I'd like to make my whole site wider, as since the content has grown, the navigation tabs and Facebook feed content appears crammed. I recently purchased the customization upgrade, but have little experience writing my own CSS. Any suggestions for easiest way to expand width? Currently using the Blix theme, although may change theme at some point, although it's my understanding that custom CSS page will override theme CSS.
The blog I need help with is familypromisepalouse.org.
