Aliaksandr Kalenik	af602b2555	LibWeb: Align CSS Grid properties parsing with the specification ... Reimplements `grid`, `grid-template`, `grid-template-rows`, and `grid-template-columns` in a way that uses a separate function for each grammar rule defined in the specification. This change results in many additional passing tests from the already imported WPT suite. Most of the remaining test failures are related to incorrect serialization of grid properties.	2025-06-21 22:07:08 +02:00

Jelle Raaijmakers	30efcd0d00	LibWeb: Prevent time-traveling leading inline metrics ... In `InlineLevelIterator`, whenever we call `skip_to_next()` and enter a node with box model metrics, we could potentially accumulate leading and trailing metrics. This lead to a weird situation where an element with `display: inline-block` could adopt the leading metrics of an inline element that follows it, since we perform the call to `add_extra_box_model_metrics_to_item()` too late. Move `skip_to_next()` down so it no longer interferes with the `Item` we're creating. The test expectation for `atomic-inline-with-percentage-vertical-align.html` is updated, although neither the old nor new results are 100% accurate since either box jumps one pixel to the right.	2025-06-20 19:59:32 +02:00
Tim Ledbetter	16dbb44de2	LibWeb: Update DOMImplementation.createDocumentType() name validation ... This now follows the latest specification steps.	2025-06-19 07:55:47 -04:00
Sam Atkins	c1d4323cf7	LibWeb: Support counter-* properties on pseudo-elements ... There are multiple things happening here which are interconnected: - We now use AbstractElement to refer to the source of a counter, which means we also need to pass that around to compute `content`. - Give AbstractElement new helper methods that are needed by CountersSet, so it doesn't have to care whether it's dealing with a true Element or PseudoElement. - The CountersSet algorithms now walk the layout tree instead of DOM tree, so TreeBuilder needs to wait until the layout node exists before it resolves counters for it. - Resolve counters when creating a pseudo-element's layout node. We awkwardly compute the `content` value up to twice: Once to figure out what kind of node we need to make, and then if it's a string, we do so again after counters are resolved so we can get the true value of any `counter()` functions. This will need adjusting in the future but it works for now.	2025-06-19 12:35:31 +01:00

Manuel Zahariev	51b4b4a270	LibWeb: Tests for recalculating ordinals after list manipulation ... FIXME: Rendering modifications to a list is sometimes not pixel-perfect vs. reference (likely a bug). After this is fixed, screenshot tests from this commit will likely fail + can be moved to ref tests.	2025-06-16 12:44:58 +01:00
Manuel Zahariev	20546725be	LibWeb: Tests for rendering lists and their ordinals ...

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
