Timothy Flynn	8600925713	LibWeb: Port HTMLElement innerText/outerText to UTF-16	2025-07-28 18:30:50 +02:00
Timothy Flynn	5c561c1a53	LibWeb: Port node text content to UTF-16	2025-07-28 18:30:50 +02:00
Timothy Flynn	27a4c1eaf6	LibWeb: Remove errant comment from HTMLElement::rendered_text_fragment ... This became untrue in a1a740bb3e.	2025-07-28 18:30:50 +02:00
Timothy Flynn	97548f48de	LibWeb: Port rendered text to UTF-16 ... This migrates TextNode::text_for_rendering() to Utf16String and deals with the fallout. As a consequence, this effectively reverts commit 3df83dade8. The layout test expecation file updates are because we now express text lengths and offsets in UTF-16 code units. The selection-over-multiple-code-units expectation file update actually represents a correctness fix. Our result now matches Firefox.	2025-07-25 18:16:22 +02:00
Timothy Flynn	8b6e3cb735	LibWeb+LibUnicode+WebContent: Port DOM:CharacterData to UTF-16 ... This replaces the underlying storage of CharacterData with Utf16String and deals with the fallout.	2025-07-24 19:00:20 +02:00
Sam Atkins	e74afec9c5	LibWeb: Capitalize "No Popover state" consistently ... Corresponds partly to 8035a256bf	2025-07-08 17:08:39 +01:00
Andreas Kling	b3d9e39bad	LibWeb: Avoid infinite loop in HTMLElement.scrollParent ... We were failing to actually climb up the containing block chain, causing this API to infinite loop for anything but the most trivial cases. By fixing the loop structure, we also make a bunch of the already imported WPT tests pass. :^)	2025-06-30 20:38:21 +01:00
Sam Atkins	423cdd447d	LibWeb+LibGfx: Apply editorial punctuation/whitespace/markup fixes ... Corresponds to d426109ea1 and fd08f81d06	2025-06-25 03:12:19 +12:00
Andreas Kling	63d862219e	LibWeb: Avoid expensive Vector::insert() in innerText & outerText ... When expanding "required line breaks", we now write directly into the final StringBuilder instead of doing a pass of Vector remove/insert operations first. This removes a hot profile item on https://serpapi.com/	2025-06-19 17:31:22 +02:00
Gingeh	5e1e0d4e18	LibWeb: Remove some popover AD-HOC comments ... Spec PR: https://github.com/whatwg/html/pull/11253	2025-06-18 08:51:22 +02:00
Sam Atkins	af9a227ca3	LibWeb/HTML: Implement HTMLElement.scrollParent ... Corresponds to d3effb701c What a "fixed position container" is isn't clear to me, and we don't seem to use that elsewhere, so I've left the steps using that as FIXMEs for now. There's no test coverage for this in WPT yet and I'm not confident enough in the specific behaviour to write one myself. So, waiting on https://github.com/web-platform-tests/wpt/issues/53214	2025-06-17 12:38:27 +01:00
Sam Atkins	5d5f16845c	LibWeb/HTML: Bring HTMLElement::offset_parent() up to date	2025-06-17 12:38:27 +01:00
Gingeh	fc35229dab	LibWeb: Implement the ToggleEvent.source attribute ... See: https://github.com/whatwg/html/pull/11186	2025-06-07 04:06:01 +01:00
Shannon Booth	937994cfaa	LibWeb: Make Environment's top level origin nullable ... This matches the definition in the spec, and is also a step towards removing the default constructor of URL::Origin.	2025-05-27 14:48:43 +12:00
Callum Law	279913a223	LibWeb: Implement the translate attribute	2025-05-23 14:34:06 +02:00
Gingeh	fbc56f74bd	LibWeb: Move popover invoker reset later ... See https://github.com/whatwg/html/pull/11304	2025-05-22 07:55:34 +01:00
Noah	85842c1739	LibWeb: Stub out several methods for ElementInternals ... This begins implementation on form-associated custom elements. This fixes a few WPT tests which I'm importing. Co-authored-by: Sam Atkins <sam@ladybird.org>	2025-05-21 15:28:10 +01:00
Shannon Booth	579730d861	LibWeb: Prefer using equals_ignoring_ascii_case ... Which has an optmization if both size of the string being passed through are FlyStrings, which actually ends up being the case in some places during selector matching comparing attribute names. Instead of maintaining more overloads of Infra::is_ascii_case_insensitive_match, switch everything over to equals_ignoring_ascii_case instead.	2025-05-21 13:45:02 +01:00
Gingeh	1f1884da54	LibWeb: Light dismiss popovers on click	2025-04-28 19:41:38 -06:00
Gingeh	7b8af4d84c	LibWeb: Remove a popover AD-HOC comment after spec update ... See https://github.com/whatwg/html/pull/11197	2025-04-23 10:13:29 +01:00
Andreas Kling	a6dfc74e93	LibWeb: Only set prototype once for object with IDL interface ... Before this change, we were going through the chain of base classes for each IDL interface object and having them set the prototype to their prototype. Instead of doing that, reorder things so that we set the right prototype immediately in Foo::initialize(), and then don't bother in all the base class overrides. This knocks off a ~1% profile item on Speedometer 3.	2025-04-20 18:43:11 +02:00
Shannon Booth	3e17b1c9ae	LibWeb: Make Node::parent_element return GC::Ptr ... This is useful for people like myself who run with debug mode to more reliably get stacktraces without spinning up a debugger.	2025-04-18 10:49:02 +02:00
Viktor Szépe	5cc371d54c	LibWeb: Fix typos - act II	2025-04-09 15:05:20 +01:00
Andreas Kling	53da8893ac	LibJS: Replace PropertyKey(char[]) with PropertyKey(FlyString) ... ...and deal with the fallout.	2025-03-24 22:27:17 +00:00
