Hello, I am trying to figure out the best (simplest) way to offer customized look and feel of a MVC website. I am using Spring DI, Spring MVC, jQuery and JSP pages. I need the ability to change the colors (CSS) and images (img src) based upon a customers login.

I am not sure how the best way to approach this is. I hate to duplicate CSS and go that route. I was hoping Sitemesh or Velocity may offer something like that, but I haven't spent much time with those technologies.

Thanks
