A large percentage of Chromium’s code (and part of what makes it so fast) is WebKit. In this talk, Eric Seidel gives us a 30,000 foot view of how WebKit actually renders a page. He starts with how resources are loaded, explains how they’re parsed into a DOM tree, and then talks about the various trees involved in rendering. In addition, he touches on many other important topics like hit testing (figuring out what you’re hovering over and clicking on). This is a must-see for anyone working on the guts of WebKit.
