Step 1:先了解border的原理:
Step 2:HTML代码结构
Html代码
- Start
- Pause
- Stop
- Forward
- Forward
- Rewind
- Rewind
- Eject
- Eject
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; }

- .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; }
