您可以使用svgsfilter来获得类似的效果。

body {
  background: tan;
}
svg {
  position: relative;
  width: 500px;
  left: 50%;
  transform: translateX(-50%);
}
p {
  color: peru;
  padding: 45px;
}

<svg width="500" height="500">
  <defs>
    <filter id="filter" height="1.4" width="1.4">
      <feTurbulence baseFrequency="0.12" numOctaves="2" type="fractalNoise" result="result1" />
      <feDisplacementMap in2="result1" scale="99" result="result2" xChannelSelector="R" in="SourceGraphic" />
      <feComposite in2="result2" in="SourceGraphic" operator="atop" result="fbSourceGraphic" />
    </filter>
  </defs>
  <rect fill="saddlebrown" filter="url(#filter)" width="500" height="500" x="0" y="0" />
  <foreignObject width="500" height="500">
    <div>
      <p>

我相信自 2014 年最初发布以来，事情已经取得了进展。现在是 2017 年，我使用 CSS 来创建粗糙/撕裂边缘的外观。请参阅此处的代码示例。我相信通过更多的工作，我可以让它更令人信服……但我喜欢这给我的目的的结果。

clip-path: polygon(3% 0, 7% 1%, 11% 0%, 16% 2%, 20% 0, 23% 2%, 28% 2%, 32% 1%, 35% 1%, 39% 3%, 41% 1%, 45% 0%, 47% 2%, 50% 2%, 53% 0, 58% 2%, 60% 2%, 63% 1%, 65% 0%, 67% 2%, 69% 2%, 73% 1%, 76% 1%, 79% 0, 82% 1%, 85% 0, 87% 1%, 89% 0, 92% 1%, 96% 0, 98% 3%, 99% 3%, 99% 6%, 100% 11%, 98% 15%, 100% 21%, 99% 28%, 100% 32%, 99% 35%, 99% 40%, 100% 43%, 99% 48%, 100% 53%, 100% 57%, 99% 60%, 100% 64%, 100% 68%, 99% 72%, 100% 75%, 100% 79%, 99% 83%, 100% 86%, 100% 90%, 99% 94%, 99% 98%, 95% 99%, 92% 99%, 89% 100%, 86% 99%, 83% 100%, 77% 99%, 72% 100%, 66% 98%, 62% 100%, 59% 99%, 54% 99%, 49% 100%, 46% 98%, 43% 100%, 40% 98%, 38% 100%, 35% 99%, 31% 100%, 28% 99%, 25% 99%, 22% 100%, 19% 99%, 16% 100%, 13% 99%, 10% 99%, 7% 100%, 4% 99%, 2% 97%, 1% 97%, 0% 94%, 1% 89%, 0% 84%, 1% 81%, 0 76%, 0 71%, 1% 66%, 0% 64%, 0% 61%, 0% 59%, 1% 54%, 0% 49%, 1% 45%, 0% 40%, 1% 37%, 0% 34%, 1% 29%, 0% 23%, 2% 20%, 1% 17%, 1% 13%, 0 10%, 1% 6%, 1% 3%);
