Internet Explorer 6 and below had a problem with the !important identifier that caused it to be ignored if another declaration of the same property appeared later in the same style declaration block. This can be used to feed Internet Explorer 6 and below special property values that are ignored by other browsers. Internet Explorer 7 fixed this issue.
