CSS关于导航栏部分的代码：
/*------------------------------------------- Header-------------------------------------------*/#header { margin:40px 0 30px 0; }#nav {float:right;list-style:none;margin-top:15px;margin-right:0;margin-bottom:0;margin-left:0;}#nav li { display:inline; text-transform:uppercase; margin:0 0 0 35px; }#nav li a { background:url(../images/nav_sprite.png) no-repeat left 3px; color:#999; padding:0 0 0 14px; text-decoration:none; }#nav li a:hover,#header ul li a.selected { background-position:left -12px; color:#F9F9F9; }#header .main_logo { background:url('../images/logo_main.png') no-repeat bottom left; display:block; height:60px; text-indent:-9999px; width:500px; }/* Main Nav */#nav li.services a { background-position:left -27px; }#nav li.services a:hover,#nav li.services a.selected { background-position:left -42px; }#nav li.about-hba a { background-position:left -57px; }#nav li.about-hba a:hover,#nav li.about-hba a.selected { background-position:left -72px; }#nav li.news a { background-position:left -87px; }#nav li.news a:hover,#nav li.news a.selected { background-position:left -102px; }#nav li.contact a { background-position:left -117px; }#nav li.contact a:hover,#nav li.contact a.selected { background-position:left -132px; }
