[RESOLVED] Css text change colour on hover not working.

[n3wb]

nav li a
{
	display:block;
	text-decoration:none;
	color:#fff;
}
nav ul
{
	list-style: none;
	margin: 0px;
	padding: 0px;
}	
nav li
{
	padding: 5px 20px;
	text-align:center;
	float:left;
	background-color:#000;
	position:relative;
}	
nav li:hover{background-color:#fff; color:#000;}
					
nav li ul li
{
	float:none;
}
nav li ul
{
	position:absolute;
}

I've tryed doing
nav a:hover {color:#000;}

which works but only for when text is hovered, i want it to do it when the whole box is hovered over.
