title: Disable Mouse-wheel to scroll up or down
body: <p>I have two pages, these are the conditions I cannot achieve, please let me know if it is not possible.</p>
  
  <ol>
  <li><p>In one page, I need to disable the mouse-wheel to scroll up. So when I scroll up with mouse-wheel nothing happens, but when I scroll down the page scrolls.</p></li>
  <li><p>In the other page, I want the exact opposite, I need to disable the scrolling down on mouse-wheel. So when I scroll down nothing happens, but when I scroll up the page scrolls.  </p></li>
  </ol>
  
  <p>This is all i really need, but if you think I need to explain more, please let me know, thank you.</p>
