InvalidUsernameException	029bcf13fd	Libweb: Invalidate layout for the value-attribute of li-elements	2025-05-11 01:14:31 +02:00
InvalidUsernameException	370098514a	LibWeb: Invalidate layout for ol-attributes that affect it	2025-05-11 01:14:31 +02:00
Andreas Kling	263b125782	LibWeb: Let HTMLTokenizer walk over code points instead of UTF-8 ... Instead of using UTF-8 iterators to traverse the HTMLTokenizer input stream one code point at a time, we now do a one-shot conversion up front from the input encoding to a Vector<u32> of Unicode code points. This simplifies the tokenizer logic somewhat, and ends up being faster as well, so win-win. 1.02x speedup on Speedometer 2.1	2025-05-11 01:13:20 +02:00
Andrew Kaster	accb77fda9	LibWeb: Add missing WebIDL/Types include to MediaCapabilities.h ... This causes a build failure when building a clang module for LibWeb.	2025-05-09 23:14:27 -06:00
Jelle Raaijmakers	70b52e0994	LibWeb: Use efficient background repeat path for either direction ... We're able to efficiently draw repeated bitmaps through Skia, but for backgrounds we only did so if the background was `repeat-x` _and_ `repeat-y`, and not if just one was set. This meant that for backgrounds that were only repeating in one direction, we were taking the slow path. Turns out that this slow path also produced graphical artifacts when zooming in and out, so let's not do that :^)	2025-05-09 21:37:48 +02:00
Timothy Flynn	30e8f3f1ad	LibWeb: Update the <details> layout tree when it is opened/closed ... Otherwise, the arrow painted next to the <details> element does not update. Using a screenshot test here because apparently the direction of the arrow has no effect on the layout or paint trees.	2025-05-09 21:37:14 +02:00
Andreas Kling	f61df9d34c	LibWeb: Don't throw away UA shadow trees willy-nilly ... We were unnecessarily discarding the shadow trees of various elements when they were removed or detached from the DOM. This especially caused a *lot* of churn when creating input elements via setting .innerHTML on something. We ended up building each input element's shadow tree 3 times instead of 1. The original issue that we were trying to solve by discarding shadow trees appears to have been solved elsewhere, and nothing else seems to break by just allowing them to remain in place. 1.05x speedup on Speedometer's TodoMVC-jQuery.	2025-05-09 12:49:04 -04:00
Jelle Raaijmakers	123abe0e79	LibWeb: Overlap float space and left margins for all shared ancestors ... We would only correct for the left margin of the containing block of the child box that we are laying out, but we actually need to correct for all left margins up until the containing block that contains both the float and the child box. Fixes #4639.	2025-05-09 14:13:02 +02:00
Sam Atkins	90d466e7e9	LibWeb: Add dumping code for keyframe/keyframes rules	2025-05-08 16:21:32 +01:00
Sam Atkins	fbdef98307	LibWeb: Dump CSSDescriptors in a generic way ... This replaces the need for bespoke (and verbose) dumping for each at-rule that has descriptors.	2025-05-08 16:21:32 +01:00
Sam Atkins	f0ce4f43a6	LibWeb: Make unknown webkit pseudo-elements safe to dump ... This fixes a couple of crashes when dumping the style sheets on ladybird.org	2025-05-08 16:21:32 +01:00
Sam Atkins	0925a32558	LibWeb/CSS: Extract a CSSDescriptors base class ... This holds the boilerplate that's needed by any CSSStyleDeclaration subclass that holds Descriptors. CSSFontFaceDescriptors now only has to worry about initialization and its own exposed properties.	2025-05-08 16:21:32 +01:00
Kenneth Myhra	6941b63890	LibWeb: Add {,de}serialization steps for ImageData	2025-05-09 02:12:01 +12:00

