InvalidUsernameException fb9286eccb LibWeb: Apply clip frames even when transformation is identity
Clip frames for overflow were applied based on whether the box in
question had a non-identity matrix transformation associated with it.
That however is not correct, since specifying a no-op transform like
`scale(1)` still needs to apply clip overflow rectangles. So instead we
need to check whether the element associated with the box in question
has any CSS transforms.

This appears to have been a regression from
9bbc1cd618 and effectively reverts that
commit, but keeps its effect by unifying on the check for CSS transforms
instead.

This fixes some background boxes being rendered for the invisible items
of the carousels on https://computerbase.de/.

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.
