用纯css改变默认的radio和checkbox的样式

利用css的label的伪类（::before）代替checkbox和radio效果：

优点：需要图片来调整选中前和选中后的样式，纯css搞定
缺点：兼容性，IE8以下不支持

在线例子:

<head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="ie=edge"> <title>css改变默认的radio和checkbox的样式</title> <style> input[type="radio"], input[type='checkbox'] { display: none; }

input[type='radio']+label::before,
input[type='checkbox']+label::before {
  content: '';
  display: inline-block;
   15px;
  height: 15px;
  margin-right: 6px;
  vertical-align: middle;
  border: 1px solid #E4E4E4;
  border-radius: 50%;
  background: #FFFFFF;
  background-image: url('https://i.loli.net/2018/07/20/5b517d0bf066a.png');
  background-position: 0px 0px;
}

input[type='radio']:hover+label::before,
input[type='checkbox']:hover+label::before {
  background-position: -15px 0px;
}

input[type='radio']:checked+label::before,
input[type='checkbox']:checked+label::before {
  background-position: -15px -15px;
}

</style> </head> <body> <p>单选框</p> <input type="radio" name="sex" value="man" id="man" checked> <label for="man">男</label> <input type="radio" name="sex" value="female" id="female"> <label for="female">女</label> <p>多选框</p> <input type="checkbox" name="fruits" value="apple" id="apple" checked> <label for="apple">苹果</label> <input type="checkbox" name="fruits" value="orange" id="orange"> <label for="orange">橙子</label> </body>

代码:

<!DOCTYPE html>
<html>

<head>
  <meta charset="UTF-8">
  <meta http-equiv="X-UA-Compatible" content="ie=edge">
  <title>css改变默认的radio和checkbox的样式</title>
  <style>
    input[type="radio"],
    input[type='checkbox'] {
      display: none;
    }

    input[type='radio']+label::before,
    input[type='checkbox']+label::before {
      content: '';
      display: inline-block;
       15px;
      height: 15px;
      margin-right: 6px;
      border-radius: 100%;
      vertical-align: middle;
      border: 1px solid #E4E4E4;
      background: #FFFFFF;
      background-image: url('https://i.loli.net/2018/07/20/5b517d0bf066a.png');
      background-position: 0px 0px;
    }

    input[type='radio']:hover+label::before,
    input[type='checkbox']:hover+label::before {
      background-position: -15px 0px;
    }

    input[type='radio']:checked+label::before,
    input[type='checkbox']:checked+label::before {
      background-position: -15px -15px;
    }
  </style>
</head>

<body>
  <p>单选框</p>
  <input type="radio" name="sex" value="man" id="man" checked>
  <label for="man">男</label>
  <input type="radio" name="sex" value="female" id="female">
  <label for="female">女</label>
  <p>多选框</p>
  <input type="checkbox" name="fruits" value="apple" id="apple" checked>
  <label for="apple">苹果</label>
