This reminded me, when in the beginning of my career in the mid 2000s I spent hours trying to figure out why some css did not seem to get applied in IE6 (Well trying to figure out why x didn't work in IE6 was what people were doing 30%+ of their time in web application development back then) In this case it turned out to be that I was using "grey" for a color which worked perfectly fine in Firefox, but Internet Explorer only knew about the US spelling "gray" so it just ignored my declarations. I haven't used css color names since.
