Step 1：先了解border的原理：



Step 2：HTML代码结构

Html代码


<section class="playContainer">

<li class="playBtn">

<a href="#" title="start">Start</a>

</li>

<li class="pauseBtn">

<a href="#" title="pause">Pause</a>

</li>

<li class="stopBtn">

<a href="#" title="stop">Stop</a>

</li>

<li class="forwardBtn playBtn">

<a href="#" title="forward">Forward</a>

<a href="#" title="forward">Forward</a>

</li>

<li class="rewindBtn">

<a href="#" title="rewind">Rewind</a>

<a href="#" title="rewind">Rewind</a>

</li>

<li class="ejectBtn">

<a href="#" class="arrow">Eject</a>

<a href="#" class="dash">Eject</a>

</li>

</section>

Step 3：画背景圆，position：relative

Css代码


.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


.playContainer { position: relative; float: left; background: rgba(0, 0, 0, 0.8); padding: 20px; }

.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; }

.playContainer a { border-style: solid; text-indent: -9999px; position: absolute; top: -8px; left: -3px; }

.playBtn a { border-color: transparent transparent transparent #fff; border-width: 8px 0 8px 12px; width: 0; height: 0; }

.pauseBtn a { border-color: transparent white; border-width: 0 6px; height: 15px; width: 6px; left: -9px; }

.stopBtn a { border: 7px solid #fff; height: 0; width: 0; left: -7px; top: -7px;}

.forwardBtn a { border-left-width: 8px; left: 1px; }

.forwardBtn a:first-child { margin-left: -7px; }

.rewindBtn a { border-width: 8px 8px 8px 0; border-color: transparent #fff transparent transparent; width: 0; height: 0; }

.rewindBtn a:first-child { margin-left: -7px; }

.ejectBtn a.arrow { border-width: 0 8px 8px 8px; border-color: transparent transparent #fff transparent; top:-26px; left:-8px; }

ectBtn a.dash { border-width: 0 0 4px; border-color: transparent transparent #fff; height: 0; width:16px; left: -8px; top: 4px; }
