Extra space before posts?

I take it you fixed it?

What browser are you using? I’m still not seeing any spaces.

Ok, for future reference, let us know what you’re using. It works in IE7 and Firefox, but not in IE6.
You have your doctype set to XHTML 1.0 Strict, but your code doesn’t conform to those standards. I’d recommend changing the doctype to transitional or something that fits, or else correcting the errors. http://validator.w3.org/check?verbose=1&uri=http%3A%2F%2Fandria-and-co.com%2F is a good resource.
