I'm not sure this will help you Song, but here is a talk I gave a
couple years back which talks some about the DOM vs. Rendering tree
Best of luck in your exploration.

> The DOM tree needs to match the document structure and can’t be influenced by style. This is what makes the DOM API work; the DOM tree is a parsed form of the document explicitly exposed as API. Style can change many ways at times when the DOM must not change, for example, when a stylesheet finishes loading, the styles from that sheet can affect how the DOM elements are displayed. We can’t change the DOM tree in response to style changes.
