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.
