HTML5现在本领太大了，PC端已经无法满足它的胃口了，它将强势攻入移动端，所以移动端中各种特效也得基于HTML5实现，看看我们将要介绍的slideout.js，能帮我们实现怎么样的侧边栏滑动特效呢~~

先看下运行效果：

一、准备资料

只需要准备slideout.js库即可：

https://github.com/Mango/slideout/blob/master/dist/slideout.js

小图标：

1）menu.png

2）happy.png

二、实现代码

HTML代码：

<!doctype html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"> 
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>适合移动手机的侧边栏滑动代码 - 站长素材</title>
<link rel="stylesheet" href="css/styles.css">
</head>
<body>
<nav id="menu" class="menu">
  <a href="#" target="_blank">
    <header class="menu-header">
      <span class="menu-header-title">主题</span>
    </header>
  </a>

  <section class="menu-section">
    <h3 class="menu-section-title">脚本代码</h3>
    <ul class="menu-section-list">
      <li><a href="#" target="_blank">jQuery</a></li>
      <li><a href="#" target="_blank">CSS3</a></li>
      <li><a href="#" target="_blank">HTML5</a></li>
      <li><a href="#" target="_blank">动画效果</a></li>
    </ul>
  </section>

  <section class="menu-section">
    <h3 class="menu-section-title">flash动画</h3>
    <ul class="menu-section-list">
      <li><a href="#" target="_blank">节日动画</a></li>
      <li><a href="#" target="_blank">flash植物</a></li>
      <li><a href="#">flash动物</a></li>
    </ul>
  </section>

  <section class="menu-section">
    <h3 class="menu-section-title">音效下载</h3>
    <ul class="menu-section-list">
      <li><a href="#" target="_blank">鸟叫声</a></li>
      <li><a href="#" target="_blank">狗叫声</a></li>
    </ul>
  </section>
</nav>
<main id="main" class="panel">
    <button class="btn-hamburger js-slideout-toggle">
      <span class="tooltip">点击打开</span>
    </button>
</main>

<script type="text/javascript" src="js/slideout.min.js"></script>
<script type="text/javascript">
    var slideout = new Slideout({
        'panel': document.getElementById('main'),
        'menu': document.getElementById('menu'),
        'padding': 256,
        'tolerance': 70
     });

     document.querySelector('.js-slideout-toggle').addEventListener('click', function() {
        slideout.toggle();
     });

     document.querySelector('.menu').addEventListener('click', function(eve) {
        if (eve.target.nodeName === 'A') { slideout.close(); }
     });

</script>

</body>
</html>

结构代码一项简单，主要注意一下slideout的用法，它传的几个参数：

panel：是指主要面板，指整个内容展示区域

menu：是指被隐藏的左侧菜单栏区域

padding：指点击按钮后，向右滑动的距离

CSS代码：

  }

  .btn-download {

  .btn-fork {

}

.menu,
.slideout-menu {
  position: fixed;

  z-index: 0;
  width: 256px;
  overflow-y: scroll;
  -webkit-overflow-scrolling: touch;
  display: none;
}

.panel,
.slideout-panel {
  position: relative;
  z-index: 1;
}

.slideout-open,
.slideout-open body {
  overflow: hidden;
}

.slideout-open .slideout-menu {
  display: block;
}

上面css代码可能有些有点多余，但是我们没必要care这么多细节呀，出来效果不就行了么~~
