【问题描述】：

我也试过了，但是不行

<style>
/* Tooltip container */
.tooltip 
  position: relative;
  display: inline-block;
  border-bottom: 1px dotted black; /* If you want dots under the hoverable text */


/* Tooltip text */
.tooltip .tooltiptext 
  visibility: hidden;
  width: 120px;
  background-color: black;
  color: #fff;
  text-align: center;
  padding: 5px 0;
  border-radius: 6px;
 
  /* Position the tooltip text - see examples below! */
  position: absolute;
  z-index: 1;


/* Show the tooltip text when you mouse over the tooltip container */
.tooltip:hover .tooltiptext 
  visibility: visible;

</style>

<div class="tooltip">Hover over me
  <span class="tooltiptext">Tooltip text</span>
</div>

【参考方案1】：

你必须使用 aria- describeby 属性

<a href="#" aria-describedby="myinfo">Texto de el Link</a>
<div role="tooltip" id="myinfo">Contenido de el tooltip]</div>
