Here is the link. Good on desktop, doesn’t show responsively on mobile. The only type of caption I can get to show on mobile is to use the pop-over which is tough on mobile.
Thanks, Tom. New at this. Can you direct me to a link for the optimal way to add this to CSS. I assume I would not want to add this to one of the existing PHPs (or the bold grid gallery plug-in) as it would get clobbered if I update the plug in version later.
