Alright, so I have an UL with 8 list items in it that are displayed inline. Each item is a 50×50 image. Everything is fine and dandy in Firefox, but in IE7 the last list item jumps down a line and is underneath the first list item.
In IE7 the borders of the images are thicker than the ones in Firefox. When I changed the right padding from 8.5 (I don’t know why I had this as a decimal in the first place) to 7, the images lined up correctly in IE and just moved a little to the left in Firefox.
