很简单。在包装器 div 中创建一些文本，然后命令文本在悬停包装器时显示。下面是此逻辑的演示。

HTML:

<div class="image">
   <p>I'm some very interesting text!</p>
  <div class="arrow"><span>></span></div>
</div>

CSS:

 p{
   color: #fff;
   opacity: 0;
   font-weight: bold;
   text-align: center;
   font-size:32px;
   color: red;
  /* bring your own prefixes */
  transform: translate(0, 50%);
   transition: all .5 ease;
}


.image:hover p {
  visibility: visible;
  opacity: 1;
}
