HTML Parsing Source Code:
The actual code in the browser responsible for constructing the DOM from HTML, that's part of the browser's engine:
For Chrome, it’s Blink (an open-source project): https://chromium.googlesource.com/chromium/src
For Firefox, it’s Gecko: https://searchfox.org
For Safari, it’s WebKit: https://webkit.org
These engines are written in C++ and can be explored in their respective repositories:
Each engine contains sophisticated parsers and renderers to create the DOM.

Happy sophisticated coding
