VisualViewport class

The interface of the Visual Viewport API represents the visual viewport for a given window. For a page containing iframes, each iframe, as well as the containing page, will have a unique window object. Each window on a page will have a unique representing the properties associated with that window. You can get a window's visual viewport using Window.visualViewport.

Note: Only the top-level window has a visual viewport that's distinct from the layout viewport. Therefore, it's generally only the object of the top-level window that's useful. For an <iframe>, visual viewport metrics like VisualViewport.width always correspond to layout viewport metrics like document.documentElement.clientWidth.
