Moving a finished and cut CSS design from one platform to another requires wit, great motor-skills, some Ro-gain, and rewriting a bit of the CSS that so intimately put together to make the previous platform project the glory of the design onto the world. But rewriting the CSS means that there are going to be poor little orphaned classes and IDs (which translates into classes and IDs which aren't used anymore) trapped inside my CSS documents. Having them be prisoners was not an option I wanted to live with (and then of course they take up some space, modem users in mind).
With my humble companion FireFox I sought out the great Google to aid me in the quest to free these orphans from their cascading cages, and it wasn't in vain - I found a great FireFox addon from the Sitepoint website called Dust-Me Selectors that, once you activate it, keeps a record of all the unused selectors in your style-sheets.
"But some selectors are only used on certain pages," I hear you cry in disbelief. Just activate the addon and surf around your site until you've singled out the selectors that aren't used on any of the pages.
Head over to Sitepoint and get Dust-Me Selectors now!
Cheers,
