--- layout: example.html title: Popup shortdesc: Uses an overlay to create a popup. docs: >
Click on the map to get a popup. The popup is composed of a few basic elements: a container, a close button, and a place for the content. To anchor the popup to the map, an ol/Overlay
is created with the popup container. A listener is registered for the map's click
event to display the popup, and another listener is set as the click
handler for the close button to hide the popup.
