Here is a function to return you the width the browser is using for media queries. For some reason, it is a bit different in each browser.
View gist:4962688
function getWindowMediaWidth() {
if(!window.matchMedia){
// it should be this, so return it when we can't
// figure it out. Of course, it does not do a lot
// of good if the browser does not support media
// queries.
return document.body.clientWidth;
}
You can’t perform that action at this time.
