Yikes! Just looked at the source and realized the site is at best xhtml 1.0 transitional. Me bad.

Just so use to everyone using full xhtml that I got used to expecting it. :/
The container would've been the div that contained the content (a wrapper is a div that's used to wrap around the container div for alignment purposes). A standard web page would have 4 div containers (banner, left nav panel, main panel, and footer) within xhtml strict.
Part of the problem I see now is that page has no DTD listing like this....
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
which forces IE into quirks mode and fouls it up, even w3c's validator completely balks at it.

[Check your code against the validator. HTML-Tidy is even stricter if you really want to scrub your site for increased SEO]
Another thing -- there is no cellpadding, which is why the text is right against the TABLE's edge.
Are you comfortable with working with xhtml? The reason I ask is, the code is simple enough to convert over to divs only, and ditch the tables (which shouldn't be used for layout. W3C is laying that down hard -- tables are to be used only for tabular data, not aligning images or text). Divs really speed up page loads, and why they're becoming quite popular, too.
Once you work in xhtml strict/css, you don't ever want to return to html again. Just plain easier to design pages with.
