Question

我试图让我的网站导航栏与标题图像一起滚动到页面顶部。到目前为止，我的代码是：

<html>
<head>
<link href="C:\Users\Karl\Desktop\New Bistro\menu_assets\styles.css" rel="stylesheet" type="text/css">
<style>
.header{
 height:70%;
 background-image:url('http://s22.postimg.org/4eags0oep/header.png');
 background-size: cover;
 width:100%;
}
.nav{
 height:8%;
 width:100%;
}
.body{
 height:100%;
 background-image:url('http://upload.wikimedia.org/wikipedia/commons/6/60/Solna_Brick_wall_Silesian_bond_variation1.jpg');
}
.logo {
 background-image:url('Title.png');
 margin-left:auto;
 margin-right:auto;
 height:140px;
 width:554px;
 right:35%;
 position:fixed;  
 z-index:9999 
}
</style>
</head>
<body background="http://htmlgiant.com/wp-content/uploads/2010/09/A-grey.jpeg" style="margin: 0; padding: 0;">

<div class="header">
<a href="#Home"><div class="logo"></div></a>
</div>

<div class="nav">
<div id='cssmenu'>
<ul>
   <li><a href='http://www.132glenbistro.com/'><span>Home</span></a></li>
   <li><a href='http://www.132glenbistro.com/'><span>Menu</span></a></li>
   <li><a href='http://www.132glenbistro.com/'><span>Gallery</span></a></li>
   <li class='last'><a href='http://www.132glenbistro.com/'><span>Contact</span></a></li>
</ul>
</div>
</div>

<div class="body">
<div align="center">
<table width="70%" style="height: 200%;" cellpadding="10" cellspacing="0" border="1">
<tr>
<td colspan="2" style="height: 100px;" bgcolor="#ffffff">

</div>
</div>

</body>

我尝试使用javascript来做到这一点无济于事。我是javascript编程的新手一般都会感激任何帮助。

Bootstrap提供了名为“Affix”的功能。即使你只使用这个方面，我认为使用Bootstrap比尝试自己做更有益。或者您可以查看来源以了解他们是如何做到的。

无论如何，如果没有看到你的尝试，我看不出我们应该如何帮助你。
