为什么我的工具提示没有出现在 link 悬停时？

Question

几天来我一直在尝试让我的工具提示显示出来，但没有任何进展。当不透明度为 1 时，它们可以使用此块 select 或 .sidebar ul li .tooltip {} 出现在边栏中，如果您想查看它们的外观。

我尝试将 z-index 添加到 .sidebar ul li a:hover .tooltip {} select 或者与 opacity:1 一起，但这不起作用。

我还尝试更改 'hover' 以应用于 'li' 而不是 'a' 标签，但这并没有改变任何东西。并尝试将其添加到两者 (.sidebar ul li:hover a:hover .tooltip {}) 但也不起作用。

这是不透明度的问题，还是 selector 的问题？我觉得我什么都试过了。

当我 select 浏览器开发工具中的工具提示元素并强制进入悬停状态时，您可以看到工具提示在正确的位置，但就在所有内容的后面或不可见。

如有任何帮助，我们将不胜感激。

.sidebar ul li a:hover .tooltip {

  top: 50%;

Answer 1

CSS 中几乎没有问题，您需要更新代码中的以下更改。

变化一：

从第 32

行的 ul CSS 中删除 overflow: hidden;

ul {
  list-style-type: none;
  margin: 0;
  padding: 0;
  position: -webkit-sticky; /* Safari */
  position: sticky;
  top: 0;
}

变化2：

在第 123

行 sidebar ul li a .tooltip CSS 添加 display: none;

.sidebar ul li a .tooltip {
  position: absolute;
  color: #343434;
  display: none;
  left: 130px;
  top: 0;
  transform: translate(-50%, -50%);
  border-radius: 6px;
  height: 35px;
  width: 122px;
  background: #fff;
  line-height: 35px;
  text-align: center;
  box-shadow: 0 5px 10px rgba(0, 0, 0, 0.2);
  transition: 0s;
  pointer-events: none;
}

变化3：

在第 141

行 sidebar.active ul li .tooltip CSS 添加 !important

.sidebar.active ul li .tooltip {
  display: none !important;
}

下面的代码片段也更新了所有更改，希望对您有所帮助。谢谢
