Hovering HTML Windows and Animated Hovering Using JavaScript

Hovering HTML Windows and Animated Hovering Using JavaScript: "You have probably seen many web sites with windows that seem to appear out of nowhere on the screen. Often if you just mouse over something, a custom window will pop-up near the mouse-over position of your screen pointer. This is done with an HTML tag called <SPAN used along with JavaScript. Also you have probably seen animations and images within HTML pages that seem to appear and hover over the whole page; that also is done with this <SPAN and JavaScript animation method. It is important to know general JavaScript to animate <SPAN windows within HTML pages, but you can use my example below for most <SPAN tag animations."
