This came up on discussion over on openguides-oxford. We'd like to be
able to put a distinctive style on pages for places that have now
closed. Rather than hardcoding this for a "Closed" or "Now Closed"
category, Dom and I thought a better solution would be to simply add
classes for all categories and locales that a page is in.
So for example,
would have HTML:
<div id="content" class="cat:baby_changing_facilities cat:free_wifi
cat:restaurants cat:wifi loc:park_end_street loc:west_central">
rather than the simple <div id="content"> that's currently there.
