HTML CSS導航兒童造型錯誤

Question

我很難在Wordpress主題導航中定位我的下拉菜單。當我將鼠標懸停在屏幕上方時，它們不會顯示在靠近導航欄的位置，並且靠近屏幕的左上角。

我的CSS如下：

#main-navigation { 

    clear: both; 
    float: left; 
    font-size: 17px; 
    margin-top: 30px; 
    width: 938px; 
} 
#main-navigation > ul { width: 105%; margin-left:auto; margin-right:auto; } 
#main-navigation > ul > li {} 
#main-navigation > ul > li:hover { transparent; } 
#main-navigation > ul > li:first-child { border: medium none; } 
#main-navigation > ul > li > a { 
    margin-right:20px; 
    border-bottom: 2px solid #6a6a65; 
    color: #181818; 
    display: block; 
    font-weight: bold; 
    height: 48px; 
    line-height: 48px; 
    padding: 0 29px; 
// text-shadow: 0 1px 0 #AD581D;\ 
    text-transform:uppercase; 

} 
#main-navigation > ul > li:first-child > a { 
    background: url("./assets/img/home.png") no-repeat scroll center 10px transparent; 
// border: medium none; 
color:#6a6a65; 
border-bottom: 2px solid #6a6a65; 
    overflow: hidden; 
    padding: 0 25px; 
    text-indent: -999px; 
    width: 31px; 
} 

#main-navigation > ul > li:first-child > a:hover { 
border-bottom: 2px solid #fa7d4c; 

} 
#main-navigation a:hover { text-decoration: none; border-bottom: 2px solid #fa7d4c;} 
#main-navigation ul li:hover ul { display: block; } 
#main-navigation ul ul { 
    border-bottom: 1px solid #333333; 
    display: none; 
    left: 0; 
    padding-top: 20px; 
    position: absolute; 
    top: 148px; 
    white-space: nowrap; 
    z-index: 1000; 
    background: url("./assets/img/dd-arrow.png") 33px 10px no-repeat; 
} 
#main-navigation ul ul li { 
    background: none repeat scroll 0 0 #3C3C3D; 
    border-left: 1px solid #333333; 
    border-right: 1px solid #333333; 
    border-top: 1px solid #2C2C2C; 
    box-shadow: 3px 4px 0 rgba(0, 0, 0, 0.3), 0 1px 0 #444445 inset; 
    float: none; 
    font-size: 16px; 
} 
#main-navigation ul ul li:first-child { 
    border-top: medium none; 
    box-shadow: 3px 4px 0 rgba(0, 0, 0, 0.3); 
} 
#main-navigation ul ul a { 
    color: #FFF; 
    display: block; 
    height: 48px; 
    line-height: 48px; 
    padding: 0 29px; 
    text-shadow: 0 1px 0 #2D2D2E; 
} 
#main-navigation ul ul a:hover { color: #ccc; } 

任何幫助將不勝感激，因爲我已經花了很長時間尋找錯誤的開始阻撓我。

感謝一幫傢伙！

你需要通過默認告訴從主導航孩子的絕對位置，而不是屏幕，Iguess因爲HTML代碼丟失:)

#main-navigation { 
    position:relative; /* tells absolute child to take coordonates from here */ 
    clear: both; 
    float: left; 
    font-size: 17px; 
    margin-top: 30px; 
    width: 938px; 
}
