If you want to impress your geek friends, start talking about the DOM (rhymes with "mom"). But first, you may want to know a bit more about what it means. The Document Object Model (DOM), part of the World Wide Web Consortium's HTML 4.0 specification, strives to make every element on a page an identifiable object. Because the properties of that object are then readable and writeable, you can use a scripting language such as JavaScript to change, hide, or move the object's attributes. For example, if object #2 is an image, you can say "Move object #2 over here" and cause an image to move across a Web page. The DOM is way cool -- it provides the method to refer to and control objects.
By defining a standard DOM, a consistent method for interacting with page elements can be achieved across platforms and browsers. This capability makes possible most DHTML effects, such as dynamically changing text and images.
Look to Dreamweaver MX 2004