Andreas Kling	c333042e63	LibWeb: Add opt-in tracing of update_layout() calls with reason	2025-03-08 03:37:38 +01:00
InvalidUsernameException	f7276bfab3	LibWeb: Reduced number of recompiled files for CSS property headers ... This reduces the number of `.cpp` files that need to be recompiled when one of the below header files changes as follows: CSS/ComputedProperties.h: 1113 -> 49 CSS/ComputedValues.h: 1120 -> 209	2025-02-23 10:14:39 -05:00
Tim Ledbetter	a9ffc6359a	LibWeb: Set inertness of HTMLElement when inert attribute is changed	2025-02-21 12:41:57 +00:00
Gingeh	91e4fb248b	LibWeb: Hide unrelated popovers when showing popovers ... Also hides decendant popovers when hiding. Also hides unrelated popovers when showing dialogs.	2025-02-16 19:40:07 +00:00

Aliaksandr Kalenik	da579e11b0	LibWeb: Start implementing render-blocking mechanism from HTML spec ... This change implements enough spec steps to block rendering until execution of sync scripts inserted from HTML parser is complete.	2025-02-05 18:28:46 +01:00
Sam Atkins	1bd73184da	LibWeb/HTML: Update get_an_elements_noopener() to current spec ... Note that this preemptively includes this fix to step 3: https://github.com/whatwg/html/pull/10962	2025-01-31 17:27:03 +00:00
Sam Atkins	9254994687	LibWeb/HTML: Update get_an_elements_target() to current spec	2025-01-31 17:27:03 +00:00

Gingeh	b056e27afd	LibWeb: Hide visible popover when type is changed	2025-01-30 15:46:52 -07:00
Gingeh	e670caeb0c	LibWeb: Ignore DOM state when hiding removed popovers ... Using https://github.com/whatwg/html/pull/9457 (with some changes made to catch up with the current spec) to fix a spec bug and a crash when removing a visible popover.	2025-01-30 15:46:52 -07:00
Luke Warlow	391a08bf17	LibWeb: Update spec comments for dialog, popover and close watcher	2025-01-25 03:40:08 +00:00
Luke Warlow	f5860a3b7d	LibWeb: Implement hidden="until-found" IDL support ... Follow-ups will implement the actual behaviour.	2025-01-24 09:08:37 +01:00
Andreas Kling	7269fc3e52	LibWeb: Pass old parent's root to Node::removed_from() ... This will allow nodes to access the root they've just been removed from.	2025-01-23 21:38:31 +01:00
Jelle Raaijmakers	336684bc5c	LibWeb: Support inserting non-inline elements into inline elements ... Our layout tree requires that all containers either have inline or non-inline children. In order to support the layout of non-inline elements inside inline elements, we need to do a bit of tree restructuring. It effectively simulates temporarily closing all inline nodes, appending the block element, and resumes appending to the last open inline node. The acid1.txt expectation needed to be updated to reflect the fact that we now hoist its <p> elements out of the inline <form> they were in. Visually, the before and after situations for acid1.html are identical.	2025-01-23 09:33:10 +01:00
Timothy Flynn	85b424464a	AK+Everywhere: Rename verify_cast to as ... Follow-up to fc20e61e72.	2025-01-21 11:34:06 -05:00
Tim Ledbetter	a467005855	LibWeb: Make node cloning methods const	2025-01-11 23:10:09 +01:00
sideshowbarker	56c7857053	LibWeb: Return true for is_focusable() elements with non-null tabindex ... This change implements the requirements stated in the HTML spec at https://html.spec.whatwg.org/multipage/interaction.html#tabindex-value that UAs must allow HTML elements with non-null tabindex values to be considered as focusable areas.	2025-01-09 14:08:23 +00:00
Shannon Booth	44bb2b7e32	LibWeb/HTML: Use paintable box for 'associated CSS layout box' check ... This is consistent with other functions such as HTMLElement::offset_width and fixes a crash for the included test. Returning an offset of zero is not correct for this case, but this is still an improvement to not crash.	2025-01-02 11:28:37 +01:00
Shannon Booth	372f2dd7a1	LibWeb/HTML: Remove uneeded handling for non-box paintable HTMLElements ... All inline nodes are now PaintableBoxes, so we do not need to handle the non box case any more :^)	2025-01-02 11:28:37 +01:00
sideshowbarker	5ba847b1c4	LibWeb: Minor code cleanup: Replace some first_is_one_of with is_one_of	2024-12-27 17:16:34 -08:00
Andreas Kling	c1cad8fa0e	LibWeb: Rename CSS::StyleProperties => CSS::ComputedProperties ... Now that StyleProperties is only used to hold computed properties, let's name it ComputedProperties.	2024-12-22 10:12:49 +01:00
Sam Atkins	4c5a40579a	LibWeb: Match spec changes to "create an element" algorithm ... Corresponds to https://github.com/whatwg/html/pull/10857 No code changes, only comments.	2024-12-18 19:22:44 +00:00
Luke Warlow	0a02eb639d	LibWeb: Implement popover's close watcher ... Auto popovers now correctly establish a close watcher when shown. This means popovers now correctly close with an escape key press. Also correctly hide open popovers when removed from the document.	2024-12-17 04:55:55 +01:00
sideshowbarker	1b165d887b	LibWeb: Support the ARIA “sectionheader” & “sectionfooter” roles	2024-12-16 06:56:31 -08:00
Andrew Kaster	7ee3727074	LibWeb: Fix compile error for popover element internal lambdas ... These were converted to lambdas in 6b921e91d4 But I merged fcf6cc27f2 without checking that the code had responded to the change.	2024-12-12 15:56:55 -07:00
