custom-css custom coding to adjust background opacity and adding captions in Lightbox mode

Site URL: https://www.1053maingallery.com/

I would like to adjust the Lightbox of my gallery pages to do two things:

1. Make the  background of light box completely opaque white so you do not see the thumbnails of the gallery at all. I currently have it at the highest opacity setting SS allows without adding custom code and I don't like how the background interacts with the Lightbox.

2. Be able to view the captions (title of artwork) when you open in light box - preferably on hover.

Thank you.

Hey @claire.gilliam try to add next code in Custom CSS:

.gallery-lightbox-background {
  opacity: 1;
}
