There are currently two layout options for Wikia users - the default Wikia/Oasis layout, and Monobook. Normally, Common.css should apply to all layouts. However, when the Oasis skin was released, it was decided by Wikia that Common.css would not automatically be used. hence, you have to import common.css if you want to use it on Oasis.
