Customizing content?

Hey folks,

I have a couple of wordpress pages/posts that will need some additional styles/layout added to the content. It would be easy for me to go in and add some divs with id’s around the content in the WP editor. However, I doubt that my user will be able to do this.

Right now, in the WP editor, under format, there are only basic tag options (h1, p etc.) Is there a way to add an option for div and perhaps a predefined class?

Or is there another solution?
