How to change css background?

[chrismaddox3d]

My site color is not that great and i wanna change it,
I found my stylesheet.css but do not know what to change,
Want my site to have a white back ground,
Maybe different color buttons if orange wont work with white,
Would this be done in the css or the back ground image in ps,
Here is the link to my site, http://www.youniverseonline.com
hope someone can help,
Thanks,

Depends on exactly what you want to change. For example, if you want to make the area outside your mainWrapper white, you would look in stylesheet_tm.css and change the background color in the body rule from 1e1e1f to ffffff.
