# --description--

To give the effect of a mountain range, add another mountain, by creating a new `div` immediately after `.left-mountain`, and give the new `div` the `class` of `back-mountain`.

# --hints--

You should add a new `div` within `body`.

```js
assert.equal(document.querySelectorAll('body > div')?.length, 4);
```

You should give the `div` a `class` of `back-mountain`.

```js
assert.include(document.querySelector('div:not(.left-mountain, .ground, .penguin)')?.className, 'back-mountain');
```

You should place `.back-mountain` after `.left-mountain`.

```js
assert.strictEqual(document.querySelector('.left-mountain')?.nextElementSibling, document.querySelector('.back-mountain'));
```
