# --description--

For now, hide your `#monsterStats` element with the `display` property. 不要更改任何其他样式。

# --hints--

应该有一个 `#monsterStats` 选择器。

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

`#monsterStats` 选择器应具有 `none` 的 `display` 属性。

```js
const display = new __helpers.CSSHelp(document).getStyle('#monsterStats')?.getPropertyValue('display');
assert.equal(display, 'none');
```

`#monsterStats` 选择器应该有一个 `1px solid black` 的 `border`。

```js
const border = new __helpers.CSSHelp(document).getStyle('#monsterStats')?.getPropertyValue('border');
assert.equal(border, '1px solid black');
```

`#monsterStats` 选择器应该有 `5px` 的填充（padding）。

```js
const padding = new __helpers.CSSHelp(document).getStyle('#monsterStats')?.getPropertyValue('padding');
assert.equal(padding, '5px');
```

`#monsterStats` 选择器应具有 `white` 的 `color`。

```js
const color = new __helpers.CSSHelp(document).getStyle('#monsterStats')?.getPropertyValue('color');
assert.equal(color, 'white');
```

`#monsterStats` 选择器应具有 `red` 的 `background-color`。

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