Your first CSS selector—social.h2—is looking for the "social" element in the "h2", class, e.g.:
您的第一个 CSS 选择器social.h2——正在寻找“h2”类中的“social”元素，例如：
<social class="h2">
Class selectors are proceeded with a dot (.). Also, use a space () to indicate that one element is inside of another. To find an <h2>descendant of an element in the socialclass, try something like:
类选择器以点 ( .)开头。此外，使用空格 ( ) 表示一个元素在另一个元素内部。要<h2>在social类中查找元素的后代，请尝试以下操作：
.social h2 {
color: pink;
font-size: 14px;
}
To get a better understanding of CSS selectors and how they are used to reference your HTML, I suggest going through the interactive HTML and CSS tutorials from CodeAcademy. I hope that this helps point you in the right direction.
为了更好地理解 CSS 选择器以及它们如何用于引用您的 HTML，我建议您阅读 CodeAcademy的交互式 HTML 和 CSS 教程。我希望这有助于为您指明正确的方向。

To do links, you can do
要做链接，你可以做
.social h2 a:link {
color: pink;
font-size: 14px;
}
You can change the hover, visited, and active link styling too. Just replace "link" with what you want to style. You can learn more at the w3schools page CSS Links.
您也可以更改悬停、访问和活动链接样式。只需将“链接”替换为您想要的样式即可。您可以在 w3schools 页面CSS 链接 中了解更多信息。
