# --description--
在之前的挑战中,我们把嵌入推文的 `header` 和 `footer` 的 `flex-direction` 属性值设为 row(行)。相似地,把 `.profile-name` 选择器中的元素竖着排列会好看一点。
# --instructions--
请给 header 的 `.profile-name` 元素添加 CSS 属性 `flex-direction`,并将其值设为 column。
# --hints--
`.profile-name` 所选择的元素应有 `flex-direction` 属性,且其属性值应为 column。
```js
assert($('.profile-name').css('flex-direction') == 'column');
```
