Which templates display captions in galleries on mobile

I would like to know which templates show captions in galleries on mobile- I’m using sonny (Brine) and there’s no caption in landscape or portrait mode. Is there some code or a work around? Or perhaps a different way of doing things. My client is a jeweller who wants to display her collection with captions and just can’t have anything else... other than drawing up a page with photos and text I’m struggling to work out how to do this....

You can check templates from  whatsgbplus.com
