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	d804f1311c	LibWeb: Don't serialize scale z value if it is 1	2025-04-30 19:36:56 +02:00
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
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
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
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
Jelle Raaijmakers	6f800caeaa	LibWeb: Don't mess up the order of nodes when wrapping inline contents ... Whenever we introduce a block element in a container that at that point has only had inline children, we create an anonymous wrapper for all the inline elements so we can keep the invariant that each container contains either inline or non-inline children. For some reason, we ignore all the out-of-flow nodes since they are layed out separately and it was thought that this shouldn't matter. However, if we are dealing with inline blocks and floating blocks, the order of the inline contents _including_ out-of-flow nodes becomes very important: floating blocks need to take the order of nodes into account when positioning themselves. Fix this by simply hoisting the out-of-flow nodes into the anonymous wrapper as well. Fixes the order of blocks in #4212. The gap is still not present.	2025-04-24 19:12:50 +02:00
Andreas Kling	d33445a4ea	LibWeb: Notify ObservableArray observer about deletions in clear() ... Another +1 WPT subtest!	2025-04-24 18:26:54 +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	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	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	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
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	16e83f0b35	Tests: Remove some animation tests from the ignore list ... These tests are relevant to the fixes being made in later commits	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
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
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
Sam Atkins	9f333c424c	LibWeb/CSS: Ensure a font source format() only contains one string/ident	2025-04-15 21:40:41 +02:00
Sam Atkins	52a4259ef2	LibWeb/CSS: Make @font-face src parsing more forgiving ... As noted in the spec, an invalid (or unsupported) font source should not make the `src` declaration invalid.	2025-04-15 21:40:41 +02:00
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	0f42d5ec3e	LibWeb/CSS: Don't resolve @import URLs until they are used ... The regression in the "conditional-CSSGroupingRule" test is we now fail the "inserting an `@import`" subtests differently and the subtests aren't independent. Specifically, we don't yet implement the checks in `CSSRuleList::insert_a_css_rule()` that reject certain rules from being inserted. Previously we didn't insert the `@import` rule because we failed to parse its relative URL. Now we parse it correctly, we end up inserting it.	2025-04-09 18:45:57 +01:00
