# --description--

キャンパー (freeCodeCamp ユーザー) に対し、バイオグラフィーに何を入力したらいいかのアイデアを与えるために、`placeholder` 属性を使います。 `placeholder` はテキストの値を受け取り、ユーザーが入力を始めるまでの間そのテキストが表示されます。

`textarea` の `placeholder` を `I like coding on the beach...` に設定してください。

# --hints--

`textarea` に `placeholder` 属性を追加する必要があります。

```js
assert.isNotEmpty(document.querySelector('fieldset:nth-child(3) > label:nth-child(4) > textarea')?.placeholder);
```

`placeholder` の値を `I like coding on the beach...` に設定する必要があります。

```js
assert.match(document.querySelector('fieldset:nth-child(3) > label:nth-child(4) > textarea')?.placeholder, /^I like coding on the beach\.{3,4}$/);
```
