Centering menu items on navigation bar

You want to to vertical centering or horizontal centering?

this *may* work. It raises the menu items by 10px but not the first one (the logo)

#nav-wrapper .menu li {
    margin-top: -10px;
}

#nav-wrapper .menu li:first-of-type {
   margin-top: 0;
}

To add CSS: If your theme has a custom CSS option, use that to add the CSS shown above. If not, install the plugin Simple Custom CSS. Or, if you have Jetpack installed, enable its Custom CSS module.

Learn the Chrome Developer Tools to help you see and test changes to your CSS.

OK, let’s try replacing that 2nd block with

.menu-item-1360 li { margin-top: 0 }
