Thank you, Bryant! For Pages that would definitely work, but I'm looking to add to either Galleries or implement the change using Site Styles, I haven't seen a way to add a Line using the cms tool in those areas. Do you know if that's possible?
Is it possible to add a Line below Gallery images on Flatiron? I would like to add a Line between the Gallery and the Index Grid that displays below to visually separate the two. Is there custom CSS or HTML that would accomplish this goal?
