#menu a {
    text-decoration:none;

#menu li:hover {

    padding-top:20px;
/*  background-color:#7D169D;*/
    background-image: url(../images/pinkcloud.png); 
    background-repeat:no-repeat;  
/*  background-size: 100%;
    background-size: 60px 90px; */
    top:40px;
    height:60px;
    width:90px;
    position:absolute; 
}
.nav-flag-plane {  
        float:left; 
        margin-top:32px;
        margin-left:0px;
        width: 109px; 
        height: 71px;
} 

.nav-menu-cloude {  
        float:left; 
        margin-top:32px;
        margin-left:35px;
        width: 109px; 
        height: 75px;
} 

使用上面给出的css和悬停效果的图像。问题是鼠标悬停在第一个菜单项上的其他项目变得缩小而第二个项目变为隐藏。
