title: How do you scroll the page content over a cover image (like medium.com)?
body: <p>I want to try to replicate the cover image's scroll effect found on medium.com (example: <a href="http://medium.com/@ev" rel="noreferrer">http://medium.com/@ev</a>). As you scroll down the page, the cover photo stays fixed and the content scrolls over it, covering it up as you go. Does anyone know how to do this with CSS? </p>
  
  <p>Thanks!</p>
