title: User generated custom css
body: <p>Hey, anyone have any idea what the best way to allow users to save custom css would be?  Specifically, there are about 4 color values that I would like to allow a user to choose and these colors would be used to create a custom theme for the user.  I'm thinking save values in the database and then using dom:loaded with prototype to set the custom style values but I'm wondering if theres a faster way?  Like dynamically creating css files or something?</p>
