当容器必须有溢出：隐藏时,是否有一种方法,最好没有js,在容器上方定位和显示工具提示,而不会影响工具提示并被容器夹住？
这是一个例子来说明这个问题：
.container {
overflow: hidden;
position: relative;
margin: auto;
width: 50%;
border: 3px solid green;
padding: 10px;
height: 70px;
background: lightblue;
text-align: center;
}
a.tooltips {
position: relative;
display: inline;
}
a.tooltips span {
position: absolute;
width: 140px;
color: #FFFFFF;
background: #000000;
height: 96px;
line-height: 96px;
text-align: center;
visibility: hidden;
border-radius: 8px;
Box-shadow: 4px 3px 10px #800000;
}
a.tooltips span:after {
content: '';
position: absolute;
bottom: 100%;
left: 50%;
margin-left: -8px;
width: 0;
height: 0;
border-bottom: 8px solid #000000;
border-right: 8px solid transparent;
border-left: 8px solid transparent;
}
a:hover.tooltips span {
visibility: visible;
opacity: 0.7;
top: 30px;
left: 50%;
margin-left: -76px;
z-index: 999;
}
<div class="container">
<a class="tooltips" href="#">Hover me for Tooltip
<span>Tooltip</span></a>
<div>

解决方法
有一种方法可以在这些条件下显示元素,方法是将其置于绝对位置(作为一个简单的包装器)并包含相对定位的工具提示.
所以你需要添加一个元素.
一个重要条件：具有溢出的父级：隐藏不得自行定位,否则工具提示不会在此父级上方弹出/显示.
