Getting sitepoint sample code to work

I recently bought a copy of “build mobile websites and apps for smart devices” and i have tried to run the sample download code from the sp site (app/index.html). I have put it on a server on the web. It seems to render ok in a FF browser on the desktop, but on both by android samsung galaxy 10.1 tablet and my iphone 4, i get the page but not the styling. It would be great to see the final thing on these platforms (if I am doing it right) before I start on my own journey. Any ideas how to run this code? thanks.

Is it possible for you to past link to what you have so we can take a look?
