<h3>Leaflet on Mobile</h3>
<p>In this example, you'll learn how to create a fullscreen map tuned for mobile devices like iPhone, iPad or Android phones, and how to easily detect and use the current user location.</p>

<h3>Preparing the page</h3>
<p>First we'll take a look at the HTML & CSS code of the page. To make our map <code>div</code> element stretch to all available space (fullscreen), we can use the following CSS code:</p>
<pre><codeclass="css">body {
padding: 0;
margin: 0;
}
html, body, #map {
height: 100%;
}</code></pre>
<p>Also, we need to tell the mobile browser to disable scaling of the page and set it to its actual size by placing the following line in the <code>head</code> section:</p>
<p>We'll now initialize the map in the JavaScript code exactly like we did in the <ahref="quick-start">quick start guide</a>, but won't set the map view yet:</p>
<pre><codeclass="javascript">var map = new L.Map('map');
var cloudmadeUrl = 'http://{s}.tile.cloudmade.com/YOUR-API-KEY/997/256/{z}/{x}/{y}.png',
cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18, attribution: cloudmadeAttribution});
map.addLayer(cloudmade);</code></pre>
<h3>Geolocation</h3>
<p>Leaflet has a very handy shortcut for zooming the map view to the detected location, replacing the usual <code>setView</code> method in the code:</p>
<p>Now we have a working fullscreen mobile map! But what if we need to do something after the geolocation completed? Here's what the <code>locationfound</code> and <code>locationerror</code> events are for. Let's for example add a marker in the detected location, showing accuracy in a popup, by adding an event listener to <code>locationfound</code> event before the <code>locateAndSetView</code> call:</p>
<p>Now the example is complete — try it on your mobile phone: <atarget="_blank"href="mobile-example.html">View the full example →</a></p>
