title: Element disappears as soon as I make its position absolute
body: <p>I'm trying to place <code>.blob</code> at a particular position inside a container behind an image.</p>
  <p>The blob shows up in the container quite fine but as soon as I make it <code>position: absolute</code>, the blob disappears. The container position is relative and the image position is absolute:</p>
