Collapsing navbar content margin - span class bars

I have been working on this navbar template for a few days. Almost done, but it is not just as I wanted. Navbar is working fine, but how can I overcome spaces on four sides: 3px on the left (most probably 1px border+1px space+1px border) 10px on top, 10 px bottom, 33px on the right. Can you help me overcome them?

Second, Span class bars are not showing, the same code works on another page? What am I missing?

Here is the example of my template:
