You can go into the Style Property >> Header & navigation and tinker around in there or do it through your EXTRA.CSS template. If your attempting to move the visitorTabs, I know forsaken wrote a guide on how to move this if that's what your attempting.
Unsure what your trying to do to be honest. If your trying to replicate the first screenshot navbar/Tabs, you would be best to ask the author where you screen capped that and ask how he/she accomplished it.
