# Device emulators and simulatorsĭevice simulators and emulators simulate not just the browser environment but the entire device. Since Edge does not ship with legacy compatibility, use IE 11's Emulation to simulate how your page would look in older versions of Internet Explorer. To emulate Windows Phones, use Microsoft Edge's built-in emulation. # Firefox' Responsive Design Viewįirefox has a responsive design view that encourages you to stop thinking in terms of specific devices and instead explore how your design changes at common screen sizes or your own size by dragging the edges. Test your site on browsers running on real devices to be certain everything behaves as expected.

Cloud-based emulators let you automate unit tests for your site across different platforms.īrowser emulators are great for testing a site's responsiveness, but they don't emulate differences in API, CSS support, and certain behaviors that you'd see on a mobile browser.

Device emulators and simulators let you 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 like iPhones, we encourage you to check out other browsers solutions for emulation. Your job doesn't end with ensuring your site runs great across Chrome and Android.
