leaflet.js map is not showing up
<p>I am a newbie to <code>leaflet.js</code>. Can anyone help me with debugging the following code? I am trying to show a map on screen but only zoom-in and zoom-out button  shows up on Google Chrome and the map screen is empty.</p>

<pre><code>&lt;!DOCTYPE html&gt;
&lt;html lang="en"&gt;
    &lt;head&gt;
        &lt;link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.css" /&gt;
        &lt;style&gt;
            #mapid { height: 180px; }
        &lt;/style&gt;
    &lt;/head&gt;

    &lt;body&gt;
        &lt;div id="mapid"&gt;&lt;/div&gt;
        &lt;script src="http://cdn.leafletjs.com/leaflet/v0.7.7/leaflet.js"&gt;&lt;/script&gt;
        &lt;script&gt;
            var mymap = L.map('mapid').setView([51.505, -0.09], 13);
        &lt;/script&gt;
    &lt;/body&gt;
&lt;/html&gt;
</code></pre>
