I used the information in this forum to create my centered nav and it worked great:
However, now when I try and add this centered nav as a symbol or just copy and paste onto a new page, the logo shifts back to the left-hand side. Any thoughts?
It is all about “Current” state for the logo link.
On the Home page Logo link has state “Current” (as expected) and in this state there is setting float: none. Remove this setting (float will become LEFT) and you will fix the issue.
