HOW to Change Gallery POPUP Background Color...?

Hi! Can someone please help me figure out how to change the color of the black background to transparent or white in the Gallery popup. (I’m referring to when site is live and an image in the gallery is selected. What happens now, is the image selected pops up with a black background so the rest of the site page can barely be seen.) I’m sure there is a code but I just can’t find one and don’t know exactly where to add it to each page. This option is available in Gallery Pro but not the plain vanilla “Gallery.” Thank you!

something like this…?
background-color: rgba(255,255,255,0);

As for the moment you don’t have access to the CSS styles of any element and the ‘plain vanilla’ settings dialog via the editor doesn’t give you the ability to change these settings… there is no way yet… maybe open a support ticket and ask that they change the style for you… I’ve got the offer for the ArtShop once… maybe worth a try…

Nothing on this?
