Disclaimer:
This is definitely me being partisan here. Hopefully the matter is sufficiently close to relevant (with this being a web site and all) for you to forgive me for this indulgence.
I've just been testing the latest article on Internet Explorer. I use Firefox myself, both on Windoze and Linux. There are some oddities in IE where it incorrectly interprets things like widths and margins. This is quite evident if you look at the second photo in the new Mazzer Mini E review.
I thought about bodging the style sheet but I can't be bothered.
Firm recommendation: for the site to look its best (and as intended) you need to use a Gecko-based browser such as Firefox.
