IE8 and Below
 
The key to targeting Internet Explorer 8 and below, with a hack, is to append "9� to the end of your style. For example: 
 
body {
 color: red; /* all browsers, of course */
 color : green9; /* IE8 and below */
}
 
E7 and Below
 
we can use the * symbol to target IE7 and below, like so: 
 
body {
 color: red; /* all browsers, of course */
 color : green9; /* IE8 and below */
 *color : yellow; /* IE7 and below */
}
 
IE6
 
body {
 color: red; /* all browsers, of course */
 color : green9; /* IE8 and below */
 *color : yellow; /* IE7 and below */
 _color : orange; /* IE6 */
}
