Callum Law	f49cf75d44	LibWeb: Don't pass unnecessary PropertyComputationDependencies struct ... Since we now have access to the `AbstractElement` through the `ComputationContext` we can just set the flag that this element relies on tree counting functions directly, no need to pass this struct around.	2025-10-22 00:01:30 +02:00
Callum Law	2404f95e03	LibWeb: Invalidate style for tree counting functions when required ... We mark any element that relies on tree counting functions as needing a style update when a sibling is inserted/removed.	2025-10-20 16:12:08 +01:00
Sam Atkins	0afa93e639	LibWeb/CSS: Add a Property -> CalculationContext factory method ... We have this code duplicated in multiple places, and we'll want to handle registered custom properties too at some point, so wrap it in a reusable `CalculationContext::for_property()` method. Noticed while doing this that ValueParsingContext will eventually need to take a PropertyNameAndID, not a PropertyID, so I've added a FIXME.	2025-10-13 09:59:38 +01:00
Callum Law	102edf638d	LibWeb: Support interpolation of SuperellipseStyleValue	2025-10-09 10:23:20 +01:00
Callum Law	25192d3c20	LibWeb: Store BorderRadiusStyleValue sub-values directly ... Storing these within LengthPercentage is unnecessary	2025-10-07 10:50:01 +01:00
Callum Law	2ebf446cbf	LibWeb: Store BackgroundSizeStyleValue sub-values directly ... Storing these within LengthPercentage is unnecessary	2025-10-07 10:50:01 +01:00
Callum Law	309ff33278	LibWeb: Add convenience from_style_value for LengthPercentage{OrAuto}	2025-10-07 10:50:01 +01:00
Tim Ledbetter	b64cb89b9d	LibWeb: Implement compositing of font-variation-settings values	2025-09-26 11:20:54 +01:00

Tim Ledbetter	d18d40f7b9	LibWeb: Handle interpolation of grid track size lists ... This allows the `grid-template-rows` and `grid-template-columns` properties to be correctly interpolated.	2025-09-26 11:15:08 +01:00
Tim Ledbetter	436e9c317a	LibWeb: Extract commonly used interpolation lambdas into methods	2025-09-26 11:15:08 +01:00
Callum Law	b80e6a4d30	LibWeb: Rename get_inherit_value to get_non_animated_inherit_value ... This more acurately represents what it does.	2025-09-19 10:06:33 +01:00
Tim Ledbetter	9b15517052	LibWeb: Apply composite operator to keyframe effects	2025-09-18 16:46:06 +01:00
Callum Law	c3a78d2884	LibWeb: Don't include spread distance when serializing text-shadow ... We shouldn't include spread distance when serializing `text-shadow` as it is not supported unlike `box-shadow` - to achieve this we store whether this is a text or box shadow within the ShadowStyleValue and serialize appropriately.	2025-09-18 15:21:22 +01:00
Tim Ledbetter	f5fd6338d5	LibWeb: Handle interpolation of mixed-type LengthPercentages	2025-09-15 10:41:01 +01:00

Tim Ledbetter	19577b966e	LibWeb: Implement interpolation of border-image-slice style values	2025-09-13 12:05:19 +02:00
Sam Atkins	0293176429	LibWeb/CSS: Take AbstractElement in StyleComputer::get_*_inherit_value()	2025-09-11 18:45:35 +02:00
Sam Atkins	b3e32445d3	LibWeb/CSS: Use generated FooUnit types instead of Foo::Type ... I've also renamed the `m_type` and `type()` members to be `m_unit` and `unit()` instead, to match what they actually are.	2025-09-11 17:06:44 +01:00
Tim Ledbetter	bf8b8c260a	LibWeb: Simplify interpolation of mixed percentage-dimension values	2025-09-11 06:10:23 +01:00
Tim Ledbetter	9c062d9d4e	LibWeb: Improve interpolation of mixed percentage-dimension values ... If we are interpolating between a dimension and a percentage value and the dimension component is 0, we now return a percentage value rather than a `calc()` value.	2025-09-10 17:00:20 +01:00
Callum Law	5ed3b2ed16	LibWeb: Support interpolation of CalculatedStyleValue ... We also support interpolating from a CalculatedStyleValue to a compatible dimension or percentage style value. This also brings with it a couple of improvements in how we handle interpolation between mixed dimension and percentage types in terms of: - Proper simplification of the resulting calc() - Improved handling of interpolation outside the 0-1 range	2025-09-08 11:58:44 +01:00
Tim Ledbetter	fa6c7959ff	LibWeb: Pass calculation context by const reference	2025-09-07 14:50:36 +01:00
Tim Ledbetter	96b628fe21	LibWeb: Clamp interpolated values to their accepted range	2025-09-07 14:50:36 +01:00
