I've seen some sites where, if you move your mouse over a bit of text or click on the text, a few lines appear below it in which the webmaster can provide details about the text. I don't know what this functionality is called, so can't find it any of the script sites. Alternative would be a script which described the text in a TITLE or ALT tag format, but with larger text and scope for longer text. Thanks very much.
It's pretty easy... just make a hidden element then an onmouseover trigger toggles the display of the div between "block" and "none". You can see an example of it by going to the thing in this forum to rate a post. If you toggle between approve/disapprove you can see it in action.
