Dark theme vs. Light theme

I currently have the plugin turned off (with my usual FB Comments tool turned on), though i can turn it on for troubleshooting if need be. I’ve included a linked page so you can see what my theme otherwise looks like.

What I’m looking for is simple. Every other facebook comments plugin I’ve ever tried had a basic, binary option in their settings, allowing for a “dark” or “light” theme for the plugin, depending on one’s needs. I came to experiment with this plugin because it somehow restores the correct targets to old facebook comments, prior to becoming SSL compliant. I tried it, saw that it works, and thus was otherwise sold as a solution, apart from the fact that I have a dark themed site, so the default settings are not good…and though you’ve added a variety of styling options that I’ve not seen offered with this tool before, the only way to get the text to be legible on my site is to pick a white background, which is just too jarring on my site.

I see that you allow for additional css. Do you guys have a straightforward bit of css that would give the plugin that standard, “dark” theme? If so, that would solve my main issue. Also, why is this not a default setting option, given that it is otherwise quite common to see?

Thanks,
Eric
