CSS Hover Change Background...

[Winterworks]

A part of my .css file is this...

.navigation_text {
	margin-left: 43px; 
	width:155px; 
	height:48px;
	text-decoration: none;
	font-size: 12px;
	color: #000000;
	background: #F8F8FF no-repeat top left; 
	
}

Here's the code to match it in my index.html...

<div class="navigation_text"><strong>Website Homepage:</strong><br />Click <a href="http://www.website.com/index.html">here</a> to view our<br />homepage.</div>

Right now, on the site, the <div> box has a background color of #F8F8FF, which is exactly what I want. But I want it so when you put your mouse over it, the background of the whole box changes. I want it to change to white.

Not the links, or text, but background...

Yes, I'm just learning CSS.
