This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The DeviceOrientationEvent provides web developers with information from the physical orientation of the device running the web page.

Warning: Currently, Firefox and Chrome do not handle the coordinates the same way. Take care about this while using them.

Constructor

DeviceOrientationEvent.DeviceOrientation()
Creates a new DeviceOrientationEvent.
