Again, there's no need to fret over 2^N classes, because you can assign 
more than one class to an object.  You handle the overlapping of classes on 
the HTML/DOM side, not the CSS side.

In the case of overlapping state pairs such as Enabled/Disabled and 
Selected/Deselected, all you need minimally are:

- one default style that combines all the "off" states
- one style for each "on" state

For state-pairs, this is N+1, not 2^N.

If you want to throw tristates and other multiple-state groups into the 
mix, the formula clarifies to:

         classes needed = total_states - total_state_groups + 1

Cheers,
Paul
