These days, web pages are rarely designed using only HTML. Thus allowing the programmer to embed scripts written in languages such as JavaScript, which many often do. This changes the look and behavior of the HTML web pages. DHTML is essentially Dynamic HTML. It is a new way of looking at and controlling the standard HTML codes and commands. DHTML is a collection of technologies that are used to create interactive and animated web sites. DHTML gives more control over the HTML elements. It allows one to incorporate a client-side scripting language, such as JavaScript, a presentation definition language, such as CSS, and the Document Object Model in HTML web page.
