Tim Ledbetter	a8d5758777	LibWeb: Only resolve transform-origin keywords for the computed value ... Previously, we were resolving these keywords at parse time, which gave an incorrect serialization of the specified value.	2025-06-15 16:01:54 +02:00

Tim Ledbetter	028bcd3d67	LibWeb/CSS: Backtrack the parser if a property does not accept a value	2025-06-14 08:22:56 +02:00
Tim Ledbetter	26293114d8	LibWeb/CSS: Treat repeated text-decoration-line values as invalid	2025-06-14 08:19:47 +02:00
Callum Law	d31a58a7d6	LibWeb: Add support for the 'all' CSS property ... The "longhands" array is populated in the code generator to avoid the overhead of manually maintaining the list in Properties.json There is one subtest that still fails in 'cssstyledeclaration-csstext-all-shorthand', this is related to us not maintaining the relative order of CSS declarations for custom vs non-custom properties.	2025-06-12 15:25:35 +01:00
Tim Ledbetter	e2d0d8e2b9	LibWeb/CSS: Implement the scrollbar-color property ... This allows the user to set the scrollbar thumb and track colors.	2025-06-02 00:17:51 +02:00
Lucien Fiorini	0fcb574041	LibGfx+LibWeb: Turn Gfx::Filter into a SkImageFilter wrapper	2025-06-01 23:22:10 +02:00
Callum Law	94f5a51820	LibWeb: Convert white-space CSS property to shorthand ... This exposed a few bugs which caused the following tests to behave incorrectly: - `tab-size-text-wrap.html`: This previously relied on a bug where we incorrectly treated `white-space: pre` as allowing text wrapping. The fix here is to implement the text-wrap CSS shorthand property. - `execCommand-preserveWhitespace.html`: We don't correctly serialize shorthand properties. This is covered by an existing FIXME in `CSSStyleProperties::serialized()` - `white-space-shorthand.html`: The last 5 subtests here fail as we don't correctly handle shorthand properties in `CSSStyleProperties::remove_property()`. This is covered by an existing FIXME in said function.	2025-05-29 12:04:28 +02:00
Callum Law	9480b1fc5c	LibWeb: Parse and propagate white-space-trim CSS property	2025-05-29 12:04:28 +02:00
Sam Atkins	f5825ab18c	LibWeb/CSS: Stop erasing font-variant-css2 value in font shorthand ... We don't want to reset the values of `font-variant-*` here, as that will override whatever our parsed font-variant-css2 was, so stop doing that. Also, font-stretch is mentioned in the spec, but it's a legacy name alias for font-width, so we don't need to do anything for it. Gets us 319 WPT passes!	2025-05-23 19:39:23 +01:00
Sam Atkins	d9a8349d8c	LibWeb/CSS: Parse font-variant and font-weight parts of font properly ... These are not the same as parsing their properties, but are limited to a small set of keywords each. The easiest way to handle these is parsing them directly here. Update some comments while I'm here.	2025-05-23 19:39:23 +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
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
Tim Ledbetter	c0f9b11070	LibWeb: Parse oblique font-style with an angle value	2025-05-03 12:05:22 +02:00
Bastiaan van der Plaat	832bb978f5	LibWeb: Reject CSS values with unprocessed tokens / extra semicolons	2025-05-02 11:10:02 +01:00
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	27baaa13e9	LibWeb: Support parsing and serializing 3D translate values	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
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	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
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	1f8f3804a3	LibWeb: Allow transition-property with multiple values	2025-04-23 21:02:59 +01:00
Andrew Kaster	6d11414957	LibWeb: Make storage of CSS::StyleValues const-correct ... Now we consistently use `RefPtr<StyleValue const>` for all StyleValues.	2025-04-16 10:41:44 -06:00
Sam Atkins	a7f7c2a821	LibWeb/CSS: Teach OpenTypeTaggedStyleValue to serialize without "1"	2025-04-07 10:00:21 +01:00
Tim Ledbetter	e73438e82c	LibWeb: Clamp grayscale, invert, filter and opacity filter values to 1	2025-04-04 17:12:47 +01:00
Tim Ledbetter	61f76c7ec5	LibWeb: Set color filter value to 1 if omitted	2025-04-04 17:12:47 +01:00
Sam Atkins	79093291b5	LibWeb/CSS: Un-template parse_comma_separated_value_list() ... This doesn't need to be a template. Changing it means we can use it from any FooParsing.cpp file, and also move it ValueParsing.cpp where it belongs.	2025-04-04 10:40:32 +01:00
Glenn Skrzypczak	9973b01848	LibWeb/CSS: Improved implementation of background-blend-mode ... This is a improved version of a73cd88f0c The old commit was reverted in 552dd18696 The new version only paints an element into a new layer if background blend modes other than normal are used. The rasterization performance of most websites should therefore not suffer. Co-Authored-By: Alexander Kalenik <kalenik.aliaksandr@gmail.com>	2025-04-01 13:38:00 +02:00
Aliaksandr Kalenik	552dd18696	Revert "LibWeb/CSS: Implement 'background-blend-mode'" ... This reverts commit a73cd88f0c. Emitting SaveLayer for each paintable made rasterization a lot slower on every website because now Skia has to allocate enormous amounts of temporary surfaces. Let's revert it for now and figure how to implement it with less aggressive SaveLayer usage.	2025-03-28 16:48:03 +00:00
Glenn Skrzypczak	a73cd88f0c	LibWeb/CSS: Implement 'background-blend-mode' ... This implements the 'background-blend-mode' CSS property.	2025-03-28 09:41:06 +00:00
Sam Atkins	ef3a2bf907	LibWeb/CSS: Move functions for detecting var()/attr() into Token types ... This makes them accessible outside of PropertyParsing.cpp (which will be useful if/when descriptors can include them). I've also renamed them to use the correct term: "arbitrary substitution function".	2025-03-28 09:15:02 +00:00
Sam Atkins	f8536fc48a	LibWeb/CSS: Split out <family-name> parsing ... This type is used individually elsewhere in the spec. This also lets us separate out the `<generic-family>` type.	2025-03-25 07:53:59 +00:00
Tim Ledbetter	2672fe99b7	LibWeb: Set correct longhands if grid-area subproperties are omitted	2025-03-20 16:59:27 +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
Tim Ledbetter	dc58c11217	LibWeb: Reject invalid background-position-* property values	2025-03-14 15:07:57 +00:00
Tim Ledbetter	5559c3cb4f	LibWeb/CSS: Parse <single-transition-property> as a <custom-ident> ... The specification also treats a transition name of `none` as invalid.	2025-03-14 08:52:25 +01:00
Tim Ledbetter	6298ec6be4	LibWeb: Validate time values when parsing transition value	2025-03-14 08:52:25 +01:00
Tim Ledbetter	b80c0d2114	LibWeb/CSS: Reject invalid grid track placement property values	2025-03-14 08:50:04 +01:00
Tim Ledbetter	ad4ade3f07	LibWeb/CSS: Disallow invalid <counter-name> values ... We now parse `<counter-name>` values as a `<custom-ident>`. This disallows `default` and CSS-wide keywords as counter names. The specification additionally disallows `none` as a counter name.	2025-03-13 05:23:19 +00:00
Tim Ledbetter	249de20343	LibWeb/CSS: Don't allow negative values in filter functions	2025-03-12 09:06:16 +00:00
