I'm creating a page that's mostly text. Throughout the text, there will be terms that the reader might need defined. Instead of creating a glossary, or putting an alt tag, i'd like to allow the user to be able to click the term, and have a little (preferably border-color customizable) bubble pop up with the definition. I've tried googling it, but haven't found shit. Anybody got a script i can use, or at least tell me what the correct term for this type of thing is so that i can google it more?
