Sam Atkins	a57595faf5	LibWeb: Make [resolve,inherit]_counters() take AbstractElement ... This is one of those cases where the spec says "element" and means "element or pseudo-element". The easiest way to handle both is to make these be free functions that take an AbstractElement, and then give AbstractElement some helper methods so that the caller doesn't have to care which it's dealing with. There are some FIXMEs here because PseudoElement doesn't have a CountersSet yet, and because the CountersSet currently uses a UniqueNodeID to identify counter sources, which doesn't support pseudo-elements.	2025-06-19 12:35:31 +01:00
Sam Atkins	ce380a59c7	LibWeb/DOM: Rename ElementReference to AbstractElement ... This isn't some kind of identifier, it's a handle on an actual Element or PseudoElement.	2025-06-19 12:35:31 +01:00

Aliaksandr Kalenik	6169e91994	LibWeb: Delete redundant GridFitContent class from track representation ... GridSize already supports the FitContent type, so there is no need to additionally wrap it in a GridFitContent class.	2025-06-18 15:51:10 +01:00

Sam Atkins	7fe854c131	LibWeb/CSS: Link CalculationContext to new spec definition ... Corresponds to ad244f3413 There's nothing that we need to do differently I think, but it's nice to have a clear spec definition to refer to. :^)	2025-06-17 12:38:27 +01:00

Tim Ledbetter	30cdacc05a	LibWeb: Add flow relative values for the clear property ... Currently `inline-start` and `inline-end` are always treated as `left` and `right` respectively.	2025-06-17 09:26:26 +02:00
Tim Ledbetter	28b24b72bc	LibWeb: Don't resolve flow-relative values for float too early ... This allows `getComputedStyle()` to return the correct value if `float` is set to `inline-start` or `inline-end`	2025-06-17 09:26:26 +02:00
Tim Ledbetter	6c6219db05	LibWeb: Use shorthand keywords for contain used value where possible ... The used value of `contain` is now set to `strict` or `content` when the relevant set of containment keywords are specified.	2025-06-17 08:17:33 +01:00
Tim Ledbetter	96d8bed35b	LibWeb/CSS: Serialize contain values in canonical order	2025-06-17 08:17:33 +01:00
Callum Law	12c9da2d3f	LibWeb: Serialize grid/grid-template as "none" when applicable ... This exposes a bunch of false-positives in the grid-{shorthand,template}-invalid.html WPT tests, but gains us some new passes as well.	2025-06-16 12:37:40 +01:00
Callum Law	7d81823eb3	LibWeb: Handle CSS-wide keywords in style_property_for_sided_shorthand ... CSS-wide keywords should not be concatenated in the same way as other values unless they are all the same.	2025-06-16 12:37:40 +01:00
Callum Law	62da650992	LibWeb: Don't serialize longhands if we directly serialized shorthand ... The spec assumes that we only store values against expanded longhands, there are however limited circumstances where we store against shorthands directly in addition to the expanded longhands. For example if the value of the shorthand is unresolved we store an UnresolvedStyleValue against the shorthand directly and a PendingSubstitutionStyleValue against each of the longhands. This commit updates the logic so that in the case we serialize a shorthand directly we should also mark it's longhands as serialized to avoid serializing them separately. This also avoids the scenario where we tried to create and serialize a ShorthandStyleValue with PendingSubstitutionStyleValue longhands, so we can remove the check and related FIXME for that.	2025-06-16 12:37:40 +01:00
Callum Law	f8f4da3b90	LibWeb: Don't serialize shorthand with non-uniform CSS-wide keywords	2025-06-16 12:37:40 +01:00
Callum Law	3c6b8d5a2c	LibWeb: Propagate CSS-wide keyword to transition longhands ... Previously we would treat CSS-wide keywords as equivalent to "none"	2025-06-16 12:37:40 +01:00
Callum Law	335190e925	LibWeb: Handle nested shorthands in all-same-CSS-wide-keyword to_string ... Previously we only checked direct sub-properties, not accounting for the nested case.	2025-06-16 12:37:40 +01:00

Tim Ledbetter	68d3ddb1a7	LibWeb: Parse the transform-origin z-value	2025-06-15 16:01:54 +02:00
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

Aliaksandr Kalenik	8d83dce1d7	LibWeb: Use variant to represent CSS::ExplicitGridTrack ... No behavior change.	2025-06-13 19:57:00 +02:00
Jelle Raaijmakers	15c436b332	LibWeb: Implement basic focus indication for :focus-visible ... This causes links to no longer show an outline when clicked; only when using keyboard navigation with the tab key will the outline show up.	2025-06-13 17:39:11 +02:00
Callum Law	64d79d4c3f	LibWeb: Avoid overwriting resolved values in compute_keyframe_values ... When we have an unresolved value for a shorthand (e.g. `border-style: var(--border-style)`, `keyframe_values` will contain an `UnresolvedStyleValue` for the shorthand and `PendingSubstitutionStyleValue`s for each of it's longhands. When we come across the shorthand's `UnresolvedStyleValue` we will resolve the value and set all of the relevant longhands. If the longhand's `PendingSubstitutionStyleValue` was processed after (which isn't always the case as the iteration order depends on a HashMap) would overwrite the correctly resolved longhand. To avoid this we just skip any `PendingSubstitutionStyleValue`s we come across and rely on the resolution of the shorthand to set those properties. Resolves a crash @tcl3 was experiencing when adding a new "border-image-repeat" property.	2025-06-13 17:06:00 +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
Sam Atkins	00f76ccbf4	LibWeb/CSS: Add alternative src() syntax for URLs ... url() has some limitations because of allowing unquoted URLs as its contents. For example, it can't use `var()`. To get around this, there's an alternative `src()` function which behaves the same as `url()` except that it is parsed as a regular function, which makes `var()` and friends work properly. There's no WPT test for this as far as I can tell, so I added our own.	2025-06-11 16:26:23 +02:00
Andreas Kling	ea0bfda1b9	LibWeb: Cache the font in StyleComputer::initial_font() ... This function is bogus, but it's still getting called a lot during media query evaluation, so let's at least cache the font instead of recreating it every single time.	2025-06-11 16:25:42 +02:00
Callum Law	a9eecf76df	LibWeb: Dont compute style when CSSStyleProperties lacks owner node ... Some instances of CSSStyleProperties can lack an owner node, for instance the return value of a call to `window.getComputedStyle` where the specified pseudo-element is invalid. In this case we should treat the computed style as empty, as there is no node to compute the style for.	2025-06-09 12:28:41 +01:00
