Please, see at this address:

I’ve 2 problems with IE6.
1. navigation bar at right has a dark gray background:
however, it doesn’t arrive to the footer, but stops a little
after the text, so it is possible to see the black #container.
Morevoer, the border-top line of the footer appers not
at he top of the footer, but of the bottom of navigation bar.
2. in #content, the text arrives at the end of #content
while other browsers leave a bit of space.
