# --description--

Add a new `div` element inside of your `.canvas` element.

Give the new `div` the `class` attribute with a value of `one`. This will be your first rectangle.

# --hints--

You should create a new `div` element.

```js
assert(document.querySelectorAll('div').length === 3);
```

You should nest the new `div` element within your `.canvas` element.

```js
assert(document.querySelector('.canvas').children[0].tagName === 'DIV');
```

Your new `div` should have a `class` attribute with a value `one`.

```js
assert(document.querySelector('.canvas').children[0].className.split(' ').includes('one'));
```
