Device emulators and simulators enable you to mimic your development site on a range of devices, from your workstation.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.
