What is Dynamic HTML or DHTML?

Dynamic HTML is an extension of HTML allowing greater control over the page layout and positioning. DHTML also allows greater interactivity without depending on interaction with a server. When we talk about DHTML, we usually mean the combination of HTML 4—as defined by the W3C Web standards organization—and cascading style sheets (CSS). These elements work together through a scripting language, usually JavaScript.

Note

Internet Explorer and Netscape have defined DHTML differently through different DOMs (Document Object Models). For more information on the various flavors of DHTML, try Microsoft's site: http://msdn.microsoft.com/workshop/author/default.asp, Netscape's site: http://developer.netscape.com/docs/manuals/communicator/dynhtml/, and (for an "official" answer) the W3C site: http://www.w3c.org/DOM/.

Despite the two browser DOMs, Dreamweaver generates HTML code that works with both browsers.
