Dynamic HTML

Dynamic HTML or DHTML designates a technique of creating interactive web sites by using a combination of the static markup language HTML, a client-side scripting language (such as JavaScript) and the style definition language Cascading Style Sheets.

It may be used to create small applications in a web browser: for example to ease navigation, to create interactive forms or to create interactive exercises to use in e-learning. Macromedia Flash is the other often used technique techniques for animating web pages. SVG could be used as well, but is not yet really supported by the major web browsers.

To the dismay of some web developers, Dynamic HTML appears difficult to develop and debug, as the different web browsers have varying degrees of support to the aforementioned technologies, and the huge range of screen sizes commonly used by clients means the end look can be fine-tuned only on for a limited number of browser/screen size combinations. However recent browsers (such as Internet Explorer 5.0 and up, Netscape Navigator 6.0 and Opera 7.0 and up) share a common Document Object Model which facilitates the use of this technology considerably, if one just writes web pages for these browsers.
