What are CSS-1, DOM and XML?
CSS-1 provides control over the appearance of many pages at once from the typography to the behavior of links as well as precise control over page layout. DOM lets developers use scripting languages, such as ECMAScript (neĆ© JavaScript), to manipulate text, images and other parts of Web pages; for instance, dynamically changing their appearance over time, or moving them around inside the browser window. XML is a “super” markup language for many kinds of documents and activities that allows information to be passed from a Web page to any other program that understands XML. See our Resources department for more about these technologies.
