Here there is NO meta viewport tag
Print viewport






For desktop;
Viewport (Firefox and other) = window.innerWidth/Height; (Includes scrollbar)
Viewport (IE) = document.documentElement.clientWidth/Height; (Does not include scrollbar)



For mobile devices;
Visual viewport (CSS pixels) = window.innerWidth/Height;
Layout viewport (CSS pixels) = document.documentElement.clientWidth/Height;
Device Width/Height (Device pixels) = screen.width/height;


Take me to page WITH meta viewport

Take me to CORRESPONDING (W/O META) V2 page (with SOME MORE CONTENT)
