When I press the slideshow play button (in the galley feature image) I get the background (white graphic) along with the custom border that I have set for the Lightbox. What I would like to get is fullscreen with no border and a black background (and a white font) - which is how it used to work. Can anyone help me get that to work? Thanks.
Also, how do I change the Lightbox background from white to black for mobile devices only? Thanks again.
