# --description--
By now, you should be familiar with the basic elements an HTML page should have.
Set up your code with a `DOCTYPE` declaration, an `html` element, a `head` element, and a `body` element.
# --hints--
Your code should have a `<!DOCTYPE html>` declaration.
```js
assert(code.match(/<!DOCTYPE html>/i));
```
Your code should have an `html` element.
```js
assert(document.querySelectorAll('html').length === 1);
```
Your code should have a `head` element within the `html` element.
```js
assert(document.querySelectorAll('head').length === 1);
```
Your code should have a `body` element within the `html` element.
```js
assert(document.querySelectorAll('body').length === 1);
```
Your `head` element should come before your `body` element.
```js
assert(document.querySelector('body').previousElementSibling.tagName === 'HEAD');
```
