This may be more of a philosophical question. I'm a Drupal newbie (developer and themer), and I'm considering switching our current project's theme from Fusion to Omega.
The Omega theme contains several default CSS files. I have created a sub-theme to capture all my customizations. If I want to override some of the settings in one or more of the default CSS files, is it better to:
(1) Enable the theme's CSS file. Create my own version of the theme's CSS file in my sub-theme folder - e.g., mytheme-custom.css - and only include overrides and additional settings in the file. -OR-
(2) Disable the theme's CSS file. Copy the theme's CSS file to my sub-theme folder, rename it if I want, and add/modify/delete whatever I want. -OR-
(3) Some other option.
Is one approach better than another? Thanks for your help.
