Floating Back to Top Button in the Corner

floating-back-to-top-button.html

// Add an anchor link somewhere in your HTML page, by adding a unique class name. 
// Preferably add it somewhere outside from any containers, so we can add the fixed position to our floating back to top button.

<a href="#" class="back-to-top">Back to Top</a>
  
// OR, if you don't have access to html source you can create the link using some jQuery. 
// Make sure to add the script below above the ending of </body> tag.
// Don't forget to get jQuery library files and add it above the ending tag of </head>.  

<script type="text/javascript">
	$('body').prepend('<a href="#" class="back-to-top">Back to Top</a>');
</script>

script.js

// The jQuery
// Remember that the back to top button has "display: none;" in CSS, to hide it when the page loads. 
// So, to make it visible when you scroll the page down when need to check, using jQuery, after how many pixels the back to top button should appear. 
// To do that we need a scroll() function event and an if statement to check the amount scrolled down.

var amountScrolled = 300;

$(window).scroll(function() {
	if ( $(window).scrollTop() > amountScrolled ) {
		$('a.back-to-top').fadeIn('slow');
	} else {
		$('a.back-to-top').fadeOut('slow');
	}
});

// The Animated Effect
// Now that we have our back to top button in place, we need to add the jQuery animation effect when the page is returning to top. 
// This must be added on a click event, so when the button is clicked, code should be triggered.

$('a.back-to-top').click(function() {
	$('html, body').animate({
		scrollTop: 0
	}, 700);
	return false;
});

style.css

a.back-to-top {
	display: none;
	width: 60px;
	height: 60px;
	text-indent: -9999px;
	position: fixed;
	z-index: 999;
	right: 20px;
	bottom: 20px;
	background: #27AE61 url("up-arrow.png") no-repeat center 43%;
	-webkit-border-radius: 30px;
	-moz-border-radius: 30px;
	border-radius: 30px;
}
