Is there a download function in jsFiddle, so you can download an HTML with the CSS, HTML and JS in one file, so you can run it without jsFiddle for debug purposes?
Adding /show does not present a pure source code, it's an embedded working example. To display it without any additional scripts, css and html, use:
http://fiddle.jshell.net//show/light/
