# --description--

Create a CSS rule that targets the class `two` and set its `background-color` property to `green`. 

Also, create a separate CSS rule that targets the class `three` and set its `background-color` to `blue`.

# --hints--

You should use a class selector to target the class `two`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.two'));
```

Your `.two` CSS rule should have a `background-color` property set to `green`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.two')?.backgroundColor === 'green');
```

You should use a class selector to target the class `three`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.three'));
```

Your `.three` CSS rule should have a `background-color` property set to `blue`.

```js
assert(new __helpers.CSSHelp(document).getStyle('.three')?.backgroundColor === 'blue');
```
