昨天我找到了一个只用css制作滑动菜单的代码。 当我在我的 css 文件中为所有 ul、li、a 元素设置样式时，一切都很好。 当我尝试在具体的 div 中设置列表样式时出现问题，然后当我将鼠标悬停在顶部元素上时，子元素出现但是当我尝试指向它们时它们隐藏了 working it_hides_when_hover . 谁能解释为什么在 div 中它不起作用？
#nav ul {
list-style-type:none;
margin:0;
padding:0;
position: absolute;
}
/*Create a horizontal list with spacing*/
#nav li {
display:inline-block;
float: left;
margin-right: 1px;
}
/*Style for menu links*/
#nav li a {
display:block;
min-width:140px;
height: 50px;
text-align: center;
line-height: 50px;
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
color: #fff;
background: #2f3036;
text-decoration: none;
}
/*Hover state for top level links*/
#nav li:hover a {
background: #19c589;
}
/*Style for dropdown links*/
#nav li:hover ul a {
background: #f3f3f3;
color: #2f3036;
height: 40px;
line-height: 40px;
}
/*Hover state for dropdown links*/
#nav li:hover ul a:hover {
background: #19c589;
color: #fff;
}
/*Hide dropdown links until they are needed*/
#nav li ul {
display: none;
}
/*Make dropdown links vertical*/
#nav li ul li {
display: block;
float: none;
}
/*Prevent text wrapping*/
#nav li ul li a {
width: auto;
min-width: 100px;
padding: 0 20px;
}
/*Display the dropdown on hover*/
#nav ul li a:hover + .hidden, .hidden:hover {
display: block;

这是一个修改过的例子:

#nav ul {
list-style-type: none;
margin: 0;
padding: 0;
position: absolute;
}
/*Create a horizontal list with spacing*/
#nav li {
display: inline-block;
float: left;
margin-right: 1px;
}
/*Style for menu links*/
#nav li a {
display: block;
min-width: 140px;
height: 50px;
text-align: center;
line-height: 50px;
font-family: "Helvetica Neue", Helvetica, Arial, sans-serif;
color: #fff;
background: #2f3036;
text-decoration: none;
}
/*Hover state for top level links*/
#nav li:hover a {
background: #19c589;
}
/*Style for dropdown links*/
#nav li:hover ul a {
background: #f3f3f3;
color: #2f3036;
height: 40px;
line-height: 40px;
}
/*Hover state for dropdown links*/
#nav li:hover ul a:hover {

}
/*Hide dropdown links until they are needed*/
#nav li ul {

}
/*Make dropdown links vertical*/
#nav li ul li {

}
/*Prevent text wrapping*/
#nav li ul li a {

min-width: 100px;

}
/*Display the dropdown on hover*/
#nav ul li:hover .hidden {
display: block;
