i am making a menu for my school assignment and it needs to work in both IE and firefox.
I am done the menu and it works perfectly in firefox, but i am having trouble getting it to display properly in IE

A part can be found over here: <http://tutudragon3.info/ie-trying.php>

When i click the home image in firefox, a dropdown sort of thing pops-up with 2 images with text "d" and "d". In firefox, there is no space between those dropdown images, but when i try it in IE, I see a small blank space between them.

how could i fix this (delete that space) please. I tried many different things but it didn't work.

Using IE8 by the way.
