# --description--

Begin with your standard HTML boilerplate. Add a `DOCTYPE` declaration, an `html` element, a `head` element, and a `body` element.

Add a `meta` tag with the appropriate `charset` and a `meta` tag for mobile responsiveness within the `head` element.

# --hints--

Your code should contain the `DOCTYPE` reference.

```js
assert(code.match(/<!DOCTYPE/gi));
```

You should include a space after the `DOCTYPE` reference.

```js
assert(code.match(/<!DOCTYPE\s+/gi));
```

You should define the document type to be `html`.

```js
assert(code.match(/<!DOCTYPE\s+html/gi));
```

You should close the `DOCTYPE` declaration with a `>` after the type.

```js
assert(code.match(/<!DOCTYPE\s+html\s*>/gi));
```

Your `html` element should have an opening tag.

```js
assert(code.match(/<html\s*>/gi));
```

Your `html` element should have a closing tag.

```js
assert(code.match(/<\/html\s*>/));
```

Your `html` element should be below the `DOCTYPE` declaration.

```js
assert(code.match(/(?<!<html\s*>)<!DOCTYPE\s+html\s*>/gi));
```

You should have an opening `head` tag.

```js
assert(code.match(/<head\s*>/i));
```

You should have a closing `head` tag.

```js
assert(code.match(/<\/head\s*>/i));
```

You should have an opening `body` tag.

```js
assert(code.match(/<body\s*>/i));
```

You should have a closing `body` tag.

```js
assert(code.match(/<\/body\s*>/i));
```

The `head` and `body` elements should be siblings.

```js
assert(document.querySelector('head')?.nextElementSibling?.localName === 'body');
```

The `head` element should be within the `html` element.

```js
assert([...document.querySelector('html')?.children].some(x => x?.localName === 'head'));
```

The `body` element should be within the `html` element.

```js
assert([...document.querySelector('html')?.children].some(x => x?.localName === 'body'));
```

You should have two `meta` elements.

```js
const meta = document.querySelectorAll('meta');
assert(meta?.length === 2);
```

One `meta` element should have a `name` set to `viewport`, and `content` set to `width=device-width, initial-scale=1.0`.

```js
const meta = [...document.querySelectorAll('meta')];
const target = meta?.find(m => m?.getAttribute('name') === 'viewport' && m?.getAttribute('content') === 'width=device-width, initial-scale=1.0' && !m?.getAttribute('charset'));
assert.exists(target);
```

The other `meta` element should have the `charset` attribute set to `UTF-8`.

```js
const meta = [...document.querySelectorAll('meta')];
const target = meta?.find(m => !m?.getAttribute('name') && !m?.getAttribute('content') && m?.getAttribute('charset')?.toLowerCase() === 'utf-8');
assert.exists(target);
```
