Minor wordpress header display issue in Safari and Opera - need CSS fix

I'm new at building wordpress sites and not a programmer but I can do simple css or html edits, etc. I searched through the posts but could not find any specific enough to find a solution.

I am having an issue with Safari that I first noticed on an iphone 6 plus. There are two buttons I placed in the header but Safari is adding additional bars of the same color and I want to remove them.

Is this a complicated fix?
Anyone able to give pointers or code?
