自己常用的改变checkbox样式的两个方法：
一.利用background用图片代替checkbox效果
缺点：你首先得有一张好看的图片
优点：浏览器兼容性好
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>chec</title> <style>
#wrapper {margin: 20px auto;}
#wrapper .input_check {position: absolute;width: 20px;height: 20px;visibility: hidden;}
#wrapper span {position: relative;}
#wrapper .input_check+label {display: inline-block;width: 20px;height: 20px;background: url(checkbox2.png) no-repeat;background-position: -31px -3px;}
#wrapper .input_check:checked+label {background-position: -5px -3px;} </style>
</head>
<body>
<h3>利用background用图片代替checkbox效果</h3>
<div id="wrapper">
<span><input type="checkbox"class="input_check" id="check1"><label for="check1"></label></span>
<span><input type="checkbox"class="input_check" id="check2"><label for="check2"></label></span>
</div>
</body>
</html>
二.利用css的：after跟transform属性代替checkbox效果
优点：不需要图片，纯css搞定
缺点：兼容性，不用说你也知道我指的是哪个奇葩浏览器
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>chec</title> <style> #container {margin: 20px auto;}
#container span {position: relative;}
#container .input_check {position: absolute;visibility: hidden;}
#container .input_check+label {display: inline-block;width: 16px;height: 16px;border: 1px solid #fd8845;}
#container .input_check:checked+label:after {content: "";position: absolute;left: 2px;bottom: 12px;width: 9px;height: 4px;
border: 2px solid #fd8845;border-top-color: transparent;border-right-color: transparent;
-ms-transform: rotate(-60deg);
-moz-transform: rotate(-60deg);
-webkit-transform: rotate(-60deg);
transform: rotate(-45deg);}
</style>
</head>
<body> <h3>利用css的：after跟transform属性代替checkbox效果</h3>
<div id="container">
<span><input type="checkbox"class="input_check" id="check3"><label for="check3"></label></span>
<span><input type="checkbox"class="input_check" id="check4"><label for="check4"></label></span>
</div>
</body>
