Is there a way to frame a specific page element?

Is there a way to frame a specific page element?

So, I'm working on a web page, and I want to be able to let users give
feedback using google moderator. In order to help the user experience, I
want there to still be the logo and navigator bar across the top of the
page. The way I have it set up now is with frames. I have one frame on top
containing the logo and navigator bar, and the bottom frame being the
google moderator page. This is effective, but I would prefer it if there
wasn't that pesky grey navigation bar (the one with the links to search,
use youtube, etc.). I was poking around with the source-code and found
that if one where to go to
http://www.google.com/moderator/#16/e=1fe6a2/html/body/div[1]
you would have exclusively the navigation bar. Is there a way to link to
just the body? If not, is there a way to make a frame that excludes a
specific page element? If none of those would work, is there a way to crop
the top off? Any of the above options would be preferable over the current
layout. Any help is much appreciated. Thanks!
