CSS code for changing whit background

Hello there,

You guys have one impressive plugin, here. The one detail, though, that I’m surprised is unavailable in any of the settings (unless I missed something) is the option to change the white background. With a site like mine that has a black background, the white is very unsightly. Is there a CSS code I can insert that will change the background to transparent? Transparent would be best, otherwise black would work. Thank you, in advance, for your help!
