<ul id="nav">
  <li class="current"><a href="#examples">examples</a></li>
  <li><a href="#section-1">Section 1</a></li>
  <li><a href="#section-2">Section 2</a></li>
  <li><a href="#section-3">Section 3</a></li>
</ul>
<div id="container">
  <div class="section-wrapper" id="examples">
    <div class="section">
      <h2>Examples</h2>
      <p><a href="index2.html">垂直位置导航</a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<a href="index.html">水平位置导航</a></p>
    </div>
  </div>
  <div class="section-wrapper" id="section-1">
    <div class="section">
      <h1>Horizontal Nav</h1>
      <p>To account for the offset of the horizontal nav, add top negative margin and top padding. For example, the navigation on this page is 50px tall. So to each section, add a -50px top margin and 50px to offset the height of the nav. That means when you go to each section, it will scroll to the exact top of the section while accounting for the height of the nav.</p>
    </div>
  </div>
  <div class="section-wrapper" id="section-2">
    <div class="section">
      <h2>Section 2</h2>
