What is dHTML?

dHTML stands for dynamic Hypertext Markup Language.

The World Wide Web Consortium (W3C) defines dHTML as "a term used by some vendors to describe the combination of HTML, style sheets, and scripts that allows documents to be animated".

In other words, dynamic HTML is not a specification. It is an implementation of HTML that uses the language in combination with a document object model (DOM), a scripting language like JavaScript and cascading style sheets.
