手机做小项目，需要添加音乐，做此笔记，依赖jquery，代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style>
*{ margin:0; padding:0; }
/**
* 声音元件
*/
.z-hide{ display:none; }
.u-audio { position: absolute; top: 40px; right:20px; 132px; height: 73px; z-index: 200; }
.u-audio .btn_audio { 100%; padding-top: 29px; height: 44px; border:1px solid #eee; }
.u-audio .btn_audio .audio_open { display: inline-block; height: 44px; line-height: 44px; vertical-align: middle; background-color:#eee; cursor:pointer; position: absolute; bottom: 0; left: 56px; 44px; }
.u-audio.z-low { z-index: 1; }
</style>
</head>
<body>
<!-- 音乐 -->
<section class='u-audio f-hide' data-src='onlylove.mp3'>
<p class="btn_audio">

<span class='css_sprite01 audio_open'></span>
