Sam Atkins	59e8a669de	LibWeb/CSS: Unify code in StyleComputer::cascade_declarations()	2025-05-14 11:46:47 +01:00
Sam Atkins	d1dadd43a1	LibWeb/CSS: Implement guaranteed-invalid value ... This is a special value produced when var/attr substitution fails, and is also the initial value for custom properties.	2025-05-14 11:46:47 +01:00
Sam Atkins	804c1eeeed	LibWeb/CSS: Remove double set_property_expanding_shorthands() call ... If `value` was UnresolvedStyleValue, we'd attempt to `set_property...()` with its resolved value, then call that again with the original UnresolvedStyleValue. For any other kind of `value`, we'd simply call call `set_property...()` twice with the same parameters.	2025-05-14 11:46:47 +01:00
Sam Atkins	ded3c95da5	LibWeb/CSS: Remove unused FontVariant style value type	2025-05-14 11:46:47 +01:00
Sam Atkins	475788732f	LibWeb/CSS: Remove outdated FIXME ... This method no longer sets anything to `initial`.	2025-05-14 11:46:47 +01:00
Timothy Flynn	7280ed6312	Meta: Enforce newlines around namespaces ... This has come up several times during code review, so let's just enforce it using a new clang-format 20 option.	2025-05-14 02:01:59 -06:00
Psychpsyo	31301ef08b	LibWeb: Add support for trees of pseudo-elements ... This is needed for CSS view transitions.	2025-05-13 12:38:42 +01:00
Tim Ledbetter	03e34db9f8	LibWeb: Interpolate the content-visibility property correctly	2025-05-13 11:24:05 +01:00
Tim Ledbetter	882ad4726e	LibWeb: Interpolate the visibility property correctly	2025-05-13 11:24:05 +01:00
Sam Atkins	fbdef98307	LibWeb: Dump CSSDescriptors in a generic way ... This replaces the need for bespoke (and verbose) dumping for each at-rule that has descriptors.	2025-05-08 16:21:32 +01:00
Sam Atkins	0925a32558	LibWeb/CSS: Extract a CSSDescriptors base class ... This holds the boilerplate that's needed by any CSSStyleDeclaration subclass that holds Descriptors. CSSFontFaceDescriptors now only has to worry about initialization and its own exposed properties.	2025-05-08 16:21:32 +01:00
Jelle Raaijmakers	c56f7d9cde	LibWeb: Invalidate sibling style for :only-child and :*-of-type ... After f7a3f785a8, sibling nodes' styles were no longer invalidated after a node was removed. This reuses the flag for `:first-child` and `:last-child` to indicate that a node's style might be affected by any structural change in its siblings. Fixes #4631. Resolves the `:only-child` ACID3 failure as documented in #1231.	2025-05-07 14:55:12 +03:00
Timothy Flynn	0da7441b9b	LibWeb: Set the initiator type for script-initiated CSS requests ... Similar to other ad-hoc behavior in this method, we need to handle requests which are not associated with a style sheet. For example: <script> const element = document.createElement('div'); element.style['background'] = 'url(https://foo.com/img.png)'; document.body.appendChild(element); </script> Will not be associated with a style sheet. This is needed to ensure we fire a PerformanceResourceTiming event for this resource load. This is not currently testable in CI, as this event is also gated by HTTP/S requests.	2025-05-06 17:37:34 +01:00
Mark Langen	6cbb5d2785	LibWeb: Parse and propagate touch-action CSS property ... Co-authored-by: Sam Atkins <sam@ladybird.org>	2025-05-06 12:22:01 +01:00
Bastiaan van der Plaat	58b735010b	LibWeb: Add -webkit-box-* legacy CSS property aliases	2025-05-05 23:36:31 +02:00
