What fonts actually show up for the style sheets , I've tried one or two that did not work so is there a list of fonts that work 

You will need to import from Google Fonts. I'm not sure if I can add code to this post, but message me and I will send it to you :)

google fonts has lots of different font options that you can choose from to add to your layouts or stylesheets. here are 2 examples of the font codes that I pulled from my animals stylesheets. hope this helps you out! :)
