Before this change, whenever element's attributes changed, we would add a flag to "pending invalidation", indicating that all descendants whose style uses CSS custom properties needed to be recomputed. This resulted in severe overinvalidation, because we would run invalidation regardless of whether any custom property on affected element actually changed. This change takes another approach, and now we decide whether descendant's style needs to be recomputed based on whether ancestor's style recomputation results in a change of custom properties, though this approach adds a little overhead to style computation as now we have to compare old vs new hashmap of custom properties. This brings substantial improvement on discord and x.com where, before this change, advantage of using invalidation sets was lost and we had to recompute all descendants, because almost all of them use custom properties. |

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.
