I have tried the several suggestions but to center primary menu buttons but to no avail. I've also posted for help on this a couple of times under Oxygen theme (that's the theme I modified) but haven't received any responses.
Could you please help me out with some advice on how to center the primary navigation buttons for this (test) site:
