Sam Atkins bc00ef8314 LibWeb/CSS: Replace Parser "current property" with a stack of contexts
`current_property_id()` is insufficient to determine if a quirk is
allowed. For example, unitless lengths are allowed in certain
properties, but NOT if they are inside a calc() or other function. It's
also incorrect when we are parsing a longhand inside a shorthand. So
instead, replace that with a stack of value-parsing contexts. For now,
this is either properties or CSS functions, but in future can be
expanded to include media features and other places.

This lets us disallow quirks inside functions, like we're supposed to.

It also lays the groundwork for being able to more easily determine
what type a percentage inside a calculation should become, as this is
based on the same stack of contexts.

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.
