爲什麼我的覆蓋層無法覆蓋自舉激活欄？

我正在嘗試在我的項目中添加overlay，以保護用戶在內容完全下載之前不會進行大量互動。這就是爲什麼我添加了覆蓋如下：爲什麼我的覆蓋層無法覆蓋自舉激活欄？

.overlay { 
    opacity: 0.5; 
    background: #000; 
    width: 100%; 
    height: 100%; 
    z-index: 10; 
    top: 0; 
    left: 0; 
    position: fixed; 
}

但問題是，覆蓋可以覆蓋所有整個頁面的100％，除此以外引導的導航欄。請幫助我如何覆蓋自舉導航欄上的覆蓋圖。

<div class="overlayIndex"></div> 
<div class="navbar navbar-default navbar-static-top navbar-fixed-top"> 
    <div class="container"> 
    <div class="row">.......</div> 
    </div> 
</div> 
<div ng-view="" autoscroll="true"></div>

設置你的'Z-index'到1031，看看有沒有做的伎倆？ – cwanjt

這樣設置'z-index'多於'navbar'：'z-index：9999' –

@cwanjt你可以發表答案嗎？ – ppshein

設置你的z-index到1031引導的navbar-fixed-top使用的1030的z-index設置上面這應該讓您的疊加覆蓋整個視口。

引導的CSS的navbar-fixed-top類：

.navbar-fixed-top { 
    position: fixed; 
    right: 0; 
    left: 0; 
    z-index: 1030; 
}
