Issues trying to customize theme for client

I have a client who is insisting the menu bar be centered. All efforts in the editable css style sheet have failed so far.

This client also wants pipes between the menu items. I tried adding the basic CSS code to .menuitems to do this, and the pipes never showed up. If I try using the border method, the lines are gaudy in their height!

The client also wants me removing the “read more” items and replacing them with simple links.

Are these changes beyond the scope of this theme, or is there a reasonable way to do these?

I’ve already told them about wordpress post/content opacity issues affecting images shared in posts and pages, but they’re still after me about that too.

Any help would be appreciated.
