I feel dumb asking this, but it’s already taken too much time and I can’t figure it out.
On a site I’m building, I’m getting a simple black border showing up between the header and the body. I’ve looked at every possible element in both the body and the header that could have anything to do with a black horizontal line between the two and I can’t find anything.
Nothing is set to have a border, it’s not a divider, etc.
