Scroll page to a certain pos

scrollTo.js

//Since in Chrome, document.body.scrollTop reflects the  scroll distance,
//while in IE9 and Firefox, document.documentElement.scrollTop does.
//So this will work in either of the 3 browsers to scroll to the pos you want.
function scrollTo(pos) {
	if(document.body.scrollTop){
		document.body.scrollTop = pos;
	} else if(document.documentElement.scrollTop){
		document.documentElement.scrollTop = pos;
	} else {
		document.body.scrollTop = document.documentElement.scrollTop = pos;
	}
}
