## Description
|
||
|
|
<section id="description">表单通常使用<code>checkboxes</code>来表示可能有多个答案的问题。复选框是一种类型的<code>input</code>您的每一个复选框可以嵌套自身的内<code>label</code>元素。通过将<code>input</code>元素包装在<code>label</code>元素内部，它将自动将复选框输入与其周围的标签元素相关联。所有相关的复选框输入应具有相同的<code>name</code>属性。通过在<code>label</code>元素上设置<code>for</code>属性以匹配关联<code>input</code>元素的<code>id</code>属性，最佳做法是明确定义复选框<code>input</code>与其对应<code>label</code>之间的关系。这是一个复选框的示例： <code><label for="loving"><input id="loving" type="checkbox" name="personality"> Loving</label></code> </section>
|
||
|
|
|
||
|
|
## Instructions
|
||
|
|
<section id="instructions">在表单中添加一组三个复选框。每个复选框应嵌套在自己的<code>label</code>元素中。这三者都应该分享<code>personality</code>的<code>name</code>属性。 </section>
|
||
|

|
||
|
|
- text: 确保每个<code>label</code>元素都有一个结束标记。
|
||
|
|
testString: 'assert(code.match(/<\/label>/g) && code.match(/<label/g) && code.match(/<\/label>/g).length === code.match(/<label/g).length, "Make sure each of your <code>label</code> elements has a closing tag.");'
|

|
||
