Callum Law	778da0175e	LibWeb: Clamp and censor top-level calc results ... We now clamp the values returned from calc into the allowed range (where we know it) and censor any `NaN`s to `0` both when we resolve and when we serialize. Gains us 76 WPT passes.	2025-08-11 17:10:04 +01:00
Callum Law	c49afd7b28	LibWeb: Absolutize LengthPercentage members of BorderRadiusStyleValues	2025-08-06 17:44:12 +01:00
Callum Law	70cb8d23fb	Tests: Import/create tests related to absolutization of StyleValues ... Done in a separate commit to show progress	2025-08-06 17:44:12 +01:00
Callum Law	ba4a57b34d	LibWeb: Absolutize StyleValueList in StyleComputer::absolutize_values	2025-08-06 17:44:12 +01:00
Tim Ledbetter	e36df5ea0a	LibWeb: Serialize background-size auto correctly ... When `background-size` is `auto` in both axes, the `auto` value is no longer repeated.	2025-08-02 08:51:23 +02:00
Tim Ledbetter	4c91b42dd2	LibWeb: Use shortest serialization for repeated style list values	2025-08-01 15:18:17 +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
Andreas Kling	92221f0c57	LibWeb: Apply all animations and transitions before invalidating style ... This fixes an issue where only the last KeyframeEffect applied to an element would actually have an effect on the computed properties. It was particularly noticeable when animating a shorthand property like border-width, since only one of the border edges would have its width actually animate. By deferring the invalidation until all animations have been processed, we also reduce the amount of work that gets done on pages with many animations/transitions per element. Discord is very fond of this for example.	2025-07-19 11:08:46 -04:00
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
Tim Ledbetter	923deb0c01	LibWeb: Parse border-image shorthand property	2025-07-03 10:19:44 +01:00
Tim Ledbetter	c0390f759c	LibWeb: Parse the border-image-repeat property	2025-07-03 10:19:44 +01:00
Tim Ledbetter	98e63e3dd5	LibWeb: Parse the border-image-outset property	2025-07-03 10:19:44 +01:00
Tim Ledbetter	245905b833	LibWeb: Parse the border-image-slice property	2025-07-03 10:19:44 +01:00
Tim Ledbetter	70c2621634	LibWeb: Parse the border-image-source property	2025-07-03 10:19:44 +01:00
Gingeh	e96338dd63	LibWeb: Don't play initially-paused animations	2025-06-18 17:17:29 +02:00
Tim Ledbetter	d89a67ffee	LibWeb: Don't serialize omitted box-shadow and text-shadow values	2025-06-15 16:05:12 +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	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	c4d298674b	Tests: Re-enable interpolation tests ... These run significantly faster than they did when they did when they were disabled.	2025-05-19 11:31:47 +01:00
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
Tim Ledbetter	7d7bab7cac	LibWeb: Ensure resolved border-width values are non-negative	2025-05-19 09:55:09 +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
Tim Ledbetter	64577ad704	LibWeb: Allow multiple values for the transition-duration property	2025-04-23 21:02:59 +01:00
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	3186adeaa1	LibWeb/CSS: Don't serialize longhands which match their initial values ... Shorthand subproperties that match their initial values are now excluded from serialization, by default. Properties where this behavior is not desired, like `gap`, are special-cased.	2025-04-07 11:38:56 +01:00
Tim Ledbetter	8738987e44	LibWeb: Return absolutized computed value for border width properties	2025-04-04 23:45:06 +02:00
Tim Ledbetter	f6a8e5aa68	LibWeb: Use correct canonical serialization for BorderRadiusStyleValue	2025-03-18 21:55:06 +01:00
Tim Ledbetter	85728b297f	LibWeb: Ensure the shortest serialization is used for border-radius ... This implementation also fixes an issue where the individual components of the `border-radius` shorthand were always assumed to be of type `BorderRadiusStyleValue`, which could lead to a crash when CSS-wide keywords were used.	2025-03-18 21:55:06 +01:00
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	764b80a1cc	LibWeb/CSS: Reject radial-gradient functions with negative size	2025-03-14 15:07:57 +00:00

Andreas Kling	87dd8714c5	Tests: Import WPT tests from css/css-backgrounds/animation ... These give us some basic coverage of backgrounds, borders and animation mechanisms.	2024-11-07 22:50:33 +01:00
