Forum How do I change styles for 4.0.4?
 

I feel like an idiot but I'm really confused as to how to change basic style options for the forum I just installed. I've noticed that "main css" is obsolete and read somewhere that we now need to go to "stylevars". So I did that and tried to change the body_background under "commons" and nothing changed after I saved.

Where do I go to change the styles? Or is there anywhere I can just enter in the css I want that will override what's already set?
