SVG 阴影 1


SVG <feDropShadow>

<feDropShadow> 滤镜用于在输入图形上创建阴影效果

Sorry, your browser does not support inline SVG.

以下是 SVG 代码

示例

<svg height="110" width="110" xmlns="http://www.w3.org/2000/svg">
  <defs>
    <filter id="f1">
      <feDropShadow dx="12" dy="14" stdDeviation="1" flood-opacity="0.7"/>
    </filter>
  </defs>
  <rect width="90" height="90" fill="yellow" filter="url(#f1)" />
</svg>
亲自试一试 »

代码解释

  • <filter> 元素的 id 属性为滤镜定义了一个唯一的名称
  • 阴影效果由 <feDropShadow> 元素定义
  • dx 属性定义阴影的 x 偏移量
  • dy 属性定义阴影的 y 偏移量
  • stdDeviation 属性定义阴影的模糊量
  • flood-opacity 属性定义阴影的不透明度(从 0 到 1)
  • <rect> 元素的 filter 属性将元素指向 "f1" 滤镜
