Meet the DOM

Just what is the DOM? According to the World Wide Web Consortium (W3C) (http://www.w3.org/DOM/), the DOM is a browser-independent, platform-neutral, language-neutral interface that allows “programs and scripts to dynamically access and update the content, structure, and style of documents. The document can be further processed, and the results of that processing can be incorporated back into the presented page.”

In simple English, the DOM makes other standard components of your page (style sheets, markup elements, and scripts) accessible to manipulation. If your web page were a movie, XHTML would be the screenwriter, CSS would be the art director, scripting languages would be the special effects, and the DOM would be the director who oversees the entire production.
