How to Make Text Bouncy??

So for some reason the site I just opened is not letting me use more than one font, and I used div tags and made sure it was closing? Do I need to add another font-family tag with something else?? I figured out what was wrong! Now I just want to know how execute the thing I want below :')

Also, if anyone could show me the code for making something bounce around a pre-defined area that would be awesome, especially if it can be done with a piece of text. Kind of the way the ball on pong does.
