background-image not displaying in .content div after adding page to home screen (iPhone 4)
I added the following css to <code>.content { }</code> in ratchet.css

  <code>background-image: url('../img/cartraffic2.png');
  background-repeat: no-repeat;
  background-position: fixed;
  background-position: center top;</code>

When I open the page from my iPhone browser, the background-image is correctly applied to the main content div. When I "Add to Home Screen" and open the page from there, the image is not applied to the main content div.
