It's probably because your images are using the default display: inline property which applies line-height to the image, usually resulting in a bit of whitespace at the bottom of the image.
For some reason, the #btnWrapper div was forced to have a greater line-height than necessary in IE and FF. Adding a line-height of (at most) .7em proved to close up the white space (kind of funny because the actual buttons themselves (which are contained within the #btnWrapper div) are rendered with a line height of 1.3em, so this makes no real sense to me, but...).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
