Smooth scroll

This code sample will allow you to scroll the view to a predefined vertical offset (in pixels) or the beginning of a specified id.

function smoothScroll(y) {
	if (typeof y === "string") {y=document.querySelector("#"+y);}
	if(typeof y === "object") {y=y.offsetTop;}
	for (var i = 0; i < y; i++) {
        setTimeout(function () {
            document.body.scrollTop = arguments[0] * 2;
        }, i * 2, i);
    }
}

Directions:
- Call smoothScroll(y);
- y can be a number (offset from top in pixels) or a string identifying an id.
