# --description--
Rotate the `.back-mountain` element by `45deg` clockwise. Then, give it a `left` property of `110px`, and a `top` property of `225px`.
# --hints--
You should use the `transform` property to rotate the element.
```js
assert.notEmpty(new __helpers.CSSHelp(document).getStyle('.back-mountain')?.transform);
```
You should give `.back-mountain` a `transform` of `--fcc-expected--`, but found `--fcc-actual--`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.back-mountain')?.transform, 'rotate(45deg)');
```
You should give `.back-mountain` a `left` property.
```js
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('.back-mountain')?.left);
```
You should give `.back-mountain` a `left` property of `--fcc-expected--`, but found `--fcc-actual--`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.back-mountain')?.left, '110px');
```
You should give `.back-mountain` a `top` property.
```js
assert.isNotEmpty(new __helpers.CSSHelp(document).getStyle('.back-mountain')?.top);
```
You should give `.back-mountain` a `top` property of `--fcc-expected--`, but found `--fcc-actual--`.
```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.back-mountain')?.top, '225px');
```
