html - CSS 选项卡式 Div 不透明度

Question

我按照在线教程制作了这个整洁的小选项卡式 div 内容显示，但在设置背景不透明度时我似乎遇到了问题。通过这样做，它揭示了隐藏的内容。我试过在不同的图层上玩耍并设置不透明度，但我没有任何运气。这是一个 example你可以看到。让我知道你们的想法

Answer 1

在 CSS 部分 .content 中，将 background-color: rgba(0,0,0,.6); 替换为 background-color: #282828;

设置为 0.6 的背景透明度会显示位于显示层下的内容。

在 .content 部分中，将 color: #fff; 替换为 color: transparent;。

在 [type=radio]:checked ~ label ~ .content 部分添加 color: #fff;;在同一部分之后添加以下代码:

.content * {
visibility: hidden;
}

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

此代码使底层的文本颜色透明(=不可见!)并隐藏其中的所有元素。
