[Plone-UI] Page borders and backgrounds

[Rick Wheatley]

Hello -

I'm trying to create a page with these characteristics:

- a hairline on the left and right border.
- white in the page space and another color outside the right and  
left border

This is something that many mamba based pages seem to do and I wonder  
if its possible in plone.

Its almost a bit of a floating effect where there is sometimes even a  
shadow around the page area.

I hope this makes sense..
