Question

我按照在线教程制作了这个整齐的小标签div内容显示，但在背景上设置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。我试过在不同层面玩耍并设置不透明度，但我没有运气。这是你可以看到的example。让我知道你们的想法

Answer 1

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

Answer 2

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

背景透明度设置为0.6会显示位于显示图层下的内容。

新答案

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

在[type=radio]:checked ~ label ~ .content部分中添加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。
