help positioning an object

[dtrachtman]

I want the navigation for my site to be fixed to the top of the page, but move horizontally with the content in the page (and not scroll). The content is centered. I've tried all the permutations I can think of. Any ideas?
thanks

Not exactly sure what you want, but maybe

.head-wrapper { 
  position:fixed; 
  top:0;  
  width:100%;
}

header { 
  width:50%; 
  margin:0 auto; 
  background-color:#ccc;
}

  <div class="head-wrapper">
     <header>
       this is the header
    </header>
  </div>
