You mean fonts I assume? Remember, with fonts no matter what you specify, they will only display if the customer has them on their computer, so you are pretty limited. You can certainly specify some funky font, but if it isn't on the users computer it will default to something else like Arial. Have a look at this:

You can specify all fonts in your skin1.css file.
