Web Browser Engineering

The excerpts provide an extensive overview of the complex field of web browser engineering, starting with the historical context of the web's foundational technologies like HTTP and HTML. The text details the iterative process of building a simplified browser, covering core functionalities such as network requests (including sockets and HTTP status codes), rendering (layout, text formatting, and graphical user interfaces like SDL/Skia), and styling with CSS (parsing, cascading, and inheritance). Furthermore, the source addresses sophisticated topics crucial to modern browsers, including JavaScript execution (DOM manipulation and event handling), security features (CSRF, XSS, and Content-Security-Policy), performance optimization (multi-threading, rendering cadence, and incremental layout using techniques like ProtectedField), and accessibility features like zooming and dark mode. Finally, it explores the implementation of complex embedded content, notably images and iframes, which introduces the concepts of cross-origin communication and site isolation.
