title: Why Does The overflow-y Property Not Work With Percent Height
body: <p>I'm trying to use percentage height with <code>overflow-y:auto;</code>  and instead of creating a scroll bar on the side of the div, it's using the page scroll bar. </p>
  
  <p>Here's an example of want I'm getting at: <a href="http://jsfiddle.net/hmwe2jty/" rel="noreferrer">http://jsfiddle.net/hmwe2jty/</a></p>
  
  <p>Is it possible to use this property with percent height?</p>
