【问题描述】：

我需要一些帮助在 CSS 中重新创建它（如果可能的话）：

这是我目前所拥有的：

.bg {
  background-image: url('https://images.unsplash.com/photo-1501706362039-c06b2d715385?auto=format&fit=crop&w=1070&q=60&ixid=dW5zcGxhc2guY29tOzs7Ozs%3D');
  background-repeat: no-repeat;
  background-position: center center;
  padding: 100px 50px;
}

.text {
  background: #ed1c24;
  mix-blend-mode: multiply;
}

.text p {
  font-family: "Helvetica";
  font-weight: bold;
  font-size: 32px;
  color: #fff;
  margin: 0;
  padding: 40px;
}

<div class="bg">
  <div class="text">
    <p>
      These artistic movements were a refelection of the million of people who lived and worked here. To them, "I ❤ NY" could be read as a rallying cry.
    </p>
  </div>
</div>

有一个带有背景图像的 div，覆盖该 div 的是另一个带有红色 bg 颜色和 mix-blend-mode: multiply 的 div。看起来颜色混合工作正常，但是有没有一种方法可以使白色文本不受影响并且像示例图像中那样不透明的纯白色？

【解决方案1】：

您可以像这样使用伪元素并在其上应用mix-blend-mode: multiply：

.bg {
  background-image: url('https://images.unsplash.com/photo-1501706362039-c06b2d715385?auto=format&fit=crop&w=1070&q=60&ixid=dW5zcGxhc2guY29tOzs7Ozs%3D');
  background-repeat: no-repeat;
  background-position: center center;
  padding: 100px 50px;
}

.text {
  position: relative;
}

.text:before {
  content: "";
  position: absolute;
  top: 0;
  right: 0;
  left: 0;
  bottom: 0;
  background: #ed1c24;
  mix-blend-mode: multiply;
  z-index: 0;
}

.text p {
  font-family: "Helvetica";
  font-weight: bold;
  font-size: 32px;
  color: #fff;
  margin: 0;
  padding: 40px;
  z-index: 2;
  position: relative;
}

<div class="bg">
  <div class="text">
    <p>
      These artistic movements were a refelection of the million of people who lived and worked here. To them, "I ❤ NY" could be read as a rallying cry.
    </p>
  </div>
</div>
