将非透明文本添加到半透明 div 容器中？
Adding non transparent text into semi transparent div container?
我正在尝试使用 <p> 标签在 4 个使用半透明标签的黑框内添加文本。我希望容器内的文本完全不透明。
根据我的阅读，我知道这是 CSS 的一个恼人的挫折。我看到了使用 rgba() 颜色作为背景或使用 .png 图像的选项。我在父容器上尝试了 rgba() 方法，但没有用。
我真的不想使用图像，因为图像文件大小会增加加载时间。我尝试过的一切都没有奏效。有人可以就如何处理这个问题给我一些建议吗？下面是我的代码。
.wrapper {
position: relative;
padding: 0 15px;
}
.responsive-image {
width: 100%;
height: auto;
}
#statement {
position: absolute;
text-align: center;
top: 280px;
left: 300px;
font-size: 50px;
font-weight: bold;
color: #ffffff;
}
.opaque-box {
position: absolute;
top: 670px;
left: 15px;
background: #000000;
opacity: 0.4;
text-align: center;
width: 25%;
height: 30%;
border-top: solid 2px #ffffff;
border-bottom: solid 2px #ffffff;
}
p.box-content {
padding-top: 50px;

font-size: 20px;
font-style: italic;

这是我发现对我有用的方法。我不得不使用 top 和 left 属性将文本定向到下面是合适的解决方案的代码。我确信有一种更简洁的方法可以做到这一点，但我目前还不知道。
