indent all text in Content; change sidebar width; remove widget from header

Hi. 1. Is there CSS code that I can use to indent all text in the content section, or pad the content? 2. Is there a way to narrow the width of the sidebar? Maybe this is an option in Pro? 3. How can I remove the social widget from the header, but keep it in the footer? (not needed in 2 places...) Thanks. Alice
