Good book to check out on this is "Pro CSS and HTML Design Patterns" - http://www.amazon.com/Pro-CSS-HTML-Design-Patterns/dp/159059...

The author uses OO-based css examples all throughout the book, it was my first time reading about it and thought it was pretty cool. You could read through the descriptions on Amazon to get the general idea.
