title: How do I scroll an overflowed div to a certain hashtag (anchor)?
body: <p>On my webpage I have an overflowed div (i.e. with the vertical scrollbar). Inside the div, I have anchors with ids. When I put one of these ids in the URL (mypage.html#id), I want the div, not the page, to scroll to that anchor.</p>
  
  <p>How do I do that, preferably with plain JavaScript? If it's too complex, I'll go with jQuery, but I'm not using it in this project for anything else.</p>
