2.CSS编写

代码如下（示例）：

这里通过type=checkbox的input是否checked编写打开与关闭样式动画效果

after和before伪元素来设置开、关文字

/* Button 1 */
#button-1 .knobs:before {content: 'YES';position: absolute;top: 4px;left: 4px;width: 20px;height: 10px;color: #fff;font-size: 10px;font-weight: bold;text-align: center;line-height: 1;padding: 9px 4px;background-color: #03a9f4;border-radius: 50%;transition: 0.3s cubic-bezier(0.18, 0.89, 0.35, 1.15) all;
}#button-1 .checkbox:checked + .knobs:before {content: 'NO';left: 42px;background-color: #f44336;
}#button-1 .checkbox:checked ~ .layer {background-color: #fcebeb;
}#button-1 .knobs,
#button-1 .knobs:before,
#button-1 .layer {transition: 0.3s ease all;
}