Jelle Raaijmakers	f996fb9d80	LibWeb: Translate special WebDriver keys for backspace, tab and return ... These private code points are used extensively by WebDriver clients, such as the WPT suite.	2025-05-08 07:06:02 -04:00
Timothy Flynn	c846616d51	LibWeb: Adjust positions by the scroll offset for scrollbar hit testing ... This ensures we scroll to the correct position when dragging a scrollbar or clicking its gutter.	2025-05-08 10:40:58 +01:00
Timothy Flynn	22532c769c	LibWeb: Be less lenient in scrollbar hit testing ... A scrollbar contains a mouse position only if its gutter rect contains that position. We were incorrectly deciding a position was contained if it fell to the right of a vertical scrollbar, or below a horizontal scrollbar.	2025-05-08 10:40:58 +01:00
Sam Atkins	a8529629e2	LibWeb/HTML: Update "is script closable" to current spec ... Corresponds to d7fc63a84a and 7a48703e77	2025-05-08 10:39:34 +01:00
Ali Mohammad Pur	638a354b29	LibWeb/WebAssembly: Throw appropriate errors as defined by the spec	2025-05-08 03:35:11 -06:00
Ali Mohammad Pur	333ba93d49	LibWeb/WebAssembly: Define the hacky 'native' errors given in the spec ... These cannot be implemented "correctly" as the set of native errors as defined by ecma262 is closed, but we can get pretty close.	2025-05-08 03:35:11 -06:00

Jelle Raaijmakers	d424dc1b32	LibWeb: Assign new wrapped node list to container for insertParagraph ... Forgot to implement this part of the spec.	2025-05-07 16:11:31 +02:00
Jelle Raaijmakers	c56f7d9cde	LibWeb: Invalidate sibling style for :only-child and :*-of-type ... After f7a3f785a8, sibling nodes' styles were no longer invalidated after a node was removed. This reuses the flag for `:first-child` and `:last-child` to indicate that a node's style might be affected by any structural change in its siblings. Fixes #4631. Resolves the `:only-child` ACID3 failure as documented in #1231.	2025-05-07 14:55:12 +03:00

Timothy Flynn	0da7441b9b	LibWeb: Set the initiator type for script-initiated CSS requests ... Similar to other ad-hoc behavior in this method, we need to handle requests which are not associated with a style sheet. For example: <script> const element = document.createElement('div'); element.style['background'] = 'url(https://foo.com/img.png)'; document.body.appendChild(element); </script> Will not be associated with a style sheet. This is needed to ensure we fire a PerformanceResourceTiming event for this resource load. This is not currently testable in CI, as this event is also gated by HTTP/S requests.	2025-05-06 17:37:34 +01:00
Timothy Flynn	4fc8443757	LibWeb: Translate scrollbar gutters by the cumulative scroll offset ... This `translate_by` function is invoked with the cumulative scroll offset during display list execution. Applying the offset to the gutter was missed in 66e422b4f1.	2025-05-06 16:38:23 +03:00

Andreas Kling	183c847c80	LibJS: Cache PutById to setters in the prototype chain ... This is *extremely* common on the web, but barely shows up at all in JavaScript benchmarks. A typical example is setting Element.innerHTML on a HTMLDivElement. HTMLDivElement doesn't have innerHTML, so it has to travel up the prototype chain until it finds it. Before this change, we didn't cache this at all, so we had to travel the prototype chain every time a setter like this was used. We now use the same mechanism we already had for GetBydId and cache PutById setter accesses in the prototype chain as well. 1.74x speedup on MicroBench/setter-in-prototype-chain.js	2025-05-05 15:21:43 +02:00
Jelle Raaijmakers	71665fa504	LibWeb: Scale font size by 1.15 for line-height: normal ... Browsers such as Chrome and Firefox apply an arbitrary scale to the current font size if `normal` is used for `line-height`. Firefox uses 1.2 while Chrome uses 1.15. Let's go with the latter for now, it's relatively easy to change if we ever want to go back on that decision. This also requires updating the expectations for a lot of layout tests. The upside of this is that it's a bit easier to compare our layout results to other browsers', especially Chrome.	2025-05-05 13:15:56 +02:00
Psychpsyo	7c36a82129	LibWeb: Improve parsing for the CSS contain property ... This makes us actually respect the grammar and nets us a couple extra WPT passes in the parsing section.	2025-05-04 22:24:26 +01:00
Timothy Flynn	1c075d6039	LibWeb: Remove Web::Infra ASCII case conversion methods ... We have more optimized versions of these methods in AK.	2025-05-04 15:59:17 +02:00
