Then for example, if on next week's edition of our shopping list we begin to loose all hope of
finding these items locally, we could change the background color for all items of class "no" to
be gray. (We could even change their "Visibility" to be "hidden".) Such changes would leave
more confusion in their wake if the class name simply echoed an initial description of how to
display the element (e.g. "cheese-yellow-orange") rather than gave a semantic hint.
