CSS Hacks for IE

The following are a few techniques you can use to target specific IE versions via CSS markup.

TAGIDENTIFIER {
    property:  valueA;   /* all browsers, of course */
    property:  valueB\9; /* IE9 and below, the 9 has nothing to do with the version in place */
    *property: valueC;   /* IE7 and below */
    _property: valueD;   /* IE6 */
}

/* IE6 ONLY */
    * html TAGIDENTIFIER

/* IE7 ONLY */
    *:first-child+html TAGIDENTIFIER

/* Modern Browsers & IE7+ */
    html>body TAGIDENTIFIER

I would like to point out that using IE conditional comments is still the best way to address specific browsers, it's just worthwhile to know about these techniques.
