Code:
<body id="top">

Code:
<a href="#top" onclick="scrollToTop();return false">Back to Top &uarr;</a>

Code:
function scrollToTop() {
    var position =
        document.body.scrollTop || document.documentElement.scrollTop;
    if (position) {
        window.scrollBy(0, -Math.max(1, Math.floor(position / 10)));
        scrollAnimation = setTimeout("scrollToTop()", 30);
    } else clearTimeout(scrollAnimation);
}

If you need a plain JavaScript function to add a smooth scrolling back to the top of the page, you can use this script.

Add an id of "top" to the <body> tag. Like this: <body id="top">
Add the onclick function to the link. Like this: <a href="#top" onclick="scrollToTop(); return false">Back to Top ↑</a>
Then either:
Include the JavaScript function in your markup, preferrably at the bottom before the closing </body> tag if possible.
Or, create a JavaScript file, place the script in it and call that file from your HTML document (either from the </head> section, or before the closing </body> tag if possible.)
Since this script is not part of the UI it can load last and will not negatively affect the user experience or usability of the page.
