# --description--

现在我们需要快速设置一些样式。 首先将 `body` 的 `background-color` 设置为 `darkblue`。

# --hints--

应该有一个 `body` 选择器。

```js
const body = new __helpers.CSSHelp(document).getStyle('body');
assert.exists(body);
```

`body` 选择器应该将 `background-color` 属性设置为 `darkblue`。

```js
const background = new __helpers.CSSHelp(document).getStyle('body')?.getPropertyValue('background-color');
assert.equal(background, 'darkblue');
```
