使用 CSS 将子元素的背景色与父元素的背景图像混合

Question

我想将元素的背景颜色与父元素的背景图像混合在一起。将css属性"background-blend-mode"设置为"multiply"，仅当在同一元素上设置颜色和图像时，它才有效。但是我想存档在同一背景图像上混合的不同颜色 - 所以我必须将背景图像与孩子们的颜色混合在一起。有没有办法到达那里？

.bg {
  background-image: url(data:image/png;base64,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);

Answer 1

它

mix-blend-mode不是background-blend-mode ¹

.bg {
  background-image: url(data:image/png;base64,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);
}
.mixit-green {
  background-color: #ddffdd;
  mix-blend-mode: multiply;
  padding: 50px;
}
.mixit-blue {
  background-color: #ddddff;
  mix-blend-mode: multiply;
  padding: 50px;
}

<div class="bg">
  <div class="mixit-green"></div>
  <div class="mixit-blue"></div>
</div>

background-blend-mode在具有多个背景时使用。所以你可以像下面这样写上面：

.bg {
  padding:100px;
  background-image:
    linear-gradient(#ddffdd 50%,#ddddff 0),
  url(data:image/png;base64,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);
  background-blend-mode: multiply;
}

<div class="bg">

¹定义每个背景图层的混合模式。

每个背景层

必须与其下方的元素背景层和元素的背景颜色混合。背景图层不得与元素后面的内容混合，相反，它们必须像呈现到隔离组中一样。^裁判
