cssSandpaper – a CSS3 JavaScript Library

The cssSandpaper JavaScript library looks at the stylesheets in an HTML document and, where possible, smooths out the browser differences between CSS3 properties like transform, opacity, box-shadow and others.  This script is not only useful for developers who want to support CSS3 in IE (which doesn’t support it in IE natively) but in other browsers which implement their own vendor-specific variants of these properties.
