## 添加Flex Superpowers到Tweet Embed
[在前一个挑战的基础上](https://github.com/freecodecamp/guides/tree/master/src/pages/responsive-web-design/css-flexbox/use-display-flex-to-position-two-boxes/index.md) 您需要将属性添加到正确的选择器中。这里的诀窍是识别正确的选择器然后你需要添加_displayflex;_属性。
标题将确保图片,名称,句柄和跟随按钮在水平方向上重新定位。
```CSS
header {
display: flex;
}
```
将名称和句柄对齐,看起来像一个句子。
```CSS
header .profile-name {
display:flex;
margin-left: 10px;
}
```
将属性添加到跟随按钮以及边距将使按钮居中到正确的大小。
```CSS
header .follow-btn {
display:flex;
margin: 0 0 0 auto;
}
```
在页脚元素上使用相同的想法。
