JQuery - FadeIn + MarginTop

I'm trying to get something like this (http://www.hy开发者_如何学Godroholistic.com/, when you hover the logo a box appears fading and animating) what do I have to do for something like that?

You can find a lot searching for jQuery Tooltips.

Like Shawn said, try searching for jQuery Tooltips and then just add your own skin/styling. The implementation stays the same however, very easy.
