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
Tim Ledbetter	cf33dec6d6	LibWeb: Extract SLERP algorithm into its own method ... No functional changes.	2025-07-22 11:09:45 +01:00
Callum Law	6a9c8d7767	LibWeb: Don't resolve colors with unresolved components ... `CSSColorValue`s which have unresolved `calc` components should be able to be resolved. Previously we would always resolve them but with incorrect values. This is useful as we will now be able to now whether we should serialize colors in their normalized form or not. Slight regression in that we now serialize (RGB, HSL and HWB) colors with components that rely on compute-time information as an empty string, but that will be fixed in the next commit.	2025-07-16 13:05:33 +01:00
Gingeh	1b7323fc2d	LibWeb: Interpolate legacy colors in sRGB	2025-07-04 15:28:08 +01:00
Callum Law	9ab7c5d08d	LibWeb: Support relative lengths in calc color values ... Gains us ~40 WPT tests.	2025-07-04 13:18:55 +01:00
Callum Law	62d138ebf7	LibWeb: Allow passing a resolution context to CSSStyleValue::to_color ... This will be used for resolving any calculated style values within the various `CSSColorValue` sub-classes. No functionality changes.	2025-07-04 13:18:55 +01:00
Tim Ledbetter	b46378085d	LibWeb: Absolutize keyframe values before interpolating	2025-06-24 12:36:47 +01:00
Sam Atkins	1435480d76	LibWeb/CSS: Add fixme for sRGB color interpolation ... Corresponds to a0a9886063	2025-06-17 12:38:27 +01:00
Tim Ledbetter	a3f6e71e33	LibWeb/CSS: Disallow third argument in 2D scale functions	2025-06-15 15:59:02 +02:00
Tim Ledbetter	17f14a277b	LibWeb: Don't crash when interpolating single-value repeatable lists ... Previously, when interpolating a repeatable list from a list with multiple values to a single value, we would crash.	2025-06-02 11:33:01 +01:00
Tim Ledbetter	b16f34767e	LibWeb: Ensure discrete interpolated properties are non-transitionable ... If a property is uses discrete interpolation and TransitionBehavior is not set to `AllowDiscrete` that property should be non-transitionable. This is now true for properties whose animation type is not discrete, but the animation type falls back to discrete.	2025-05-27 13:33:29 +02:00
Tim Ledbetter	09f4d90594	LibWeb: Clamp interpolated values to the range of their numeric type ... This fixes a UBSAN warning that we previously hit when interpolating color values.	2025-05-19 11:31:47 +01:00
Sam Atkins	eec4365542	LibWeb/CSS: Extract SerializationMode into its own header ... Prep for using this to serialize dimension types, and perhaps other things in the future.	2025-05-17 07:53:24 +01:00
Sam Atkins	4edafb35cd	LibWeb/CSS: Use PendingSubstitutionValue for unresolved shorthands ... Previously, we would just assign the UnresolvedStyleValue to each longhand, which was completely wrong but happened to work if it was a ShorthandStyleValue (because that's basically a list of "set property X to Y", and doesn't care which property it's the value of). For example, the included `var-in-margin-shorthand.html` test would: 1. Set `margin-top` to `var(--a) 10px` 2. Resolve it to `margin-top: 5px 10px` 3. Reject that as invalid What now happens is: 1. Set `margin-top` to a PendingSubstitutionValue 2. Resolve `margin` to `5px 10px` 3. Expand that out into its longhands 4. `margin-top` is `5px` 🎉 In order to support this, `for_each_property_expanding_shorthands()` now runs the callback for the shorthand too if it's an unresolved or pending-substitution value. This is so that we can store those in the CascadedProperties until they can be resolved - otherwise, by the time we want to resolve them, we don't have them any more. `cascade_declarations()` has an unfortunate hack: it tracks, for each declaration, which properties have already been given values, so that it can avoid overwriting an actual value with a pending one. This is necessary because of the unfortunate way that CSSStyleProperties holds expanded longhands, and not just the original declarations. The spec disagrees with itself about this, but we do need to do that expansion for `element.style` to work correctly. This HashTable is unfortunate but it does solve the problem until a better solution can be found.	2025-05-14 11:46:47 +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

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

Andrew Kaster	d1f6f5649e	LibWeb: Make storage of CSS::CalculationNodes const-correct ... Now we consistently use `RefPtr<CalculationNode const>` for all CalculationNodes.	2025-04-16 10:41:44 -06:00
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
Tim Ledbetter	f07a3fe6da	LibWeb: Use discrete interpolation for degenerate ratios ... Degenerate ratios cannot be interpolated.	2025-04-11 11:38:05 +01:00

InvalidUsernameException	f7276bfab3	LibWeb: Reduced number of recompiled files for CSS property headers ... This reduces the number of `.cpp` files that need to be recompiled when one of the below header files changes as follows: CSS/ComputedProperties.h: 1113 -> 49 CSS/ComputedValues.h: 1120 -> 209	2025-02-23 10:14:39 -05:00
Sam Atkins	c3d61020e7	LibWeb/CSS: Make CalculationNodes ref-counted ... Calc simplification (which I'm working towards) involves repeatedly deriving a new calculation tree from an existing one, and in many cases, either the whole result or a portion of it will be identical to that of the original. Using RefPtr lets us avoid making unnecessary copies. As a bonus it will also make it easier to return either `this` or a new node. In future we could also cache commonly-used nodes, similar to how we do so for 1px and 0px LengthStyleValues and various keywords.	2025-01-30 19:31:54 +01:00
Sam Atkins	ac15e626dd	LibWeb/CSS: Merge ScaleStyleValue into TransformationStyleValue ... The only ways this varies from the `scale()` function is with parsing and serialization. Parsing stays separate, and serialization is done by telling `TransformationStyleValue` which property it is, and overriding its normal `to_string()` code for properties other than `transform`.	2025-01-17 10:12:39 +01:00
Sam Atkins	18e0ff6537	LibWeb/CSS: Properly classify calculations inside transform functions ... Assuming all calculations produce `<length-percentage>` is a very bad assumption, and was causing crashes on https://ai.cloudflare.com/	2025-01-15 14:29:08 +00:00
Sam Atkins	4efdb76857	LibWeb/CSS: Give calc() a CalculationContext for resolving percentages ... This is passed in at construction, meaning we will be able to refer to it later, when we're no longer inside the Parser.	2025-01-13 10:59:16 +00:00
Sam Atkins	69a0f28d04	Revert "LibWeb/CSS: Rename CalculatedStyleValue -> CSSMathValue" ... This reverts commit 76daba3069. We're going to need separate types for the JS-exposed style values, so it doesn't make sense for us to match their names with our internal types.	2024-12-21 18:14:28 +01:00
Sam Atkins	ee9db99961	LibWeb: Remove unused Realm arg from StyleComputer::get_inherit_value() ... We no longer need this now that property_initial_value() doesn't take a Realm.	2024-12-05 19:59:57 +01:00
Sam Atkins	2c3c821305	LibWeb: Remove Realm parameter from property_initial_value() ... We don't need the Realm to parse a style value. Fixes #2720	2024-12-05 19:59:57 +01:00
Glenn Skrzypczak	0d15cc4672	LibWeb/Animation: Fall back to discrete animation in more cases ... Use discrete animation when the number of components or the types of corresponding components do not match. This commit does not cover all cases, but adds FIXME comments in the appropriate places.	2024-11-25 18:10:24 +01:00
