Broad shadow-root stylesheet changes already restyle the whole shadow tree, but host-side fallout does not always need a document-wide invalidation. Split the host-side reach classification so selectors contained to the host subtree, such as `:host *` and `:host > *`, invalidate the host, while sibling-escaping selectors such as `:host + :has(*)` still invalidate the host's root. Recognize sibling escapes through positive selector-list pseudos such as `:is()` and `:where()` as well, including selectors like `:is(:host) + :has(*)` and `:is(:host + .item)`. This avoids turning host-contained shadow stylesheet changes into full document style invalidations. On https://pomax.github.io/bezierinfo/, this reduces the time to produce a layout tree from about 8.7s to 3.6s on my machine. |

Ladybird
Ladybird is a truly independent web browser, using a novel engine based on web standards.
Important
Ladybird is in a pre-alpha state, and only suitable for use by developers
Features
We aim to build a complete, usable browser for the modern web.
Ladybird uses a multi-process architecture with a main UI process, several WebContent renderer processes, an ImageDecoder process, and a RequestServer process.
Image decoding and network connections are done out of process to be more robust against malicious content. Each tab has its own renderer process, which is sandboxed from the rest of the system.
At the moment, many core library support components are inherited from SerenityOS:
- LibWeb: Web rendering engine
- LibJS: JavaScript engine
- LibWasm: WebAssembly implementation
- LibCrypto/LibTLS: Cryptography primitives and Transport Layer Security
- LibHTTP: HTTP/1.1 client
- LibGfx: 2D Graphics Library, Image Decoding and Rendering
- LibUnicode: Unicode and locale support
- LibMedia: Audio and video playback
- LibCore: Event loop, OS abstraction layer
- LibIPC: Inter-process communication
How do I build and run this?
See build instructions for information on how to build Ladybird.
Ladybird runs on Linux, macOS, Windows (with WSL2), and many other *Nixes.
How do I read the documentation?
Code-related documentation can be found in the documentation folder.
