The only issue is it really hard to read and seems to be showing up twice. Once based on the theme and once when I roll over. Is this a setting or something? And can I adjust the front? And add a background so it’s really easy to read?
This helped me with what I was looking to do as well. Is there a way to get the caption to fully overlay the image, rather than trailing off that the bottom? I have a significant amount of text, but my images are pretty small so it gets cut off.
