通过 bootstrap 创建好看的单选框复选框

第一步：自定义单选框、复选框的层叠样式表，并将其映入

build.css:

.checkbox {
  padding-left: 20px; }
.checkbox label {
  display: inline-block;
  vertical-align: middle;

第二步：引入相关头文件

<link rel="stylesheet" type="text/css" href="https://cdn.bootcss.com/font-awesome/4.6.0/css/font-awesome.min.css"/>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/bootstrap@3.3.7/dist/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">

第三步：使用案例：

<!-- checkbox -->
<div class="checkbox">
    <input type="checkbox" name="item[1]" id="item1" value=""/>
    <label for="item1">选项一</label>
</div>
<div class="checkbox checkbox-success">
    <input type="checkbox" name="item[2]" id="item2" value="" checked="checked" />
    <label for="item2">选项二</label>
</div>
<div class="checkbox checkbox-info">
    <input type="checkbox" name="item[3]" id="item3" value="" checked="checked"/>
    <label for="item3">选项三</label>
</div>

<!-- radio -->
<div class="radio">
    <input type="radio" name="radio" id="radio1" value="" />
    <label for="radio1">ITEM 1</label>
</div>
<div class="radio radio-success">
    <input type="radio" name="radio" id="radio2" value="" checked="checked" />
    <label for="radio2">ITEM 2</label>
</div>

第四步：代码整合，（注：build.css与该HTML在同一目录下）

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>创建一个好看的 CheckBox</title>

        <link rel="stylesheet" type="text/css" href="build.css"/>
        <link rel="stylesheet" type="text/css" href="https://cdn.bootcss.com/font-awesome/4.6.0/css/font-awesome.min.css"/>
    </head>
    <body>
        <!-- checkbox -->
        <div class="checkbox">
            <input type="checkbox" name="item[1]" id="item1" value=""/>
            <label for="item1">选项一</label>
        </div>
        <div class="checkbox checkbox-success">
            <input type="checkbox" name="item[1]" id="item2" value="" checked="checked" />
            <label for="item2">选项二</label>
        </div>
        <div class="checkbox checkbox-info">
            <input type="checkbox" name="item[1]" id="item3" value="" checked="checked"/>
            <label for="item3">选项三</label>
        </div>
        
        <!-- radio -->
        <div class="radio">
            <input type="radio" name="radio" id="radio1" value="" />

        <div class="radio radio-success">

            <label for="radio2">ITEM 2</label>
        </div>
        
    </body>
</html>
