DOM Tooltip allows developers to have dynamic and configurable tooltips on HTML pages. This library supports Mozilla/Netscape6+, IE 5+, Konqueror and Opera 7. The tooltips are configured through three class definitions in a stylesheet, and consist of two parts, the caption and the content. Tips can be either greasy, sticky or velcro, where sticky tips remain after mouseout of the object and require a click to close, velcro tips close when you mouse out of the tooltip and greasy close when you mouse out of the target that created it. The tooltips cannot even popup embedded windows onload.
