I want to create little ? icons that when you hover over them or click them, they show a little notification. Kind of like when you hover over a link with title, it'll show what the title is. Well in this case, I'd like it to show a few sentences giving people some information.
I tried searching for how to do it, but I guess I just don't know what to search for, because I couldn't find anything :(
Could someone tell me how this is done?
