我试图为手机创建一个左侧菜单，但我有一个问题：
当我滚动我的内容时，我的标题图像跟随滚动并隐藏了一些内容。我需要将标题修复到它的位置......
以下是我的问题的演示：http://jsfiddle.net/th46k/7/
我的 Html ：
<header id="top">
<span id="logo"><a href="index.php"><img src="http://placehold.it/350x150" /></a></span>
</header>
<div id="menu">
<ul>
<li><a href="#">Menu Item 1</a>
</li>
<li><a href="#">Menu Item 2</a>
</li>
<li><a href="#">Menu Item 3</a>
</li>
</ul>
</div>
<div id="right">
<div id="menubar">
<div id="button">Menu</div>
</div>
<p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.</p>
