DOM

The DOM is a specification under development by the W3C. It will allow all elements of a Web page--graphics, text, headlines, styles, and so on--to be manipulated and acted on by programs and scripting languages (such as JavaScript and VBScript). For example, the DOM makes it possible to define each individual letter on a Web page as an object, and then to assign separate qualities such as color, size, and style to each letter. The DOM is one of the core technologies that make up DHTML, along with Cascading Style Sheets (CSS), traditional HTML, and scripting languages.
