Hacks

IE-6 ONLY

* html #div { 
    height: 300px;
}

IE-7 ONLY

*+html #div { 
    height: 300px;
}

IE-8 ONLY

#div {
  height: 300px\0/;
}

IE-7 & IE-8

#div {
  height: 300px\9;
}

NON IE-7 ONLY:

#div {
   _height: 300px;
}

Hide from IE 6 and LOWER:

#div {
   height/**/: 300px;
}

html > body #div {
      height: 300px;
}
