title: Infinite scroll in Elm
body: <p>I am building a simple application in Elm that show just a list of divs one under the other, and I would like to add infinite scroll functionality, to add new content every time the last div of the page appears in the viewport.</p>
  
  <p>Is there a way in Elm to know when a div appears in the viewport? As an alternative, in there a way to track, as a signal, the mouse scroll event?</p>
