nanoScroller.js is a jQuery plugin that offers a simplistic way of implementing Lion-styled scrollbars for your website. It uses minimal HTML markup being .nano > .content. The other scrollbar div elements .pane > .slider are added during run time to prevent clutter in templating. The latest version utilizes native scrolling and works with the iPad, iPhone, and some Android Tablets.
