html - 背景不透明度影响子文本

Question

这可能是重复的帖子，但我似乎找不到我的 html/css 布局的解决方案，提前道歉：

HTML 代码：

<section class="palm-section text-center" id="palm-section">
    <div class="palm-img">
        <h1>Palm Hotel</h1>
        <div class="break-line"></div>
    </div>
</section>

代码：

 .palm-img h1{ /* Child text to background */
  position: absolute;
  top: 0;
  padding-top: 10px;
  font-size: 62px;
  color: white;
  font-weight: 400;
  z-index: 1;
}


.palm-img{ /* Background */
  position: relative;
  width: 100%;
  padding-top: 150px;
  padding-bottom: 100px;
  height: 100%;
  background: url(/images/the-palm-962785_1280.png) no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  color: white;
  background-size: cover;
  opacity: 0.5;
}

输出：

文本受到父背景不透明度的影响

更新：

CSS之前和之后不起作用，并且将背景埋在另一个div中似乎不起作用

.palm-img h1{ /* Child text to background */
  position: absolute;
  top: 0;
  padding-top: 10px;
  font-size: 62px;
  color: white;
  font-weight: 400;
  z-index: 1;
}


.palm-img{ /* Background */
  position: relative;
  width: 100%;
  padding-top: 150px;
  padding-bottom: 100px;
  height: 100%;
  color: white;
}

.palm-img::after {
  content: "";
  background: url(https://www.fillmurray.com/500/500) no-repeat center center fixed; 
  opacity: 0.5;
  top: 0;
  left: 0;
  bottom: 0;
  right: 0;
  position: absolute;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
}

<section class="palm-section text-center" id="palm-section">
    <div class="palm-img">
        <h1>Non transparent text</h1>
        <div class="break-line"></div>
    </div>
</section>

您可以使用 strached 伪元素作为背景
