I have recently uploaded my website. It looks great in firefox but in IE7 there are a few things not right. The website can be seen at www.winemax.ie. The problems in IE are that there is a white line along the right, and the boxes on the left that i have added have a gap along the bottom.

I installed the "Internet Explorer Stylesheet Over-rides" but then uninstalled it as there are meant to be some issues with the current version of Zen Cart which I am using, plus I don't know the code to change.

Is there any way I can fix these issues by just editing my CSS so that it looks the same in IE as it does in firefox. Thanks in advance.
