Please guide me what is wrong I am doing?

Answer 1

In order to correct the position of the links, i changed the order of the navbar elements, first the left side, then the right side ( it was not the problem, its a matter of organization). Added a division between the nav & the page title. Changed the class of the navbar items on the left to :
<ul class="nav navbar-nav navbar-left">
Instead of just
<ul class="nav">

I know its simple, but if you expand the window you will see that it works just right
