HTML 中使用 mix-blend-mode

HTML

<div class="isolate">
  <div class="circle circle-1"></div>
  <div class="circle circle-2"></div>
  <div class="circle circle-3"></div>
</div>

CSS

.circle {
  width: 80px;
  height: 80px;
  border-radius: 50%;
  mix-blend-mode: screen;
  position: absolute;
}

.circle-1 {
  background: red;
}

.circle-2 {
  background: lightgreen;
  left: 40px;
}

.circle-3 {
  background: blue;
  left: 20px;
  top: 40px;
}

.isolate {
  isolation: isolate; /* Without isolation, the background color will be taken into account */
  position: relative;
}

结果

SVG 中使用 mix-blend-mode

SVG

<svg>
  <g class="isolate">
    <circle cx="40" cy="40" r="40" fill="red"/>
    <circle cx="80" cy="40" r="40" fill="lightgreen"/>
    <circle cx="60" cy="80" r="40" fill="blue"/>
  </g>
</svg>

CSS

circle { mix-blend-mode: screen; }
.isolate { isolation: isolate; } /* Without isolation, the background color will be taken into account */

结果
