Your sites may have different issues at various screen resolutions because they don't look the same on a laptop, an iPhone, a Kindle Fire, or a Galaxy Note.

Now, you may emulate many common devices while testing your website's accessibility at various resolutions. Simply select the device you want to use for your tests, or use 800x600 by default.

Accessibility reports will be run in a browser utilizing the user agent string of the chosen device, along with its viewport's width, height, and device scale factor.
