CSS Tabbed Divs opacity

Question

我跟着教程在線，使這個整齊的小標籤的div內容顯示，但我似乎有一個問題，在背景設置不透明度。通過這樣做，它揭示了隱藏的內容。我嘗試過在不同層次上玩弄並設置不透明度，但我沒有運氣。這是你可以看到的example。讓我知道你們想

新的答案

在第.content與color: transparent;取代color: #fff;。

在部分[type=radio]:checked ~ label ~ .content中添加color: #fff;;相同的部分之後添加以下代碼：

.content * { 
visibility: hidden; 
} 

[type=radio]:checked ~ label ~ .content * { 
visibility: visible; 
} 

該代碼使得下層透明的文本顏色和隱藏在它裏面的所有元素（=無形！）。

Answer 2

可以使用從background-color: rgba(0,0,0,.5);
