Dynamic HTML (DHTML) is an umberella term for a combination of HTML, XHTML, CSS, and a client side scripting language such as javascript, or VBScript. DHTML allows developers to create engaging web sites with content that can move, change shape, size, color, or otherwise react to user actions without requiring a trip to the web server, or browser plug-in. VTC author, Darcey Spears, shows users step-by step how to build a web site, beginning with how to acquire client information, creating a site map, and onto planning for DXHTML elements.
