Hello. I wrote a little book (my first actually) called CSS for Windows 8 App Development published by Apress. It's available at aka.ms/cssbook. All of the code listings from the book are available in a Windows 8 app that I have created, and you can download all of the source code for this app at cssbookcode.codeplex.com. The code is not polished yet as the book is still in alpha, but it should build and run and you're welcome to take a look as early as you like. Thanks for reading my book. I wish you lots of fun and success in developing apps for Windows 8.
