Target IE9 or IE8 but not both using CSS

Question

I know it shouldn\'t be done, but I just want a quick fix for now and that will give me time to find a proper fix for this.

How can I target IE8 alone using CSS bec

Answer 1

This should work only in IE9 (and probably newer versions as well):

:root #element-id {
  margin: 400px\9;
}

It is because :root pseudo class is not implemented in versions prior to IE9 (see http://msdn.microsoft.com/en-us/library/cc351024%28v=vs.85%29.aspx).
