# --description--

以右邊的嵌入推文爲例， 一些元素換一個佈局方式或許更好看。 上一個挑戰演示了 `display: flex`， 現在你需要把它添加到推文內嵌的多個組件中，調整它們的位置。

# --instructions--

請爲下列項目添加 CSS 屬性 `display: flex`。 注意，以下 CSS 選擇器已爲你寫好：

`header`、header 中的 `.profile-name`、header 中的 `.follow-btn`、header 中的 `h3` 和 `h4`、`footer` 以及 footer 中的 `.stats`。

# --hints--

`.follow-btn` 應在頁面上呈現。 請關閉廣告攔截器等任何擴展。

```js
assert($('.follow-btn').length > 0 && $('.follow-btn').css('display') !== 'none');
```

`header` 的 `display` 屬性值應爲 `flex`。

```js
assert($('header').css('display') == 'flex');
```

`footer` 的 `display` 屬性值應爲 `flex`。

```js
assert($('footer').css('display') == 'flex');
```

`h3` 的 `display` 屬性值應爲 `flex`。

```js
assert($('h3').css('display') == 'flex');
```

`h4` 的 `display` 屬性值應爲 `flex`。

```js
assert($('h4').css('display') == 'flex');
```

`.profile-name` 的 `display` 屬性值應爲 `flex`。

```js
assert($('.profile-name').css('display') == 'flex');
```

`.follow-btn` 的 `display` 屬性值應爲 `flex`。

```js
assert($('.follow-btn').css('display') == 'flex');
```

`.stats` 的 `display` 屬性值應爲 `flex`。

```js
assert($('.stats').css('display') == 'flex');
```
