Navigator: devicePosture property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

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

The Navigator.devicePosture read-only property returns the browser's DevicePosture object, which allows developers to query the device's current posture (that is, whether the viewport is in a flat or folded state) and run code in response to posture changes.

Value

A DevicePosture object.

Examples

js
const postureOutput = document.getElementById("currentPosture");

function reportPostureOutput() {
  // type property returns "continuous" or "folded"
  postureOutput.textContent = `Device posture: ${navigator.devicePosture.type}`;
}

navigator.devicePosture.addEventListener("change", reportPostureOutput);
