Tool-tips...

I have a form where users enter information into. I want to create tooltip-type hints that when they put the mouse over the input field, or when they are making an entry into it, the tool-tip will appear right below it showing some instructions.

I would like them to look similar to the little yellow box that appears when you hover your mouse over the name of the user's online on the left column of this page.

Any ideas?

use the title property...

<input type="text" name="name" title="enter your name here"/>

note: this does not work with select boxes

Cool. This sort of works. But I need to expand further because I need to make something appear when with selects also. Also, the title doesn't always appear if you are alrady making an entry into the input. I want to somehow have this tip appear whenever the mouse is moved over the object or if the object is currently in focus. It would also help if I could somehow format the tip.
