What is Dynamic HTML?

Dynamic HTML is simply HTML that can change even after a page has been loaded into a browser. A paragraph could turn blue when the mouse moves over it, or a header could slide across the screen. Anything that can be done in HTML can be redone after the page loads. CSS (and plain old HTML) is what you change, the DOM is what makes it changeable, and client-side scripting is what actually changes it. And that's dynamic HTML.
