Extended Tooltip
What is a Tooltip
A "tooltip" is one name given to the small yellow box that appears when you hover over an object on your screen. These simple text tooltips that appear in Internet Explorer 4 (and later), Opera 5 (and later), and Netscape 6 (and later) [unless your visitor has it turned off turned off in Preferences] can be easily created by adding a title attribute to the object in your page for which you want the tooltip to appear. Tooltips will also appear in most browsers (including Netscape 4) when the alt attribute is used with an image (but this is not supposed to happen according to the standards).
This is all very well when you just want to display some simple text to describe the object being pointed at but using Javascript we can expand the capabilities of the tooltip to include just about anything that we can describe using HTML.
