div classes when using browser-based editing tool

[Bob Raiselis]

I'm trying to sort out how to let editors specify classes for divs  
(so that they can put text into a box with a colored background, for  
instance) when using the browser-based editing tool. All of the < and  
 > characters get neutered, of course. Switching to HTML editing mode  
works, of course, but it's too difficult for some editors to make  
sense of what to change there.

I want editors to be able to type in <div class="greenbox">Here's my  
text</div> and have that work when they are using the built-in  
editor. I would set up a .greenbox class in the CSS configuration.

Am I missing a setting somewhere that I should change?

thanks

Bob
