# --description--

Per sovrapporre meglio la montagna e l'elemento `.ground`, dai alla montagna un `margin-top` di `100px` e all'elemento `.ground` un `margin-top` di `-58px`.

# --hints--

Dovresti dare a `.left-mountain` un `margin-top` di `100px`.

```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.left-mountain')?.marginTop, '100px');
```

Dovresti dare a `.ground` un `margin-top` di `-58px`.

```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.ground')?.marginTop, '-58px');
```
