在悬停时弄一个弹出式标题卡?
问题说明
因此，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以链接文章和内容. PDF，幻灯片等也一样.
So for my website, I have a portfolio page and I want to design a simple image thumbnail for my Google doc or Word documents to link essays and stuff. The same for PDFs, Slides, etc.
我希望显示徽标或字母，当您将鼠标悬停在其上时，我希望标题卡弹出"并像弹起一样，然后当您悬停时，我希望该卡向下滑动并消失.
I want the logo or letter to be shown and when you hover on it, I want a title card to "pop" up and like bounce up a bit and then when you hover off, I want the card to slide down and disappear.
理论上，这就是我想要的样子:
In theory, this is what I want it to look like:
它只是向上滑动然后向下滑动还是向上射击，就像弹到正方形的底部然后掉下来一样反弹，没关系-我只是想知道如何做到这一点.
Whether it just slides up and then slides down or shoots up, bounces like it's hitting the bottom of the square, then falls down, doesn't matter - I'm just wondering how to do this.
正确答案
有很多不同的方法可以做到这一点.
There are a ton of different ways to do this.
这是CSS唯一的方式.
Here is a CSS only way.
基本上，您将为每个要具有悬停弹出标题的标题卡创建一个不同的类名.我为悬停弹出窗口中的内容使用了伪选择器.
Basically, you would create a different class name for each title card that you want to have a hover pop-up caption. I use a pseudo selector for the content in the hover pop up.
