# --description--

Add a `header` element within the `body` element and assign a class of `header` to it.

Inside the `header`, create an `h1` with `css flexbox photo gallery` as the text.

# --hints--

You should have a `header` element within your `body` element.

```js
assert.exists(document.querySelector('body')?.querySelector('header'));
```

Your `header` element should have a `class` with `header` as the value.

```js
assert(document?.querySelector('body')?.querySelector('header')?.classList?.contains('header'));
```

Your `header` element should have an `h1` element inside it.

```js
assert.exists(document.querySelector('.header')?.querySelector('h1'));
```

Your `h1` element should have the text `css flexbox photo gallery` inside it.

```js
assert(document?.querySelector('.header')?.querySelector('h1')?.innerText === 'css flexbox photo gallery');
```
