我該如何解決這個導航菜單不透明問題？

它的實際工作中的jsfiddle就好了，但是當我在瀏覽器中運行它有一個與在默認全子菜單中選擇問題大小位置（頂部對齊）保持在0不透明度。在Chrome和Safari中都是一樣的，幾乎可以肯定的是這是一個不透明的問題，在動畫命令後不能自行解決，但這只是奇怪的，它只發生在默認的子菜單上。如果你刪除不透明度：0;來自＃fadein-menu-1/2/3/4 ID的行，子菜單再次工作。

我覺得我只是想念一個公然，愚蠢的小東西......但我無法爲我的生活找到它。真的很感謝這裏的一些幫助。

對不起這個，但我從菜單中重建起來 - 你不會真正能夠看到問題，直到我找到衝突的確切來源。這個菜單處於很多其他代碼的中間，我仍然無法理解不透明問題。我想我會再次打擾你們，如果我找到它，並不能找出它.. – Joel

問題：

animation: fadein 1s ease-in 1.4s 1 forwards;

您試圖淡出其中有opacity:0;的元素。您的動畫一旦運行就意味着元素淡入，然後元素將返回默認樣式（opacity:0;）。所以你看不到那些元素。

解決方案：從默認樣式中移除不透明度。

#fadein-menu-1 { 
    /* Remove from all the elements */ 
    //opacity:0; 
    -webkit-animation: fadein 1s ease-in 1s 1 forwards; /* Safari, Chrome and Opera > 12.1 */ 
     -moz-animation: fadein 1s ease-in 1s 1 forwards; /* Firefox < 16 */ 
     -ms-animation: fadein 1s ease-in 1s 1 forwards; /* Internet Explorer */ 
     -o-animation: fadein 1s ease-in 1s 1 forwards; /* Opera < 12.1 */ 
      animation: fadein 1s ease-in 1s 1 forwards; 
}

@Joel這對您有幫助嗎？ – Alex

感謝您抽出寶貴時間看看它 - 從理論上講，我理解您解釋的問題是什麼，Jsfiddle證明它是正確的，但我發現的解決方案是不同的。我仍然在所有的順序菜單淡入淡出的不透明度：0我通過我的CSS並開始無效的零碎，我覺得可能會導致衝突，我發現身體標記導致這個問題。我已經忘記了它已經是什麼了。一些愚蠢的事情，當然......但是這是我覺得我必須接受它沒有得到答案就行得通的那種情況之一。 – Joel

@Joel歡迎您。 – Alex

我該如何解決這個導航菜單不透明問題？
