# --description--

Add a `link` element inside your `head` element. Set its `rel` attribute to `stylesheet` and its `href` attribute to `styles.css`.

# --hints--

Your code should have a `link` element.

```js
assert.isNotNull(document.querySelector('link'));
```

You should not change your existing `head` tags. Make sure you did not delete the closing tag.

```js
const headElements = document.querySelectorAll('head');
assert.strictEqual(headElements?.length, 1);
```

You should have one `link` element.

```js
assert.strictEqual(document.querySelectorAll('link')?.length, 1);
```

Your `link` element should be inside your `head` element.

```js
const headContentRegex = /(?<=<head\s*>)[\S|\s]*(?=<\/head\s*>)/;
const headElementContent = code.match(headContentRegex);

const headElement = document.createElement("head");
headElement.innerHTML = headElementContent;
assert.isNotNull(headElement.querySelector('link'));
```

Your `link` element should have a `rel` attribute with the value `stylesheet`.

```js
const linkElement = document.querySelector('link');
const rel = linkElement?.getAttribute("rel");
assert.strictEqual(rel, "stylesheet");
```

Your `link` element should have an `href` attribute with the value `styles.css`.

```js
const linkElement = document.querySelector('link');
assert.strictEqual(linkElement?.dataset.href, "styles.css");
```
