Change Background Color in SmugMug Lightbox

SmugMug recently changed the code for the Lightbox. They also added some basic Custom CSS, like changing the background of the Lightbox. It’s great except it has some “holes” (original colors) in it, especially in the Cart section. So if you’d like to change the Lightbox from a light color to a dark version, like I’m currently using, you’ll need to add this to your theme’s custom CSS section. Feel free to change the colors to suit.
You’ll notice the first section cursor: default;. I noticed a bug when doing this, so I added the default cursor when you hover an active page.
