* { 
margin: 0; 
padding: 0; 
font-family: "Microsoft Yahei","Arial"

.navigator { 
width: 180px; 
display: block; 
margin-top: 30px; 
margin-left: 30px; 
border-top: 10px solid #ddd; 
border-bottom: 10px solid #ddd; 
border-left: 3px solid #ddd;

.tabs { 
list-style: none; 

} 

.tabs li { 
clear: both; 
overflow: auto; 
} 

.tabs li h3 { 
padding: 0; 
margin:0; 
font-size: 14px; 
height: 40px; 
line-height: 40px; 
text-align: center; 
width: 180px; 
cursor: pointer; 
background: #07f; 
color: #fff; 
border-bottom: 1px solid #ccc; 
} 
.tabs li:last-child h3 { 
border:none; 
} 
.tabs li h3.current { 
background: #6af;

$(document).ready(function(){ 
$(".nav1").css("height","160px"); 
$(".tabs li h3:first").addClass("current"); 
$(".tabs li h3").click(function() { 
$(".tabs li h3").removeClass("current"); 
$(this).addClass("current"); 
$(".tabs li ul").animate({height:"0"},"fast"); 
$(this).next().animate({height:"160"},"slow"); 
}); 
});
