adding custom css for a page

I would like to add the following css and only have it work on pages:

#navlist{position:relative;}
#navlist li{margin:0;padding:0;list-style:none;position:absolute;top:0;}
#navlist li, #navlist a{height:44px;display:block;}

#home{left:0px;width:46px;}
#home{background:url('img_navsprites.gif') 0 0;}

#prev{left:63px;width:43px;}
#prev{background:url('img_navsprites.gif') -47px 0;}

#next{left:129px;width:43px;}
#next{background:url('img_navsprites.gif') -91px 0;} 

#home a:hover{background: url('img_navsprites_hover.gif') 0 -45px;}
#prev a:hover{background: url('img_navsprites_hover.gif') -47px -45px;}
#next a:hover{background: url('img_navsprites_hover.gif') -91px -45px;}

Any help on how I should format it and add it to the 2011 Style CSS would be appreciated. Many thanks in advance,
