Okay can someone explain to me what these codes do,
Code:
#nav_left{ 
	float:left;
	width:260px;
	background-color: orange;
	color: white; 
	min-height:650px; /* for modern browsers */
	height: auto !important; /* for modern browsers */
	height:1200px; /* for IE5.x and IE6 */
}
So what is these codes below mean?
Code:
height: auto !important;
Thank you very much in advanced.
