Center header logo

Hey all. This has probably been asked before but I couldn’t find a solution after searching through prior comments. Anyway, my problem is probably a simple one: I need to center the logo on top of the page. For the life of me I can’t figure out how to get it to align center. It re-sizes just fine for smaller devices, but if I make my browser window wider it just stays to the left. Any help would be appreciated.
