Psychpsyo	dbece92637	LibWeb: Make elements with 'opacity: 0' respond to hit-testing	2025-05-07 01:45:07 +03:00
Sam Atkins	09b508d8e8	Tests: Import some URL-related WPT tests	2025-05-03 23:22:40 +01:00
Tim Ledbetter	23009779e1	LibWeb: Interpolate font-style values correctly ... These are interpolated by computed value, except a value of `normal` is treated as `oblique 0deg`.	2025-05-03 12:05:22 +02:00
Tim Ledbetter	542c3cbe51	LibWeb: Implement the transition-behavior CSS property ... This specifies whether transitions should be started for transitions whose animation behavior is discrete.	2025-05-02 11:07:19 +01:00
Tim Ledbetter	c1a3b95176	LibWeb: Set transition property name when firing transition events	2025-04-29 12:23:31 +02:00
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
Andreas Kling	d8ea16d94e	LibWeb: Don't assume calc() simplification worked on invalid tree ... Fixes #4469	2025-04-25 16:55:05 +02:00
Andreas Kling	4f4b43f1d2	Tests: Import WPT test for CSS scale interpolation	2025-04-25 14:08:12 +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	fbb3b06462	LibWeb: Don't assume table caption box wants to create a BFC ... Instead, use the generic create_independent_formatting_context_if_needed so that unusual situations like image-as-table-caption don't crash. This logic clearly needs more work, but let's at least do better than crashing. This gives us 26 new subtest passes on WPT.	2025-04-24 18:26:54 +02:00
Andreas Kling	f7a7cd9b2b	LibWeb: Prevent infinite recursion on abspos w/ intrinsic max-size ... We were incorrectly deciding that abspos elements shouldn't treat many max-width and max-height values as `none`. My best understanding is that this was a hack in 2023 for an issue that has been solved since then. By removing the incorrect short-circuit, we stop at least one WPT test from crashing due to infinite recursion and get ourselves +34 passes.	2025-04-24 18:26:54 +02:00
Andreas Kling	e5d62e9915	LibWeb: Track whether HTMLLinkElement was enabled when created by parser ... This information is needed by the script-blocking style sheet logic, and its absence was causing a WPT test to crash.	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	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	1f8f3804a3	LibWeb: Allow transition-property with multiple values	2025-04-23 21:02:59 +01:00
Tim Ledbetter	04d7228c51	LibWeb: Implement interpolation of repeatable lists	2025-04-23 09:13:45 +01:00
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
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	5074d90888	LibWeb: Implement serialization of lab-like color values	2025-04-20 16:51:20 +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
Andreas Kling	e068ff5a5d	LibWeb: Always store ComputedProperties, even if no invalidations ... Before this change, we'd skip storing the new ComputedProperties in Element::recompute_style() if there was no invalidation needed. This caused us to lose the information about which properties are inherited and/or important (which is also carried by ComputedProperties, but doesn't affect invalidation). Consequently, we'd then fail to recompute inherited styles, since that mechanism depends on this data. The fix is simply to always store the new ComputedProperties.	2025-04-13 00:43:49 +02:00
Andreas Kling	2aa6d7636c	LibWeb: Invalidate sheet owners after mutating cssText of its rules ... This fixes one source of flakiness on WPT (of many) where we wouldn't recompute style after programmatically altering the contents of a style sheet, but instead had to wait for something else to cause invalidation.	2025-04-12 14:15:57 +01:00
Tim Ledbetter	f07a3fe6da	LibWeb: Use discrete interpolation for degenerate ratios ... Degenerate ratios cannot be interpolated.	2025-04-11 11:38:05 +01:00
Tim Ledbetter	b3980d40f7	LibWeb: Round to the nearest integer when interpolating integer values	2025-04-11 11:31:54 +01:00
Sam Atkins	1d9902e22c	Tests: Import some @import tests	2025-04-09 18:45:57 +01:00
Tim Ledbetter	a97fe3123d	LibWeb: Don't convert color functions to RGB when resolving color values	2025-04-09 12:11:33 +01:00
