title: HTML/CSS: Horizontal bar/design on sites like jQuery
body: <p>I'm sure it's just simple html/css but I don't know what to call the bar (googling horizontal bar html always results in a horizontal rule).</p>
  
  <p><a href="http://jquery.com/" rel="nofollow noreferrer">http://jquery.com/</a> has one - the grayish bar the runs across the top separating the menu from the content of the page.  I'd love to make one of my own.</p>
