title: How to scroll only a second div with no height specified
body: <p>I have a HTML page with 2 divs. The first one I need it to contain an image with 100% width and auto height (so that it keeps the aspect ratio).
  The second one contains a list. 
  I want to scroll only the list and keep the image visible.
  This is <a href="https://jsfiddle.net/u5xwta4b/" rel="nofollow">the fiddle that I tried.</a> But nothing seems to work. 
  I really think there is a simple solution but my CSS skillz are at beginner level. I tried <code>style="/* overflow: auto; */position: relative;/* height: 100%; */</code> but no luck</p>
  
  <p>LE: I want the list to begin AFTER the image - so the scroll will start somewhere after the image</p>
