Once again, I have a book recommendation for you. And this one may be the best of any that I have picked up. Ric Shreves’ Drupal 7 Themes. This one is great. But I do have to warn you that it isn’t for novices. I started reading this one several months ago and decided that I needed to brush up on some PHP, CSS and HTML stuff, AND learn more Drupal before I could really make use of it. But if you are at that point, where the idea of adding a content type for a specific need is understood, where the files that go into a theme are reasonably well understood, then this one will be for you. This is the book that I am really going to be able to make use of going forward in my theming.
