Now I seem to be off and running with Drupal, but I see that on my Web-Hosted directory-tree under [/home/public_html/sites/all/themes/"CURRENT DRUPAL WEBSITE"/css]-folder there are many different css files. I am sure there is some method to this madness and these names. I also see that when I use Inspector on Firefox, that many times other css files are being brought in to manage the form of the web-page from other locations, but I don't know where these are.
I have also tried to find web-tutorials on this subject, but I can't seem to locate them. Anybody know about these Drupal mysteries or where any useful documentation might be found?
All these css-files have specific names and I am sure specific functions and they are are kept in specific locations on the folder-tree. This is what I am hoping to understand.
