Change Current Page Mini Menu Styling

Hello, Everything with this theme is really great and working well. I have a styling question. Is there a way to style the mobile mini menu to indicate which item is the current page? I am aware that the mobile mini menu heading name changes depending on the page. The way the full-size (desktop) drop-down menu items indicate the current page by displaying a black background is how I would like the current page mini menu items to be styled. I'm working local so I can't provide a link to my site. Thank you for any help you can provide.
