# --description--

现在到了最后一个 `fieldset`。 如果你想允许用户上传个人资料图片，应该怎么做呢？

类型为 `file` 的 `input` 可以实现。 添加一个 `label`，其文本为 `Upload a profile picture:`，嵌套一个 `input` 以接收上传的文件。

# --hints--

应该添加一个 `label` 并设置其文字为 `Upload a profile picture:`。

```js
assert.match(document.querySelector('fieldset:nth-child(3) > label')?.innerText, /Upload a profile picture:/i);
```

应该在 `label` 元素内添加一个 `input` 元素。

```js
assert.exists(document.querySelector('fieldset:nth-child(3) > label > input'));
```

`input` 元素的 `type` 应该为 `file`。

```js
assert.equal(document.querySelector('fieldset:nth-child(3) > label > input')?.type, 'file');
```
