This seems to be a perfect way to target IE8. Anything I'm overlooking here?

#onoff li+li+li a {
float:left; /* Target IE8 */
margin-right:-14px; /* Target IE8 */
}
#onoff li:nth-child(2) a, #onoff li:nth-child(3) a {
position:absolute; /* Cancel target IE8 */
z-index:1;
color:green;
font-weight:bold;
margin:0; /* Cancel target IE8 */
}
