I'm trying to get an idea about how themes work and what is necessary to modify them, but when I look at the relevant styles.css files they appear to have different tags names for the same entities, so I can't figure out the atributes for a sidebar for example.

Can anyone suggest how I can figure out how any of the styles file relate to the included themes?
