Target IE9 Only via CSS

Question

Just wondering given these IE hacks in my bag of tricks

"\9" - for IE8 and below.
"*" - for IE7 and below.
"_" - for IE6.

i.e. such as

body { 
    border:2px solid blue;
    border:2px solid yellow \9;
    *border:2px solid green;
    _border:2px solid orange;
}

Whether anyone has such a hack for IE9 ? i.e. I'm trying to target IE9 only via CSS ?

Answer 1

Terrible, but it should work:

body { 
    border:2px solid blue;
    border:2px solid yellow \9;
    *border:2px solid green;
    _border:2px solid orange;
}
body:nth-child(n) {border:1px solid purple \9; /*Should target IE9 only - not fully tested.*/}
