手写侧边超炫工具栏

先来张效果图：

如下为核心代码：

-- index.htm

<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8" />
<title>Document</title>
<link rel="stylesheet" href="css/index.css" />
</head>
<body>

<div class="toolbar">
    <a href="javascript:;" class="toolbar-item toolbar-item-weixin">
        <span class="toolbar-layer"></span>
    </a>
    <a href="javascript:;" class="toolbar-item toolbar-item-feedback"></a>
    <a href="javascript:;" class="toolbar-item toolbar-item-app">
        <span class="toolbar-layer"></span>
    </a>
    <a href="javascript:;" class="toolbar-item toolbar-item-top"></a>
</div>

</body>
</html>
