LibWeb: Add comments and missing items of various IDL files 2023-10-25 17:27:19 +02:00			`// https://drafts.csswg.org/css-animations-1/#interface-csskeyframerule-idl`
LibWeb: Switch IDL from UseNewAKString to UseDeprecatedAKString NewAKString is effectively the default for any new IDL interface, so let's mark this as the default behavior. It also makes it much easier to figure out whatever interfaces are still left to port over to new AK String. 2023-09-03 02:00:01 +12:00			`[Exposed=Window]`
LibWeb: Add preliminary support for CSS animations This partially implements CSS-Animations-1 (though there are references to CSS-Animations-2). Current limitations: - Multi-selector keyframes are not supported. - Most animation properties are ignored. - Timing functions are not applied. - Non-absolute values are not interpolated unless the target is also of the same non-absolute type (e.g. 10% -> 25%, but not 10% -> 20px). - The JavaScript interface is left as an exercise for the next poor soul looking at this code. With those said, this commit implements: - Interpolation for most common types - Proper keyframe resolution (including the synthetic from-keyframe containing the initial state) - Properly driven animations, and proper style invalidation Co-Authored-By: Andreas Kling <kling@serenityos.org> 2023-05-26 23:30:54 +03:30			`interface CSSKeyframeRule : CSSRule {`

LibWeb/CSS: Merge style declaration subclasses into CSSStyleProperties We previously had PropertyOwningCSSStyleDeclaration and ResolvedCSSStyleDeclaration, representing the current style properties and resolved style respectively. Both of these were the CSSStyleDeclaration type in the CSSOM. (We also had ElementInlineCSSStyleDeclaration but I removed that in a previous commit.) In the meantime, the spec has changed so that these should now be a new CSSStyleProperties type in the CSSOM. Also, we need to subclass CSSStyleDeclaration for things like CSSFontFaceRule's list of descriptors, which means it wouldn't hold style properties. So, this commit does the fairly messy work of combining these two types into a new CSSStyleProperties class. A lot of what previously was done as separate methods in the two classes, now follows the spec steps of "if the readonly flag is set, do X" instead, which is hopefully easier to follow too. There is still some functionality in CSSStyleDeclaration that belongs in CSSStyleProperties, but I'll do that next. To avoid a huge diff for "CSSStyleDeclaration-all-supported-properties-and-default-values.txt" both here and in the following commit, we don't apply the (currently empty) CSSStyleProperties prototype yet. 2025-03-17 17:50:49 +00:00			`[SameObject, PutForwards=cssText] readonly attribute CSSStyleProperties style;`
