做好如图所示：
下面开始上代码：
html代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" href="css/music.css">
</head>
<body>
<audio src="" id="mymusic"></audio>
<div class="music">
<div class="pic_div"> <img src="images/music/pictures/disc.png" alt="" class="disc"> <img src="images/music/pictures/default.jpg" alt="" id="music_pic"> <span class="dot"></span>
<div class="music_program">
<div id="prograss"></div>
</div>
<div class="time">
<p><span id="currenttime">0:00</span><span>/</span><span id="duration">0:00</span></p>
</div>
<div class="music_menu"> <span onClick="backMusic()"></span> <span onClick="playPause()" id="playbtn"></span> <span onClick="nextMusic()"></span> </div>
</div>
</div>
</body>
<script src="js/music.js"></script>
</html>
先建好基本的HTML框架。
css代码：
@charset "utf-8";
/* CSS Document */
.music {
height: 150px;
width: 150px;
background:rgba(98,91,91,0.9);
}
.pic_div {
position: relative;
}
.dot {
width: 15px;
height: 15px;

position: absolute;
border: 2px solid white;
border-radius: 50%;
top: 40px;

}
.disc {
width: 100px;
position: absolute;

transform: rotate(30deg);
}
#music_pic {
width: 100px;
position: absolute;
}
.music_program {
height: 2px;
width: 100px;
background: #555;
position: relative;
top: 100px;
}
.music_program div {
height: 100%;
width: 0%;
background: red;
}
.time {
width: 100px;
height: 20px;
position: relative;
top: 85px;
overflow: hide;
}
.time p {
padding-left: 33px;
}
.time p span:nth-of-type(2) {
padding: 0 5px;
}
.music_menu {
width: 150px;
height: 25px;
position: relative;
top: 85px;
}
.music_menu span {
width: 30px;
height: 25px;
display: inline-block;
cursor: pointer;
}
.music_menu span:nth-of-type(1) {
margin-left: 8px;
background: url(../images/music/pictures/back.png) no-repeat 7px;
}
.music_menu span:nth-of-type(2) {
margin-left: 14px;
background: url(../images/music/pictures/play.png) no-repeat 10px;
}
.music_menu span:nth-of-type(3) {
margin-left: 14px;
background: url(../images/music/pictures/forward.png) no-repeat 7px;
}
