# --description--
|
||
|
|
|
||
|
|
在之前兩個挑戰中，我們使用了 `flex-direction` 屬性，值爲 `row`。 這個屬性還能創建一個列，讓子元素豎直排列在 flex 容器中。
|
||
|
|
|
||
|
|
# --instructions--
|
||
|
|
|
||
|
|
請給 `#box-container` 元素添加 CSS 屬性 `flex-direction`，並將其屬性值設置爲 `column`。
|
||
|
|
|
||
|
|
# --hints--
|
||
|
|
|
||
|
|
`#box-container` 應有 `flex-direction` 屬性，其屬性值應爲 `column`。
|
||
|
|
|
||
|
|
```js
|
||
|
|
assert($('#box-container').css('flex-direction') == 'column');
|
||
|
|
```
