Html 如何定位隐藏的语音气泡

我正在建立我的第一个网站，当你们像这样悬停在图片上时，我有一些隐藏的语音泡泡出现

但是，我不知道如何影响语音气泡的定位测量，如何使语音气泡在它下面的框的中心对齐

任何帮助都将不胜感激

HTML:

---

假设隐藏消息将以链接为中心

HTML

<div id="container">
    <a href="#" class="hoverbubble">Hover over me!
        <span>Hidden message here.</span>
    </a>
</div>

---

将容器

div

设置为

position:relative

从

a

标记中删除

position:relative

将

position:relative

从a标记更改为div容器将允许绝对定位的

span

相对于容器而不是

a

标记对齐

将

span

设置为

position:absolute

通过编辑值

top:40%，对齐
span
；左：11%

现在可以相对于容器定位
span
元素

如果气泡位于框的中心，那么（）我会如何影响固定高度的语音气泡，文本会溢出？你能给我发一份关于这个问题的JSFIDLE，我来看看吗？可能
overflow:hidden
会有帮助吗？去掉
white space:nowrap从
a.hoverbubble:hover span
这将排序宽度。要使框跨越文本的高度，只需取出
height:100px
from
a.hoverbubble:hover span
