Wisdom.DHTML
DHTML (Dynamic Hypertext Markup Language) is a vaguely defined term implying the creation and animation of dynamic, interactive elements in HTML pages, using CSS and Javascript.
DHTML effects are at their best when the can gracefully degrade, simply augmenting web pages when Javascript and advanced browser features are available, and failing silently and unobtrusively when they are not.
