title: navbar-fixed-top show content behind Navbar
body: <p>How do you prevent the content from floating behind the Navbar when scrolling?</p>
  
  <pre><code>&lt;Navbar className="navbar-form navbar-fixed-top" responsive collapseable brand='x' inverse toggleNavKey={1} onClick={this.handleMouseDown}&gt;
  </code></pre>
  
  <p>Or is it in:<br></p>
  
  <pre><code>&lt;Nav className="navigation"..
  </code></pre>
  
  <p>Thanks</p>
