title: reactstrap <Navbar> fixed on top
body: <p>I'm using reactstap and try to implement a navbar being fixed, which works partially, since the navbar is fixed, but the very next component moves to the top (behind the navbar). If the fixed attribute is not set, the content appears correctly below the navbar.</p>
  
  <pre><code>&lt;Navbar className="bg-dark" color="dark" fixed="top" &gt;
  </code></pre>
