Remove Shop Banner

Hello WordPress Community! I would really appreciate your help with my issue. There is a large black banner at the top of my web page at https://bedighted.com/shop/ that shows the title “Shop”. I would like to remove this banner because it is taking up a large amount of room, especially when people navigate to my site using mobile devices. Could you please provide code that I can paste into the Additional CSS section that will remove this banner? I know a little basic C++ but no CSS so I would be especially grateful if you would supply the entire code that I need to paste. Thank you in advance for your help.
