A look at Drupal 7 Theming from Aimee Maree Forsstrom

Drupal Theming inheritance

what I am doing now is tracing the inheritance of drupal themes. starting with the stark theme, which only uses two individual files (layout.css and stark.info) through more complicated themes that have many .tpl.php, .css files and other preprocessor functions. this will help me to fully understand what i need to modify in order to make a theme of my own.
