FYI, I don't know Drupal at all. What I've done is stick a WordPress install at /blog/ and pull in the /sites/default/css/css_randomstring.css and static html from the Drupal page - and along with the WordPress loop in the index.php file of Wordpress - somewhat integrate WordPress into Drupal. (I don't want to use the Drupal WP module).
The problem is that the Drupal CSS link changes when there are small edits from time to time on the Drupal end. (The php/html of the Drupal site isn't slated to change.)
Question: are these randomstring CSS files a cache or the active CSS file? How can I dynamically pull in the sites/default/css/css_(randomstring).css file when the string changes? Or is there a different CSS file I should be linking to?
