I am preparing a web page with more data that can possibly be shown without making the page really cumbersome. I am considering different way to do this. One way would be to have the extra data magically appear on a small window when the user hovers over a particular part of text.Yahoo! Answers does something like that when you hover over a user. But I suppose that must be way to complex to code (for my level).

SO I am looking for a simple way to get a small pop up window to appear next to the mouse pointer when the user hovers on a particularly interesting text. The window should disappear automatically once the user leaves the text.
On this topic I have a few questions:

• How can this be done?


• Can it be done without using JavaScript?


• What other solutions should I consider? (For example I have seen some web pages expand some sections, when the user hovers click on them)