Sam Atkins	04622f3940	LibWeb/CSS: Use LengthPercentageOrAuto for background sizes ... ...instead of `auto` Lengths. This also fixes interpolating between two `auto` `<bg-size>`s, which fixes a lot of animation tests for both `background-size` and `mask`.	2025-09-04 13:31:24 +01:00
Sam Atkins	9b27aaa00c	LibWeb/CSS: Use LengthOrAuto for clip rects	2025-09-04 13:31:24 +01:00
Tim Ledbetter	cb1a1a5cb5	LibWeb: Replace is<T>() with as_if<T>() where possible	2025-08-25 18:45:00 +02:00
Sam Atkins	5bdc2981e3	LibWeb/CSS: Rename CSSNumericType to NumericType ... The CSSNumericType defined in the spec is a simple dictionary which is only used for OM purposes. This NumericType class is used internally and matches the more abstract definition of a "type".	2025-08-22 09:48:30 +01:00
norbiros	783ae44462	LibWeb: Fix color interpolation by premultiplying alpha ... The current Color::interpolate_color method does not follow the specs properly. Started improving it by handling premultiplied alpha in color interpolation. Only one WPT test covers this (color-transition-premultiplied), which we currently pass due to a different approach in Color.mixed_with.	2025-08-14 11:09:05 +02:00
Callum Law	ed6cac89b9	LibWeb: Discard inaccuracies when interpolating rotate	2025-08-12 14:35:02 +01:00
Sam Atkins	6cad3f1921	LibWeb/CSS: Rename CSSColorValue -> ColorStyleValue ... The typed-om class will be a separate thing.	2025-08-08 15:19:03 +01:00
Sam Atkins	7157d19f56	LibWeb/CSS: Separate IntegerSV and NumberSV from CSSUnitValue ... This inheritance exists for typed-om classes, but StyleValues aren't typed-om. Somehow this makes our z-index interpolation slightly more correct. 🎉	2025-08-08 15:19:03 +01:00
Sam Atkins	4e92ab52e3	LibWeb/CSS: Rename CSSKeywordValue -> KeywordStyleValue ... The typed-om CSSKeywordValue will need to be a separate class.	2025-08-08 15:19:03 +01:00
Sam Atkins	c57975c9fd	LibWeb: Move and rename CSSStyleValue to StyleValues/StyleValue.{h,cpp} ... This reverts 0e3487b9ab. Back when I made that change, I thought we could make our StyleValue classes match the typed-om definitions directly. However, they have different requirements. Typed-om types need to be mutable and GCed, whereas StyleValues are immutable and ideally wouldn't require a JS VM. While I was already making such a cataclysmic change, I've moved it into the StyleValues directory, because it *not* being there has bothered me for a long time. 😅	2025-08-08 15:19:03 +01:00
Callum Law	a1037e28d6	LibWeb: Improve support for CalculatedStyleValue in scale ... - Properly serialize CalculatedStyleValue components - Allow CSV to be the 'Z' component in interpolated value Gains us 52 WPT tests	2025-08-08 09:45:00 +01:00
Callum Law	39fdcbc526	LibWeb: Improve support for CalculatedStyleValue in translate ... - Omit calcs that are resolved to `0px` from the serialized value - Allow CSV to be the 'Z' component in interpolated value. - Allow calcs with mixed percentages in the first two arguments. To achieve the third item above the concept of a "special" value parsing context has been added - this will also be useful for instance for different arguments of color functions having different contexts. Gains us 23 WPT tests	2025-08-08 09:45:00 +01:00
Callum Law	46153910ec	LibWeb: Update to_color to take ColorResolutionContext ... Using a generic context argument will allow us to resolve colors in places where we have all the required information but not in the form of a layout node as was expected previously.	2025-08-04 11:29:05 +01:00
Tim Ledbetter	ca9364983c	LibWeb/CSS: Support interpolating filter and backdrop-filter values	2025-07-30 23:29:07 +02:00
Tim Ledbetter	62e52163d6	LibWeb: Interpolate text-shadow values as a shadow list ... This is the same behavior as is currently used for `box-shadow`.	2025-07-30 10:51:50 +02:00
Tim Ledbetter	3ae48776fd	LibWeb: Round integral values to the nearest integer when interpolating ... Previously, color components were being incorrectly rounded when interpolating.	2025-07-30 10:51:50 +02:00
Arran Ireland	423e944a92	LibGfx+LibWeb: Upgrade to multi-arg subscript operator in Matrix ... See the following for more details: https://en.cppreference.com/w/cpp/language/operators.html#Array_subscript_operator	2025-07-28 09:15:23 +02:00
ayeteadoe	77d9508618	LibWeb/CSS: Fix implicit narrowing cast in interpolate_rotate ... The changes introduced in 484a09d6a2 broke the Windows LibWeb build, so this fixes that	2025-07-22 13:21:17 -06:00
Tim Ledbetter	484a09d6a2	LibWeb: Support interpolating rotate values	2025-07-22 11:09:45 +01:00
