放下 - 子菜单菜单消失时悬停

Question

一切都很好，除了子菜单，而悬停...它消失在悬停。我确定悬停中存在一些问题。即

.dropdown-content a:hover + .dropdown-submenu { 
    display: block; 
} 

.icon-cadet-left { 
 
    float: right;

Answer 1

你只是忘了添加.dropdown-submenu:hover您display: block;规则。如果没有，则子菜单会消失，因为您不再悬停在a标签上。

.icon-cadet-left { 
 
    float: right; 
 
} 
 
.dropbtn { 
 
    overflow: hidden; 
 
    width: 300px; 
 
    background-color: #338d99; 
 
    color: white; 
 
    padding: 16px; 
 
    font-family: 'Play'; 
 
    font-size: 20px; 
 
    border: none; 
 
    cursor: pointer; 
 
    text-transform: uppercase; 
 
    letter-spacing: 2px;

    background-color: #e0e0e0;

Answer 2

您应该使用

.dropdown-content:hover .dropdown-submenu { 

而不是

.dropdown-content a:hover + .dropdown-submenu { 

其原因是，一旦你移动鼠标悬停.dropdown-submenua节点不再徘徊，因此.dropdown-submenu不是blocked。

这里是一个工作版本：

.icon-cadet-left { 
 
    float: right; 
 
} 
 
.dropbtn { 
 
    overflow: hidden; 
 
    width: 300px; 
 
    background-color: #338d99; 
 
    color: white; 
 
    padding: 16px; 
 
    font-family: 'Play'; 
 
    font-size: 20px; 
 
    border: none; 
 
    cursor: pointer; 
 
    text-transform: uppercase; 
 
    letter-spacing: 2px; 
 
} 
 
.dropdown { 
 
    position: relative; 
 
    display: block; 
 

 
} 
 
.dropdown-content { 
 
    display: none; 
 
    position: absolute; 
 
    background-color: #e0e0e0; 
 
    box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2); 
 
    margin:0px; 
 
} 
 
.dropdown-content a { 
 
    width: 300px; 
 
    color: black; 
 
    font-family: 'Play'; 
 
    letter-spacing: 2px; 
 
    padding: 12px 16px; 
 
    text-decoration: none !important; 
 
    display: block; 
 
    text-align: center; 
 
    border-bottom: 0.1em solid #333; 
 
    border-radius: 5%; 
 
    text-transform: uppercase; 
 
    
 
} 
 
.dropdown-submenu { 
 
    display: none; 
 
    margin:0px; 
 
    background-color: #e0e0e0; 
 
    position: absolute; 
 
    box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2); 
 
    left: 100%; 
 
    top: 0px; 
 
} 
 

 
.dropdown-submenu a { 
 
    width: 300px; 
 
    color: black; 
 
    font-family: 'Play'; 
 
    letter-spacing: 2px; 
 
    padding: 12px 16px; 
 
    text-decoration: none !important; 
 
    display: block; 
 
    text-align: center; 
 
    border-bottom: 0.1em solid #333; 
 
    border-radius: 5%; 
 
    text-transform: uppercase; 
 

 
} 
 

 
.dropdown-content a:hover { 
 
    background-color: #f1f1f1; 
 
    color:#909090; 
 
} 
 
.dropdown-submenu a:hover { 
 
    background-color: #f1f1f1 
 
} 
 
.dropdown:hover .dropdown-content {
