small text like a hint popup?

[grimbys]

Hi! I'd like to make a page with the next behaviour:
If it is possible using CSS ...

Example:
...
<STYLE>
SPAN.NUMBER {background:green}
</STYLE>
...
<SPAN CLASS=&quot;NUMBER&quot; XXX=YYY> 888 </SPAN>
...

When I put on mouse over 888, I'd like a small textbox (a comment / hint and not a edit textbox) popup

If you didn't understand, I made a Ms Word Html example

I'd like the popup over &quot;hello&quot; and not over JBT1.

I don't have idea about web programming.
Thank you.

Note:
I'm sorry I duplicated this post, (before in Javascript), I think here is better for this question
