工具提示文字在悬停时不显示

标签： html css hover tooltip

这是一个简单的图库，我想在天数悬停时显示工具提示文字。在这种情况下，我想在1月1日悬停时显示新年文本。我从w3schools获取了工具提示代码。我有逻辑错误或句法吗？

d['system1']['attr1'] = value_of_attr1

工具提示的包含元素需要定位，以便工具提示出现＆＃34;相对＆＃34;当悬停在它上面时，从包含元素（.newyear）。

这可以通过将position属性声明为绝对定位的嵌套元素（.newyear）的包含元素（.tooltiptext）来完成，例如：< / p> 

.newyear {
  position: relative;
}

摘要：

当定位为绝对（例如：position: absolute）并相对于文档定位时，工具提示将从正常文档流中取出。

要将 relative 放置到父（包含）元素，该父元素必须相对于定位 - 工具提示现在相对于父元素定位

只需更改此类的这些属性：

.newyear .tooltiptext {
  visibility: hidden;
  width: 120px;
  background-color: #555;
  color: #fff;
  text-align: center;
  border-radius: 6px;
  padding: 5px 0;
  position: absolute;
  /*z-index: 1;*/
  /*bottom: 125%;*/
  left: 50%;
  /* margin-left: -60px; */ 
  top:20%; /* New line */
  opacity: 0;
  transition: opacity 1s;
}

我确实评论了"/* */"疑难解答行。我没有删除他们中的任何一个，你可以看到你做错了什么。在这里，您可以看到新工作的数字“1”以上的工作工具提示：
