Lightweight jQuery extension for modifying scrolling speed in modern web browsers. Supports vertical or horizontal scrolling direction, including user-defined easing.


Include the latest version of jQuery and jQuery.scrollSpeed.js in the <head> of your HTML document:

<script src="jQuery.min.js"></script>  
<script src="jQuery.scrollSpeed.js"></script>

How to Use

Reference the scrollSpeed() method and modify the step and speed parameters to create the desired scrolling effect. The step parameter defaults to 100 units, while speed defaults to 800 milliseconds; custom easing is optional. See the live demo: code.nath.co/scrollSpeed

$(function() {  

    // Default
    jQuery.scrollSpeed(100, 800);
    // Custom Easing
    jQuery.scrollSpeed(100, 800, 'easeOutCubic');
