slimScroll is a small jQuery plugin that transforms any div into a scrollable area with a nice scrollbar - similar to the one Facebook and Google started using in their products recently.
slimScroll doesn't occupy any visual space as it only appears on a user initiated mouse-over. User can drag the scrollbar or use mouse-wheel to change the scroll value.
nanoScroller.js is a jQuery plugin that offers a simplistic way of implementing Mac OS X 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.
iScroll 4 is a complete rewrite of the original iScroll code. The script development began because mobile webkit (on iPhone, iPad, Android) does not provide a native way to scroll content inside a fixed width/height element. This unfortunate situation prevents any web-app to have a position:absolute header and/or footer and a scrolling central area for contents.
jScrollPane is a cross-browser jQuery plugin which converts a browser's default scrollbars (on elements with a relevant overflow property) into an HTML structure which can be easily skinned with CSS.
