[Zope] Plone is neglecting my styles

[Mitch Pirtle]

Hi all,

In working with Plone, I'm currently in the throes of creating the
template for a portal.  The default skin in Plone has a white body, but
my ploneCustom.css specifically sets it to grey.

But when I view the page rendered by Plone, the background is stil
white.  ?

But wait, there's more - some of the other styles get applied, but not
all.  Does Plone's stylesheets have the css equivalent of 'reserved
words' or what?
