<div class="announcement">Nov 21, 2016 — <a href="http://leafletjs.com/2016/11/21/leaflet-1.0.2.html">Leaflet 1.0.2</a>, a bugfix release, is out.</div>

<div class="announcement">Sep 27, 2016 — <a href="http://leafletjs.com/2016/09/27/leaflet-1.0-final.html">Leaflet 1.0</a>, the fastest, most stable and polished Leaflet release ever, is finally out!</div>

<p>Leaflet is the leading open-source JavaScript library for mobile-friendly interactive maps.
Weighing just about <abbr title="33 KB gzipped &mdash; that's 123 KB minified and 218 KB in the source form, with 10 KB of CSS (2 KB gzipped) and 11 KB of images.">33 KB of JS</abbr>,
it&nbsp;has all the mapping <a href="#features">features</a> most developers ever need.</p>

<p>Leaflet is designed with <em>simplicity</em>, <em>performance</em> and <em>usability</em> in mind.
It works efficiently across all major desktop and mobile platforms,
can be extended with lots of <a href="plugins.html">plugins</a>,
has a beautiful, easy to use and <a title="Leaflet API reference" href="reference.html">well-documented API</a>
and a simple, readable&nbsp;<a title="Leaflet source code repository on GitHub" href="https://github.com/Leaflet/Leaflet">source code</a> that is a&nbsp;joy to
<a title="A guide to contributing to Leaflet" href="https://github.com/Leaflet/Leaflet/blob/master/CONTRIBUTING.md">contribute</a> to.</p>

<div id="map" class="map map-home" style="height: 300px; margin-top: 50px"></div>

<p>Here we create a map in the <code>'map'</code> div, add <abbr title="Here we use OpenStreetMap tiles, but Leaflet doesn't force you to &mdash; use whatever works for you, it's open source!">tiles of our choice</abbr>, and then add a marker with some text in a popup:</p>

<pre class="basic-code javascript"><code>var map = L.map('map').setView([51.505, -0.09], 13);

L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&amp;copy; &lt;a href="http://osm.org/copyright"&gt;OpenStreetMap&lt;/a&gt; contributors'
}).addTo(map);

L.marker([51.5, -0.09]).addTo(map)
    .bindPopup('A pretty CSS3 popup.&lt;br&gt; Easily customizable.')
    .openPopup();</code></pre>
