【问题描述】：

我已经为我的网站创建了一个主页，其中包含所有方面的概述。现在，只有带有超链接的图像，但是当您将鼠标悬停在图像上时，我想添加有关特定 div 中每个链接的额外信息。如果这样更容易，我可以使用 JavaScript。我只为#xchat 添加了一些文本，而不是为其余部分添加了尝试。这是 CSS：

<style>
  .explanation {
    height: 50px;
    width: 200px;
    border: 2px solid black;
    display: flex;
    align-items: center;
    justify-content: center;
  }
  #xclicker, #xchat, #xtictactoe, #xboxpusher, #xhome, #xtba {
    display:none;
  }
  .clicker:hover ~ .explanation #xclicker {
    display:block;
  }
  .chat:hover ~ .explanation #xchat {
    display:block;
  }
  .tictactoe:hover ~ .explanation #xtictactoe {
    display:block;
  }
  .boxpusher:hover ~ .explanation #xboxpusher {
    display:block;
  }
  .home:hover ~ .explanation #xhome {
    display:block;
  }
  .tba:hover ~ .explanation #xtba {
    display:block;
  }
</style>

这里是 HTML

   <div class="table">

非常感谢任何帮助。提前致谢。

欢迎来到 SO。帮自己一个忙 - 在 .js 文件中使用集中式 JavaScript。你的 HTML 现在真的很难用所有（重复的）内联 JS 阅读。
或 CSS，如果可能的话，用于悬停效果。

【解决方案1】：

你可以这样做：

<!-- Some images -->
<img style="height: 50px;" 
     src="https://cdn.glitch.com/17adc8fb-ebe3-48f0-9734-f3611ee24069%2F121-1215914_question-mark-icons-question-mark-in-circle-png.png?v=1603200311478" 
     onmouseover="explanation.innerHTML = 'Help';" 
     onmouseout="explanation.innerHTML = '';">

<img style="height: 50px;"
     src="https://cdn.glitch.com/17adc8fb-ebe3-48f0-9734-f3611ee24069%2F25694.svg?v=1603184266071'"
     onmouseover="explanation.innerHTML = 'Home';"
     onmouseout="explanation.innerHTML = '';">
    
<!-- The explanation div -->
<div id="explanation" ></div>

当然，您可以为所有元素添加样式。
