title: Does HTML (source code of a web page) changes when the page is saved to a local computer?
body: <p>I opened a webpage (<a href="http://www.designova.net/rise/index-01.html" rel="nofollow">http://www.designova.net/rise/index-01.html</a>) and viewed its source code. And then I saved the page to my computer and then opened it in an editor (sublime text 2). Now the HTML content in two files are different. I assume this is deliberately done but I am not sure why.</p>
  
  <p>Among the two HTML versions, which is the reference HTML I can use in case I want to develop a similar webpage?</p>
  
  <p>The difference is not only in URLs but also additional code snippets are added when downloaded.</p>
  
  <p>Original body tag: <code>&lt;body&gt;</code></p>
  
  <p>After downloading: <code>&lt;body class=" pace-done"&gt;&lt;div class="pace  pace-inactive"&gt;</code></p>
