Answer 1

试试这个：

ul li:hover > a {
  border: 1px solid red;
}

＆＃34;＆GT;＆＃34;意味着我们只与直接孩子建立关系，而不是嵌套孩子。

Answer 2

将悬停链接更改为以下内容。

ul li li:hover a {
  border: 1px solid red;
}

Answer 3

如果您想仅在悬停的边缘设置边框，请替换代码

ul li:hover a {
  border: 1px solid red;
}

<强>与

ul li a:hover {
  border: 1px solid red;
}

CSS仅限下拉边框＆＃39; ul li ul li：将鼠标悬停在＆＃39;