Tim Ledbetter	2a17d6d449	LibWeb: Set clip-path animation type to by-computed-value	2025-04-09 09:02:59 +01:00
Tim Ledbetter	408f9f3dde	LibWeb: Disallow "default" as a <family-name> identifier ... This commit disallows "default" as a font-family name, when the name is not quoted because unquoted names are treated as custom-idents, for which the name "default" is not allowed.	2025-04-07 12:14:29 +01:00
Tim Ledbetter	263cb3f8ca	LibWeb/CSS: Remove unnecessary shorthand serialization special cases ... The serialization of these properties is improved by using the new default behavior.	2025-04-07 11:38:56 +01:00
Tim Ledbetter	3186adeaa1	LibWeb/CSS: Don't serialize longhands which match their initial values ... Shorthand subproperties that match their initial values are now excluded from serialization, by default. Properties where this behavior is not desired, like `gap`, are special-cased.	2025-04-07 11:38:56 +01:00
Tim Ledbetter	32812f5db0	LibWeb: Return absolutized computed value for outline width property	2025-04-05 12:54:22 +02:00
Tim Ledbetter	8738987e44	LibWeb: Return absolutized computed value for border width properties	2025-04-04 23:45:06 +02:00
Tim Ledbetter	46411295d6	LibWeb: Serialize drop-shadow filter properties in canonical order	2025-04-04 17:12:47 +01:00
Tim Ledbetter	c941170e5a	LibWeb: Invalidate document style when media rules are changed ... This ensures that new media rules are always produce the correct result when evaluated.	2025-04-04 10:10:43 +02:00
Sam Atkins	bd7a08da3b	Tests: Reimport font-stretch tests as font-width ... Corresponds to 7c0c4806bb	2025-04-02 14:55:27 +01:00
Tim Ledbetter	7b0b6e7493	LibWeb/CSS: Make empty GridTrackSize value serialize to "none" ... This is the default value of the `grid-template-rows` and `grid-template-columns` properties.	2025-03-22 17:33:37 +01:00
Tim Ledbetter	cbf47abd24	LibWeb/CSS: Set the initial value of the appearance property to "none"	2025-03-22 17:05:17 +01:00
Tim Ledbetter	ecd6636b3e	LibWeb/CSS: Use "0s" as the initial value for animation-duration	2025-03-22 17:04:33 +01:00
Tim Ledbetter	d0be5a0cdf	LibWeb: Preserve unit when serializing time values ... Previously, when serializing a time value, we would always convert it to seconds. We now canonicalize the time value only when serializing its computed value.	2025-03-20 16:59:27 +00:00
Tim Ledbetter	54351e7327	LibWeb: Use shortest serialization for shorthands with repeated values ... For shorthands where all the values are repeated, we now only output the value once.	2025-03-20 14:30:55 +01:00
Tim Ledbetter	85728b297f	LibWeb: Ensure the shortest serialization is used for border-radius ... This implementation also fixes an issue where the individual components of the `border-radius` shorthand were always assumed to be of type `BorderRadiusStyleValue`, which could lead to a crash when CSS-wide keywords were used.	2025-03-18 21:55:06 +01:00
Aliaksandr Kalenik	394073f611	LibWeb: Rename internals.signalTextTestIsDone() to signalTestIsDone() ... In upcoming change this function will be used for ref-tests as well.	2025-03-18 20:09:46 +01:00
Tim Ledbetter	01d1a9528b	LibWeb: Calculate the correct resolved value for inset properties ... This improves the output of `getComputedStyle()` for the `top`, `bottom`, `left` and `right` properties, where the used value is now returned rather than the computed value, where applicable."	2025-03-18 09:27:51 +00:00
Tim Ledbetter	e011ddd368	LibWeb/CSS: Parse border-block-* properties ... This doesn't currently honor `writing-mode`, `direction` and `text-orientation`.	2025-03-14 16:09:10 +00:00
Tim Ledbetter	cd1bba353a	LibWeb/CSS: Parse border-inline-* properties ... This doesn't currently honor `writing-mode`, `direction` and `text-orientation`.	2025-03-14 16:09:10 +00:00
Tim Ledbetter	18cccd7633	LibWeb/CSS: Don't allow negative values in border-radius property	2025-03-14 15:07:57 +00:00
Tim Ledbetter	632fc73643	LibWeb/CSS: Don't allow negative border radius in box-shadow property	2025-03-14 15:07:57 +00:00
