporary stylesheet object didn't set the constructed flag, or constructor document. We now parse the given CSS text as a list of rules without constructing a temporary stylesheet.	2025-04-16 22:03:12 +01:00
