Support dark mode theming

[riyavsinha]

Would you be open to making the background fully white? And also possibly adding a "dark mode" color scheme?

I would be happy to help with this!

RE background, that is under your control. Set the background on your containing div to anything you want.

WRT dark mode, we aren't likely to have resources to take that on anytime soon.

Gotcha, yes makes sense, apologies I realized that about the background as well. I will keep this open for the dark theming in case I or anyone is able to take this on later
