Drupal uses CSS for styling. Sure. But how? Drupal has dynamic content and not static html pages that have style sheet references in them. that’s where i am today.
This is a good reference for this from Adaptivethemes
Look to the .info file for your theme or module to specify what CSS files will be used.
But, how does the internal aspects of the css file tie to the outputted HTML?
Look to the .tpl file
