Step 1：先了解border的原理：

Step 2：HTML代码结构

Html代码

4. Start
8. Pause
12. Stop
16. Forward
17. Forward
21. Rewind
22. Rewind
26. Eject
27. Eject

Step 3：画背景圆，position：relative

Css代码

1. .playContainer li { position: relative; float: left; border: 25px solid #404040; color: #404040; height: 0; width:0; -webkit-border-radius: 100%; -moz-border-radius: 100%; -o-border-radius: 100%; border-radius: 100%; margin: 0 20px; }

Step 4：画stop按钮，要让按钮居中。

按钮相对外层圆圈绝对定位，从圆圈的中心开始，所以要调整top和left值

stop按钮边长14px，相对原点需要向上、向左移动7个像素，居中。

全部的CSS如下：

Css代码

1. .playContainer { position: relative; float: left; background: rgba(0, 0, 0, 0.8); padding: 20px; }
2. .playContainer li { position: relative; float: left; border: 25px solid #404040; color: #404040; height: 0; width:0; -webkit-border-radius: 100%; -moz-border-radius: 100%; -o-border-radius: 100%; border-radius: 100%; margin: 0 20px; }
3. .playContainer a { border-style: solid; text-indent: -9999px; position: absolute; top: -8px; left: -3px; }
5. .playBtn a { border-color: transparent transparent transparent #fff; border-width: 8px 0 8px 12px; width: 0; height: 0; }

12. .rewindBtn a:first-child { margin-left: -7px; }
14. .ejectBtn a.arrow { border-width: 0 8px 8px 8px; border-color: transparent transparent #fff transparent; top:-26px; left:-8px; }
