How do I remove something on all pages if a user is logged in

Hi rockstars
I'd like to hide the "topbar" element (not sure if its called an element technically or not) which is the darkest color at the very top of schoolofbookkeeping.com based on a "subscriber" user login, i.e. not admin.

In other words, if the logged in user cannot manage options or edit posts, hide this particular area of a page on all pages. Better?
