li{float:left;margin-left:20px;}
p{float:left;}
#sports,#military,#bbs{display:none;}
</style>
<script type="text/javascript">
function tab(pid){
var ps = ['news','sports','military','bbs'];
for(var i=0,len=ps.length;i<len;i++){
if(ps[i] == pid){
document.getElementById(ps[i]).style.display = "block";
}else{
document.getElementById(ps[i]).style.display = "none";
}
}
}
</script>
</head>
<body>
