Most people rely on window.innerWidth, document.documentElement.clientWidth, or $(window).width() which do not always accurately report the viewport width used in CSS media queries. For example, WebKit browsers change the size of their CSS viewport when scroll bars are visible, while most other browsers do not. Since window.innerWidth remains constant regardless of the scroll bar state, it is not a good option for use with Chrome or Safari. Additionally, Internet Explorer 6, 7, and 8 do not support window.innerWidth. On the other hand, document.documentElement.clientWidth changes based on the scroll bar state and therefore is not a good option for Internet Explorer, Firefox, or Opera.
