How do i remove the navMainWrapper? The top bar that was blue but now changed to white?

I did this since it adjust the search bar I needed to make further changes. It looks like it worked so hopefully this helps someone else

#navMainSearch {
float:right;
margin-right:-400px;
margin-top:90px;

and

#navMainWrapper

Height: 0
