您可以使用svg的filter s來獲得類似的效果。

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>

    </foreignObject> 
 
</svg>

我會使用SVG。您可以在Illustrator/Sketch中輕鬆獲得精確的形狀，並從那裏導出SVG文件。

這隻適用於圖像，並且完全適用於圖像。如果它是您擔心的圖片的額外往返 - 將其嵌入到CSS中很容易，因此它很簡潔快速。您可以使用任何您喜歡的圖像類型作爲實際圖像 - 對於此特定目的，PNG或SVG是最可能的候選對象（PNG實際上更容易平鋪）。

我相信事情的進展，因爲這最初發布在2014年這一年是2017年，現在，我已經使用CSS創建粗糙/撕邊的外觀。在這裏看到代碼示例。我相信有更多的工作可以讓它更具說服力......但我喜歡這個結果給我的目的。
