Highlighting an active page

Hey! So I have a navigation bar and I want the active link to change colour when the user is browsing that page. So far I can only get the links to change colour when I hover over them and as I click them. What code do I need to include in my css to highlight the current page?

Any help would greatly be appreciated, thanks. 🙂

#access a:hover {
    color:#fff;
 }
#access a:active {
    color:#fff;
 }

<div id="access">
			<a href="http://www.buttoncombo.com/">Home</a>
			<a href="http://www.buttoncombo.com/?cat=5">360</a>
 			<a href="http://www.buttoncombo.com/?cat=18"> PS3</a>
 			<a href="http://www.buttoncombo.com/?cat=36"> Wii</a>
			<a href="http://www.buttoncombo.com/?cat=87"> 3DS</a>
			<a href="http://www.buttoncombo.com/?cat=69"> PSP</a>
			<a href="http://www.buttoncombo.com/?cat=39"> PC</a>
