 Viewport
 ===================================
-Browser tests in Splunk Synthetic Monitoring capture the visual experience of a user interacting with your application. The viewport is the framed area on a device's screen for viewing information, such as the browser window on a desktop. By default, Browser tests run from a desktop-sized viewport. You can configure tests to run from other viewport sizes to test the user experience from a variety of window sizes and device types.

-When you set up a test, you can choose the viewport size from a list of common devices, or set a custom viewport by height and width.
