XF 1.3 .PanelScroller .navControls / how to make it "centered" ?

[erich37]

I would need a hint of how to change the "navControls" (the small Tabs at the bottom-right which show when you have more than one "Notices") from position "right" towards position "centered".

.PanelScroller .navControls {
    float: right;
}

Many thanks!
