<p id="shortdesc">Uses an overlay to create a popup.</p>
<div id="docs">
<p>
Click on the map to get a popup. The popup is composed of a few basic elements: a container, a close button, a place for the content, and an element to represent the little arrow at the bottom. To anchor the popup to the map, an <code>ol.Overlay</code> is created with the popup container. A listener is registered for the map's <code>click</code> event to render the popup, and another listener is set as the <code>click</code> handler for the close button to hide the popup.
</p>
<p>
See the <a href="popup.js" target="_blank">popup.js source</a> to see how this is done.
