Test your site on browsers running on real devices, to be certain everything behaves as expected. But a browser emulator doesn't emulate differences in API, CSS support, and certain behaviors that manifest only on a mobile browser on an actual device.
When you don't have a particular device, or want to do a spot check on something, the best option is to emulate the device right inside your browser.Even though Device Mode can simulate a range of other devices such as smart phones, we encourage you to check out solutions for emulation provided by other browsers.
Your job doesn't end with making sure your site runs great across Microsoft Edge and Android.
