This is the source code to Web Browser Engineering, my book on how web browsers work. The best way to read the book is online.

If you want to build from source, run:

make book draft blog

The source code contains:

• The Markdown source for the book text, in book/
• A template and code for converting the book to HTML, in infra/
• Chapter-by-chapter implementations of the browser, in src/
• Styling for the book's website, in www/
• The book's built-in feedback system, in www/, including JavaScript and the Python backend.

We prefer to receive typos and small comments on the text using the book's built-in feedback tools, which you can enable with Ctrl+E.

We're always happy to hear from readers and from educators who want to use the book. Please email us!
