title: Prevent "overscrolling" of web page
body: <p>In Chrome for Mac, one can "overscroll" a page (for lack of a better word), as shown in the screenshot below, to see "what's behind", similar to the iPad or iPhone.</p>
  
  <p>I've noticed that some pages have it disabled, like gmail and the "new tab" page.</p>
  
  <p>How can I disable "overscrolling"? Are there other ways in which I can control "overscrolling"?</p>
