On some sites and game, when you hover your mouse's curser on an image or word. A box containing words/pics/stuff appears where your curser is and when you move your curser away from that word/image the box disappears. How do you do that?
On a side question:
That costs $1.99 USD per month (2$), is it necessary to run simple simple ajax (getting info from server without loading page) or to run what i asked for at the begining of this post. Because i already paid for it twice and iam gona pay for it on 1/1 and i still don't know if its a necessity. Cuz if its not, iam just burning money since iam not using any advanced java functions/applications.
are two completely different things that have no connection whatsoever. This is something that is usually confusing for those who are entering the world of web programming, so it's best to deal with the problem right away.
