title: Disable Safari 5's “overscroll” behaviour using CSS or JavaScript
body: <p>Safari 5 on OS X Lion allows you to scroll past the visible bounds of the page, revealing a linen texture beneath it. It's a nice effect, but for some web apps – particularly those with fixed-position elements like a sidebar – it can be distracting. Does anyone know how to disable the effect using CSS or JavaScript? It must be possible, because some sites like Apple's own <a href="http://icloud.com" rel="noreferrer">iCloud</a> have done so.</p>
