Color customization question

tsinsf

I would like to add a solid black rectangle around my Slideshow, as if the Slideshow content block was a photo set on top of a larger solid black rectangle. I would like to do the same thing with my Gallery content block and have the two black rectangles controlled independently from each other.

Thanks!!

Hi Tony,
I'll ask the moderators to move your thread over to the New SmugMug customization forum so the customization experts can take a look if there might be a way to do what you're looking for.
