title: How can I make a fix positioned menu bar?
body: <p>I would like to style my menu bar <a href="http://happycog.com/" rel="nofollow noreferrer">Like THIS</a>. 
  It's fixed to the top of the site when you scroll down and it isn't fixed where it is when the page is loaded.</p>
  
  <p>How can it be done with CSS?</p>
