Sorry, but that sounds ridiculous. You're saying "they" can change the
entire page but not one element there. Should I offer my services to "them"?
For some indecent sum of money, I could do the impossible for them (creating
a copy, changing what needs to be changed, and uploading the modified
version "at a blunt whole-page level").

CSS works with a cascade, that's certain, but we _always_ have that problem
with CSS.

Yet you postulate the addition of a class attribute, thereby changing their
HTML:

> <div class="hideable" >

If you can actually modify the HTML, you can do things much more easily and
naturally.
