Dark background white content area?

Does anyone know if it's possible to have the background set to black but keep the content area white?

I'm aware of the container option, however I don't want the container going through all the mod positions vertically, just the content area.

Any help would be much appreciated.

Content container has class .content_sparky so you can place this

.content_sparky{
background:white!important;
}

at bottom of template_css.css

and set background to black from template options

Works great, thanks.
