title: How to change the scroll speed of a div
body: <p>I need to change the scroll speed of two <code>divs</code> (out of 5 divs). 
  I found how to change it for the whole document: <a href="http://jsfiddle.net/36dp03ur/" rel="nofollow">http://jsfiddle.net/36dp03ur/</a></p>
  
  <p>But what I need is something like this:</p>
  
  <pre><code>    &lt;div id="1"&gt; //scrolls normally
       ...
      &lt;/div&gt;
  
      &lt;div id="2"&gt; //scrolls slower 
       ...
      &lt;/div&gt; 
  
      &lt;div id="3"&gt; //scrolls normally
       ...
      &lt;/div&gt; 
  
  and so on
  </code></pre>
