... and while we're at it: Paul Annesley, another avid jQuery user, left an interesting Firefox extension link in an Ajaxian comment:
http://www.sitepoint.com/dustmeselectors/ Nice one to find unused css selectors. And being a validation fetishist, I would like to recommend this http://www.totalvalidator.com/ to anyone in search of a one-stop validation solution for both (X)HTML and WCAG. If you buy the full version, you'll also get screenshot service for those browsers you don't have available. I'm currently building a RIA using Zend Framework and jQuery, and it's a pain to make this work in IE6 and Opera, so these tools are helping me big time... Bernd
