I've seen lots of similar problems, but not quite this one. This page, http://natrlobs.sc22.info/
displays fine in Firefox, of course. In IE, I have forced it to display correctly by adding a conditional comment with an extra closing div tag below the closing tag for the right column div.
</div><!--close column right-->
But as far as I can find, there is no such conditional comment for targeting Chrome or Safari, both of which have this same problem. So in both browsers, the central light-coloured div, "container_12" appears shortened, and the footer div appears to crowd into the right column div.
One little extra </div> will fix the whole page in IE, Chrome, and Safari...but alas, will break it in Firefox.
What else can I do? Is there a problem with my doctype, which is
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html dir="LTR" lang="en">
<html dir="LTR" lang="en">
I'm doing all this in OSCommerce, using a template based on the "rock solid" 960 grid system, FWIW.
Thanks for any help!
