我想知道你们是否可以帮助我，我已经开始为我的博客创建一个下拉菜单，在我看来它进展顺利，直到我意识到一旦我将鼠标悬停在下拉菜单上它就会消失光标，链接没问题，但是当我将光标悬停在下拉菜单上时，它会消失。

源代码:

        }

最佳答案

所以我对你的代码做了一个简化版本(以后你应该先做这个)并且能够缩小问题的范围。 #main 部分的位置与下拉列表混淆，它出现在它们的顶部。所以我做的简单事情就是将 z-index 添加到下拉列表中

#navMenu ul li ul {
  position:absolute;
  visibility:hidden;
  top:30px;
  z-index: 1;
}
#navMenu ul li:hover ul {
  // display: block;
  visibility:visible;
  // display: block; 
}

a:link {
    color:yellow;
    text-decoration:none;
    padding: 10px;
}
a:visited {
    color:yellow;
}
a:hover {
    background-color:none;
    color:green;
    text-decoration:bold;
    text-decoration:underline;
    font-weight:bold;
}
#Title {
    font: 30px Candara;
    -webkit-box-shadow:rgba(110, 110, 110, .4) 10px 10px 10px;
    padding-top: 5px;
    padding-left: 100px;
    color: orange;
}
