就是这个开关，代码是从weui上拷贝出来的。 至于weui自己百度吧 ^_^~
开关代码如下：
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Document</title> <style type="text/css"> .weui_switch { -webkit-appearance: none; -moz-appearance: none; appearance: none; position: relative; width: 52px; height: 32px; border: 1px solid #DFDFDF; outline: 0; border-radius: 16px; box-sizing: border-box; background: #DFDFDF; -webkit-rtl-ordering: logical; -webkit-user-select: text; cursor: auto; display: inline-block; text-align: start; } .weui_switch:before { content: " "; position: absolute; top: 0; left: 0; width: 50px; height: 30px; border-radius: 15px; background-color: #FDFDFD; -webkit-transition: -webkit-transform .3s; transition: transform .3s; } .weui_switch:after { content: " "; position: absolute; top: 0; left: 0; width: 30px; height: 30px; border-radius: 15px; background-color: #FFFFFF; box-shadow: 0 1px 3px rgba(0, 0, 0, 0.4); -webkit-transition: -webkit-transform .3s; transition: transform .3s; } .weui_switch:checked { border-color: #04BE02; background-color: #04BE02; } .weui_switch:checked:before { -webkit-transform: scale(0); transform: scale(0); } .weui_switch:checked:after { -webkit-transform: translateX(20px); transform: translateX(20px); } </style> </head> <body> <input type='checkbox' class='weui_switch'> </body> </html>
