Start from Zero. Create one and only one main navbar (without any non-symbol parents - and thats it).
Get inside this templates and see how it works:
Absolute position VS padding/margin - in general you get the same result (If you use left: 50; or margin-left:50;) - but most of the times for Absolute elements its easier to work with top/right/bottom/left.
