title: Leaflet custom control to open text box on click
body: <p>I have followed <a href="http://www.coffeegnome.net/control-button-leaflet/" rel="nofollow noreferrer">this Leaflet tutorial</a> on how to create a control button for my map.</p>
  
  <p>When clicked, I would like it to open a simple text box containing information about the map and its authors, similar in concept to that of the info button on <a href="http://mtbmap.no/#6/63.400/10.390" rel="nofollow noreferrer">this map</a>. </p>
  
  <p>Any help is appreciated.</p>
