Some More Definitions:Dynamic HTML and Document Object Model

Before delving into the programming there are two more topics to introduce.

The Document Object Model (DOM)

:

• Scripts can only manipulate objects on the page because of DOM
• . This was developed by the World Wide Web Consortium (W3C)
• Limited Cross-browser Support -- neither of the big players yet adheres fully to it.

Dynamic HTML (DHTML)

:

• a combination of content formatted using HTML, cascading style sheets, a scripting language and the DOM.
