OpenLayers v4.0.1 API - Class: FullScreen

# Class: FullScreen

This documentation is for OpenLayers v4.0.1. The latest is v.

## ol.control.FullScreen

Provides a button that when clicked fills up the full screen with the map. The full screen source element is by default the element containing the map viewport unless overriden by providing the `source` option. In which case, the dom element introduced using this parameter will be displayed in full screen.

When in full screen mode, a close button is shown to exit full screen mode. The Fullscreen API is used to toggle the map in full screen mode.
