styles.css – primer

Hello everyone,

I am looking for an explaination of what is going on in the styles.css of most themes.

Specifically, I want to know how to reduce the spacing around the sidebar in the “Gentle Calm” theme, but a general explaination of what is going on in styles.css would help me with future troubles as well.

I noticed there is a Wiki http://wiki.wordpress.org/wp_get_archives for WP topics, but couldn’t find anything about the styles.css file.

Thanks for any help!
