纯CSS3实现超炫酷的3D开关切换按钮 – 码农网

这是一款用纯CSS3实现的开关切换按钮，按钮一共有四组样式，每一组按钮都有3D的视觉效果。和普通按钮不同的是，它们都有着开关切换的用途，也就是说点击按钮可以在两个不同的状态下进行切换，效果非常棒。实现原理也是比较简单的，主要利用CSS3重写checkbox的样式，3D的效果也是CSS3实现的。

这里我们对第二种样式进行简单的代码说明。

HTML代码

CSS代码：

.switch.demo2 {  width: 50px;  height: 100px;}.switch.demo2 label {  background: #cbc7bc;  margin: 0 auto;  border-radius: 5px;  box-shadow:      inset 0 1px 0 white,      0 0 0 1px #999,      0 0 5px 1px rgba(0,0,0,0.2),      0 2px 0 rgba(255,255,255,0.6),      inset 0 10px 1px #e5e5e5,      inset 0 11px 0 rgba(255,255,255,0.5),      inset 0 -45px 3px #ddd;}.switch.demo2 label:after {  content: '';  position: absolute;  top: -20px;  left: -25px;  bottom: -20px;  right: -25px;  background: #ccc;  background: -moz-linear-gradient(#ddd, #bbb);  background: -ms-linear-gradient(#ddd, #bbb);  background: -o-linear-gradient(#ddd, #bbb);  background: -webkit-gradient(linear, 0 0, 0 100%, from(#ddd), to(#bbb));  background: -webkit-linear-gradient(#ddd, #bbb);  background: linear-gradient(#ddd, #bbb);  z-index: -1;  border-radius: 5px;  border: 1px solid #bbb;  box-shadow:      0 0 5px 1px rgba(0,0,0,0.15),      0 3px 3px rgba(0,0,0,0.3),      inset 0 1px 0 rgba(255,255,255,0.5);}.switch.demo2 label:before {  content: '';  position: absolute;  width: 8px;  height: 8px;  background: #666;  top: -13px;  left: 20px;  border-radius: 50%;  box-shadow:      0 120px 0 #666,      0 1px 0 white,      0 121px 0 white;}.switch.demo2 input:checked ~ label {  background: #d2cbc3;  box-shadow:      inset 0 1px 0 white,      0 0 0 1px #999,      0 0 5px 1px rgba(0,0,0,0.2),      inset 0 -10px 0 #aaa,      0 2px 0 rgba(255,255,255,0.1),      inset 0 45px 3px #e0e0E0,      0 8px 6px rgba(0,0,0,0.18);}
