Make a simple text link in the footer of your page smooth scroll the page back to an anchor at the top of the page.
This script is from Chris Coyer’s CSS Tricks website and originates from Karl Swedberg’s Learning JQuery website

Add an anchor with an id of ‘top’ in the header or somewhere at the top of the page…


<h4 id="top">Call today

…and the link on your ‘Back to Top’ text with the url of ‘#top’ to instantiate the scroll to the corresponding id on the same page…


<a href="#top">Back to Top</a>

…and here’s the code for your scripts.js file or similar…


// chris coyier's smooth Scrolling to an anchor on the same page

$(function() {

function filterPath(string) {
return string
.replace(/^\//,'')
.replace(/(index|default).[a-zA-Z]{3,4}$/,'')
.replace(/\/$/,'');
}

var locationPath = filterPath(location.pathname);
var scrollElem = scrollableElement('html', 'body');

// Any links with hash tags in them (can't do ^= because of fully qualified URL potential)
$('a[href*=#]').each(function() {

// Ensure it's a same-page link
var thisPath = filterPath(this.pathname) || locationPath;
if ( locationPath == thisPath
&& (location.hostname == this.hostname || !this.hostname)
&& this.hash.replace(/#/,'') ) {

// Ensure target exists
var $target = $(this.hash), target = this.hash;
if (target) {

// Find location of target
var targetOffset = $target.offset().top;
$(this).click(function(event) {

// Prevent jump-down
event.preventDefault();

// Animate to target
$(scrollElem).animate({scrollTop: targetOffset}, 400, function() {

// Set hash in URL after animation successful
location.hash = target;

});
});
}
}

});

// Use the first element that is "scrollable" (cross-browser fix?)
function scrollableElement(els) {
for (var i = 0, argLength = arguments.length; i
var el = arguments[i],
$scrollElement = $(el);
