Hello!

I was wondering if someone could help me as I have no previous coding experience.

I am trying to move one item to the other side of the navigation bar and am unsure of how to do this. The navigation bar currently looks like this, however I need the phone number to be on the other side (left of the Book Online button).

Thank you!!!
