# --description--

下一个表单主题与单选按钮的可访问性有关。在上一个挑战中，每个单选按钮都有一个包含 `for` 属性的 `label` 标签，`for` 的属性值指向相关选项的 `id`。然而单选按钮通常成组出现，而且用户必须选择其中一项。本次挑战介绍一种可以语义化呈现单选按钮组的方法。

我们可以使用 `fieldset` 标签将单选按钮组包含在里面，通常还会使用 `legend` 标签来为单选按钮组提供文字说明。屏幕阅读器也可以朗读这些文字。

当选项的含义很明确时，如“性别选择”，`fieldset` 与 `legend` 标签可以省略。这时，使用包含 `for` 属性的 `label` 标签就足够了。

举个例子：

```html
<form>
  <fieldset>
    <legend>Choose one of these three items:</legend>
    <input id="one" type="radio" name="items" value="one">
    <label for="one">Choice One</label><br>
    <input id="two" type="radio" name="items" value="two">
    <label for="two">Choice Two</label><br>
    <input id="three" type="radio" name="items" value="three">
    <label for="three">Choice Three</label>
  </fieldset>
</form>
```

# --instructions--

当用户使用邮件注册时，Camper Cat 想知道他们的忍者等级。通过上一个挑战的学习，Camper Cat 创建了一组单选按钮，并为每个选项的 `label` 标签添加了 `for` 属性，但是 Camper Cat 的代码依然需要你的帮助。请将包含单选按钮组的 `div` 标签替换为 `fieldset` 标签；将 `p` 标签替换为 `legend` 标签。

# --hints--

应存在 1 个 `fieldset` 标签包含单选按钮组。

```js
assert($('fieldset').length == 1);
```

确保 `fieldset` 标签是闭合的。

```js
assert(
  code.match(/<\/fieldset>/g) &&
    code.match(/<\/fieldset>/g).length === code.match(/<fieldset>/g).length
);
```

应存在 1 个包含询问用户忍者等级内容文字的 `legend` 标签。

```js
assert($('legend').length == 1);
```

不应存在 `div` 标签。

```js
assert($('div').length == 0);
```

不应存在包含询问用户忍者等级内容文字的 `p` 标签。

```js
assert($('p').length == 4);
```
