Meta: Add license header to source files As suggested by Joshua, this commit adds the 2-clause BSD license as a comment block to the top of every source file. For the first pass, I've just added myself for simplicity. I encourage everyone to add themselves as copyright holders of any file they've added or modified in some significant way. If I've added myself in error somewhere, feel free to replace it with the appropriate copyright holder instead. Going forward, all new source files should include a license header. 2020-01-18 09:38:21 +01:00			`/*`

Everything: Move to SPDX license identifiers in all files. SPDX License Identifiers are a more compact / standardized way of representing file license information. See: https://spdx.dev/resources/use/#identifiers This was done with the `ambr` search and replace tool. ambr --no-parent-ignore --key-from-file --rep-from-file key.txt rep.txt * 2021-04-22 01:24:48 -07:00			`* SPDX-License-Identifier: BSD-2-Clause`

LibWeb: Move HTML object model stuff into LibWeb/HTML/ Take a hint from SVG and more all the HTML classes into HTML instead of mixing them with the DOM classes. 2020-07-26 15:08:16 +02:00			`#include <LibWeb/HTML/HTMLBlinkElement.h>`
LibWeb+WebContent: Add abstraction layer for event loop and timers Instead of using Core::EventLoop and Core::Timer directly, LibWeb now goes through a Web::Platform abstraction layer instead. This will allow us to plug in Qt's event loop (and QTimer) over in Ladybird, to avoid having to deal with multiple event loops. 2022-09-07 20:30:31 +02:00			`#include <LibWeb/Platform/Timer.h>`
LibHTML: Implement the <blink> element Just in time for Serenity's 1st birthday, here is the <blink> element! This patch adds a bunch of different mechanisms to enable partial repaints of the layout tree (LayoutNode::set_needs_display())) It also adds LayoutNode::is_visible(), which can be toggled to prevent a LayoutNode from rendering anything (it still takes up space though.) 2019-10-09 21:25:29 +02:00
