ScrollUp 
A jQuery plugin to create a customisable 'Scroll to top' feature that will work with any website
Installing with Bower
To install scrollUp with Bower:
bower install scrollup
How to use
Simply include the jquery.scrollUp.min.js file and place the following in the head of your document (make sure jQuery is included):
Minimum setup
$(function () {
$.scrollUp();
});
Example with default options
$(function () {
$.scrollUp({
scrollName: 'scrollUp', // Element ID
scrollDistance: 300, // Distance from top/bottom before showing element (px)
scrollFrom: 'top', // 'top' or 'bottom'
scrollSpeed: 300, // Speed back to top (ms)
easingType: 'linear', // Scroll to top easing (see http://easings.net/)
animation: 'fade', // Fade, slide, none
animationSpeed: 200, // Animation speed (ms)
scrollTrigger: false, // Set a custom triggering element. Can be an HTML string or jQuery object
scrollTarget: false, // Set a custom target element for scrolling to. Can be element or number
scrollText: 'Scroll to top', // Text for element, can contain HTML
scrollTitle: false, // Set a custom <a> title if required.
scrollImg: false, // Set true to use image
activeOverlay: false, // Set CSS color to display scrollUp active point, e.g '#00FFFF'
zIndex: 2147483647 // Z-Index for the overlay
});
});
activeOverlay
To create a visible line to help determine an ideal scroll distance from the top, assign a valid CSS colour to the activeOverlay setting. This could be HEX, HSLA or RGB(A). Example: activeOverlay: '#00FFFF'. See the demo for an example.
scrollFrom
New feature in v2.0.0. Display the scrollUp element either the set distance from the top (default), or from the bottom of the page.
Destroy method
New feature in v2.0.0. If you need to destroy the instance of scrollUp, simple use the following to remove all modifications to the DOM:
$.scrollUp.destroy();
Fully Customizable
ScrollUp is fully customisable via CSS which makes it simple to fit right into your project. Simply target the scrollUp's generated ID in your CSS file and set your styles. Below is a basic style example:
#scrollUp {
bottom: 20px;
right: 20px;
padding: 10px 20px;
background-color: #555;
color: #fff;
}
Use background image
To use a background image instead of text, simply set scrollImg: true. This will allow you to set a background image in your CSS file.

Leave anchor title for ScrollUp as scrollText by default, but allow it to be changed in instances where anchor title and scrollText should be different, for instance when using ↑ symbol (↑) as scrollText a separate title is needed otherwise it reads as '↑'.
