title: Background error on iphone/ipad via Tumblr custom theme
body: <p>I have reskinned <a href="http://peggywho.com" rel="nofollow">http://peggywho.com</a> with a fixed background in Tumblr. However, as I am adding posts to the website, the mobile view in ipad and iphone doesn't allow the background to stretch across the page. It has black space at the top and bottom (I'm unable to add an image as I am new here)</p>
  
  <p>custom CSS for the background is as follows:</p>
  
  <pre><code>body {
  margin-top:15px;
  background-position:center center;
  background-image:url('https://dl.dropboxusercontent.com/u/2633376/PS_web_BG_01.jpg');
  background-repeat:no-repeat;
  background-attachment:fixed;
  }
  </code></pre>
  
  <p>I am relatively new to coding so still learning my way around. Is there anything to add to the HTML or CSS that would allow mobile viewing to replicate the website, which looks the way I want it to look?</p>
  
  <p>Thanks in advance</p>
