How to change position of p-navSticky to center?

[XFFA.IR Bot]

I have changed the size of p-navSticky to fit the width of our website as below code
Code:

.p-navSticky{
     max-width: 1400px !important;
   
}

But i don't know the way to move p-navSticky to center.
Please help to check and show me the way to solve my issue.
Thanks in advanced
