如何在悬停时制作 Pop-Up 标题卡？

Question

所以对于我的网站，我有一个投资组合页面，我想为我的 Google 文档或 Word 文档设计一个简单的图像缩略图到 link 文章和东西。 PDF、幻灯片等也是如此

我想要显示徽标或字母，当你将鼠标悬停在上面时，我想要一张标题卡片 "pop" 向上弹起一点，然后当你悬停时，我想要这张卡片向下滑动并消失。

理论上，这就是我想要的样子：

不管它是先向上滑动然后向下滑动，还是向上弹起，像碰到正方形底部一样弹起，然后掉下来，都没有关系 - 我只是想知道如何做到这一点。

Answer 1

有很多不同的方法可以做到这一点。

这是 CSS 唯一的方法。

基本上，您可以为每张想要悬停 pop-up 标题的标题卡创建不同的 class 名称。我为悬停弹出窗口中的内容使用了伪选择器。

希望对您有所帮助！
