* Add support for table fixups (#30868)Martin Robinson2023-12-221-10/+10
| | | | | | | | | | | | | | | | This adds support for fixing up tables so that internal table elements that are not properly parented in the DOM have the correct box tree structure according to the CSS Table specification [1]. Note that this only comes into play when building the DOM via script, as HTML 5 has its own table fixups that mean that the box tree construction fixups here are not necessary. There are no tests for this change. In general, it's hard to write tests against the shape of the box tree, because it depends on the DOM. We plan to test this via WPT tests once layout is complete. 1. https://drafts.csswg.org/css-tables/#table-internal-element Co-authored-by: Oriol Brufau <obrufau@igalia.com>

* Anonymous boxes that wrap inlines should not inherit overflow (#30579)Martin Robinson2023-10-191-51/+60
| | | | | | | | | | | | | | In legacy layout, anonymous text wrappers were inheriting the `overflow` and `text-overflow` properties. This results in the creation of extra clipping for these anonymous wrappers which could clip away floats. We will likely implement `text-overflow` differently in non-legacy layout. This change marks all legacy layout pseudo elements as "legacy" and also adds a new pseudo element for non-legacy layout that does not inherit `overflow`. Fixes #30562.

* Add animation and transition support for pseudo-elementsMartin Robinson2020-06-161-1/+1
| | | | | | | | | | This change extends the DocumentAnimationSet to hold animations for pseudo-elements. Since pseudo-elements in Servo are not in the DOM like in Gecko, they need to be handled a bit carefully in stylo. When a pseudo-element has an animation, recascade the style. Finally, this change passes the pseudo-element string properly to animation events. Fixes: #10316

* style: Finer grained invalidation for attribute changes.Emilio Cobos Álvarez2020-06-041-6/+0
| | | | | | | | | | | | | | | | | | | | | | | This should help out quite a bit with uBO, which has lots of very general attribute selectors. We invalidate per attribute name rather than using a SelectorMap, which prevents matching for attribute selectors that can't have changed. The idea is that this should be generally cheaper, though there are cases where this would be a slight pesimization. For example, if there's an attribute selector like: my-specific-element[my-attribute] { /* ... */ } And you change `my-attribute` in an element that isn't a `my-specific-element`, before that the SelectorMap would've prevented us from selector-matching completely. Now we'd still run selector-matching for that (though the matching would be pretty cheap). However I think this should speed up things generally, let's see what the perf tests think before landing this though. Differential Revision: https://phabricator.services.mozilla.com/D76825

* style: Implement parsing / selector-matching for :is() and :where().Emilio Cobos Álvarez2020-04-181-12/+9
| | | | | | | | | | | | | | This implements the easy / straight-forward parts of the :where / :is selectors. The biggest missing piece is to handle properly invalidation when there are combinators present inside the :where. That's the hard part of this, actually. But this is probably worth landing in the interim. This fixes some of the visitors that were easy to fix. Differential Revision: https://phabricator.services.mozilla.com/D70788

* style: Correctly style dark scrollbars in tree components.Cameron McCormack2019-12-161-0/+5
| | | | | | | | | | | | | | | | We need to ensure the rules that override all properties for scrollbar part elements only apply to those that are NAC (and so will be eligible for NAC style sharing). We have some uses of non-NAC <scrollbar> elements that should continue to inherit properties from their parents. To avoid any changes in rule matching order that come with changing specificity, we add a new :-moz-native-anonymous-no-specificity pseudo-class. While we're here, we note :-moz-native-anonymous-no-specificity (and the regular :-moz-native-anonymous pseudo-class) as not needing style sharing cache revalidation, as we never share NAC styles.

| | | | | | | | | | | | This patch invalidates the style for `::selection`, which will restore the behavior before the regression. However, it's still not quite correct, because repaint is not triggered. Given that `::selection` requires some major change to implement https://github.com/w3c/csswg-drafts/issues/2474, we can address this problem later.

| | | | | | | | | I plan to change servo to use all: inherit on its UA sheet. I hope the patch below should make it good enough performance-wise. And also, it's probably broken so I don't think it's worth supporting it specially. Differential Revision: https://phabricator.services.mozilla.com/D8686
* style: Stop using PseudoElement::inherits_all.Emilio Cobos Álvarez2018-10-151-35/+3
| | | | | | | | | This was done that way just because Servo didn't support the `all` property at the time. We should do it this way and optimize it if it's slow. Though I suspect that most of stuff doesn't actually need to be inherited, my patch at bug 1498943 should make it much faster than what it would otherwise be.

* style: Implement the non-functional :host selector.Emilio Cobos Álvarez2018-04-091-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kinda tricky because :host only matches rules on the shadow root where the rules come from. So we need to be careful during invalidation and style sharing. I didn't use the non_ts_pseudo_class_list bits because as soon as we implement the :host(..) bits we're going to need to special-case it anyway. The general schema is the following: * Rightmost featureless :host selectors are handled inserting them in the host_rules hashmap. Note that we only insert featureless stuff there. We could insert all of them and just filter during matching, but that's slightly annoying. * The other selectors, like non-featureless :host or what not, are added to the normal cascade data. This is harmless, since the shadow host rules are never matched against the host, so we know they'll just never match, and avoids adding more special-cases. * Featureless :host selectors to the left of a combinator are handled during matching, in the special-case of next_element_for_combinator in selectors. This prevents this from being more invasive, and keeps the usual fast path slim, but it's a bit hard to match the spec and the implementation. We could keep a copy of the SelectorIter instead in the matching context to make the handling of featureless-ness explicit in match_non_ts_pseudo_class, but we'd still need the special-case anyway, so I'm not fond of it. * We take advantage of one thing that makes this sound. As you may have noticed, if you had `root` element which is a ShadowRoot, and you matched something like `div:host` against it, using a MatchingContext with current_host == root, we'd incorrectly report a match. But this is impossible due to the following constraints: * Shadow root rules aren't matched against the host during styling (except these featureless selectors). * DOM APIs' current_host needs to be the _containing_ host, not the element itself if you're a Shadow host.
