I havent been posting lately bc I have been knee deep in theme hell. It is coming along… I spent over 3 hours the other day trying to skin the damn date picker calendar pop up, all to no avail. I finally found a way to do it. I created an alt style sheet, saved it to my style library, and copied all the date picker styles that i wrote to it and applied the alt stylesheet via the master page alt style sheet field (site/_Layouts/ChangeSiteMasterPage.aspx). It works 🙂 One caveat: you only get one date picker style for your site collection-if you apply a different theme to a subsite, the date picker will still pick up the style from the alt stylesheet.
