CSS中如何将li横向排列

直接贴段例子代码吧：

@{
Layout = null;
}

<!DOCTYPE html>
<style type="text/css">
.test li {
float: left;
width: 70px;
margin: 3px;
padding: 3px;
list-style-type: none;
display:inline;
}

</style>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Shared</title>
</head>
<body>
<div class="test" style="overflow:hidden;width:600px;height:45px; background-color:lightblue;margin-left: auto;margin-right: auto;">
<ul>
<li><a href="/Home/Index" style="text-decoration:none">首页</a></li>
<li><a href="/Home/News" style="text-decoration:none">新闻</a></li>
<li><a href="/Home/Prodects" style="text-decoration:none">军事</a></li>
<li><a href="#" style="text-decoration:none">科技</a></li>
<li><a href="#" style="text-decoration:none">体育</a></li>
<li><a href="#" style="text-decoration:none">联系</a></li>
</ul>
</div>
<div style="height:20px; width:1200px; background-color:green;margin-left: auto;margin-right: auto;">
</div>
<div class="main">
@RenderBody()
</div>
</body>
</html>
