CSS namespaces

[Norbert Hartl]

While testing how hard it will be to bring my site
into pier I discovered some css class clashes. For
people it is quite normal to assign classes like 
header, footer and the like.

In my opinion a cms like pier should try to step
out of the way of any usage conflict. Therefor I
would propose to namespace the css classes. A
pr_header, pr_footer will do I think.

Or do I missunderstand something completely? For me
it was not possible to reconstruct our layout without
haveing to remove all librares for the application. But 
then it is tedious to work with pier as the edit boxes
and stuff are too small.

What is the best approach to bring in the own developed
design and having pier still functioning?

thanks,

Norbert
