title: leaflet map not loading properly
body: <p>I use <code>leaflet</code> map in my web service but it is not loading properly. The bottom portion is not loading in fact.</p>
  
  <p>How to solve it? I just use this code:</p>
  
  <pre><code>var latlng = new L.LatLng(50.5, 30.51);
  
  var map = new L.Map('map', {center: latlng, zoom: 15, layers: [cloudmade]});
  
  var markers = new L.FeatureGroup();
  
  var london = new L.LatLng(51.505, -0.09); // geographical point (Longitude and Latitude)  
  map.setView(london, 13).addLayer(cloudmade);
  </code></pre>