Jelle Raaijmakers	71665fa504	LibWeb: Scale font size by 1.15 for line-height: normal ... Browsers such as Chrome and Firefox apply an arbitrary scale to the current font size if `normal` is used for `line-height`. Firefox uses 1.2 while Chrome uses 1.15. Let's go with the latter for now, it's relatively easy to change if we ever want to go back on that decision. This also requires updating the expectations for a lot of layout tests. The upside of this is that it's a bit easier to compare our layout results to other browsers', especially Chrome.	2025-05-05 13:15:56 +02:00
Psychpsyo	7c36a82129	LibWeb: Improve parsing for the CSS contain property ... This makes us actually respect the grammar and nets us a couple extra WPT passes in the parsing section.	2025-05-04 22:24:26 +01:00
Sam Atkins	de6df6f403	LibWeb/CSS: Parse and use CSS URL request modifiers	2025-05-03 23:22:40 +01:00
Sam Atkins	a1fb34d7f2	LibWeb/CSS: Alphabetize Enums.json	2025-05-03 23:22:40 +01:00
Sam Atkins	560317b3d0	LibWeb/CSS: Update spec comment in calc() simplification algorithm ... This was corrected in 8bcf3ada9e	2025-05-03 14:54:33 +01:00
Sam Atkins	1cb1526178	LibWeb/CSS: Remove document-URL hack from create_a_style_sheet() ... We no longer need this, because we don't complete URLs during parsing, and the location is set elsewhere when needed.	2025-05-03 12:01:43 +01:00
Sam Atkins	bc1d323ba0	LibWeb/CSS: Remove URL parameter to the CSS Parser ... We no longer complete any URLs during parsing.	2025-05-03 12:01:43 +01:00
Sam Atkins	9e2e796f2d	LibWeb/CSS: Use CSS::URL for font-fetching ... ParsedFontFace and FontLoader now both keep track of which CSSStyleSheet (if any) was the source of the font-face, so the URLs can be completed correctly.	2025-05-03 12:01:43 +01:00
Sam Atkins	14fb567a0f	LibWeb/CSS: Stop overwriting style sheet location after construction	2025-05-03 12:01:43 +01:00
Sam Atkins	7a4854732a	LibWeb/CSS: Make CSS::URL formattable	2025-05-03 12:01:43 +01:00
Sam Atkins	efad6e96aa	LibWeb/CSS: Set CSSFontFaceDescriptors' parent rule	2025-05-03 12:01:43 +01:00
Sam Atkins	ffc01626f7	LibWeb/CSS: Load fonts using fetch ... Convert FontLoader to use fetch_a_style_resource(). ResourceLoader used to keep its downloaded data around for us, but fetch doesn't, so we use Gfx::Typeface::try_load_from_temporary_memory() so that the font has a permanent copy of that data.	2025-05-03 12:01:43 +01:00
Sam Atkins	f76f8dcce1	LibWeb/CSS: Return the FetchController from fetch_a_style_resource()	2025-05-03 12:01:43 +01:00
Sam Atkins	6b762331df	LibGfx: Rename WOFF[2]::try_load_from_externally_owned_memory() ... Typeface::try_load_from_externally_owned_memory() relies on that external owner keeping the memory around. However, neither WOFF nor WOFF2 do so - they both create separate ByteBuffers to hold the TTF data. So, rename them to make it clearer that they don't have any requirements on the byte owner.	2025-05-03 12:01:43 +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	c0f9b11070	LibWeb: Parse oblique font-style with an angle value	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
Psychpsyo	82387e2127	LibWeb: Avoid changing button border color on disable/hover	2025-04-30 20:13:14 +01:00
Tim Ledbetter	c72d5943e6	LibWeb: Support interpolating translate values	2025-04-30 19:36:56 +02:00
Tim Ledbetter	27baaa13e9	LibWeb: Support parsing and serializing 3D translate values	2025-04-30 19:36:56 +02:00
Tim Ledbetter	d804f1311c	LibWeb: Don't serialize scale z value if it is 1	2025-04-30 19:36:56 +02:00
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
