XF 1.5 Center Tabs in Navigation Bar

Hello, I was wondering how I would be able to center my navigation bar rather that it being left justified.

How could I do this via the EXTRA.ccs file?
I am on PC, using Chrome, on Windows 10.

I tried putting
.navTabs .publicTabs {
    padding: 0 50px;
In the EXTRA.css, put it just moves it 50px to the right.
