IE6 Only
==================
*html or { _property:... }

IE7 Only
==================
*+html or { *property:... } - Keep in mind that you have to put the IE7 property first within the same selector.

IE8 and IE9 (There doesn't seem to be an 'IE8 Only' hack)
==================
Use \9 = p { color:#f00\9; } - http://stackoverflow.com/questions/660652/ie8-css-selector
The above solution doesn't work with font-family, so instead you need to use "\0/ !important" >> { font-family:Arial \0/ !important; }

==================
:root .class/#id { property:value \0/IE9; }

IE10 Only
http://css-tricks.com/ie-10-specific-styles/
==================
Use this JavaScript: 
var doc = document.documentElement;
doc.setAttribute('data-useragent', navigator.userAgent);

Then use this CSS:
html[data-useragent*='MSIE 10.0'] h1 { color: blue; }

IE10 and IE11
==================
@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
	.selector { property:value; }
}
