css - SVG模式和渐变一起

有没有办法使用过滤器或SVG中的任何方法将图案和渐变同时应用于元素？

我不想创建重复的元素（任何形状）来实现此目的。它的维护开销。

下图是我预期输出的示例。

<svg xmlns='http://www.w3.org/2000/svg' width='100%' height='100%'>
<defs>
    <pattern id='tile' patternUnits='userSpaceOnUse' width='75' height='75' viewBox='0 0 50 50'>
        <line x1='1' y1='0' x2='51' y2='50' stroke='#19203d' stroke-width='2'/>
        <line x1='49' y1='0' x2='-1' y2='50' stroke='#19203d' stroke-width='2'/>
        <line x1='50' y1='0' x2='0' y2='50' stroke='#313763' stroke-width='2'/>
        <line x1='0' y1='0' x2='50' y2='50' stroke='#313763' stroke-width='2'/>
    </pattern>
    <radialGradient id='l' cx='50%' cy='200%' fy='0' r='201%'>
        <stop offset='0%' style='stop-color:#fff; stop-opacity:.1;' />
        <stop offset='10%' style='stop-color:#000; stop-opacity:0.1;' />
        <stop offset='30%' style='stop-color:#000; stop-opacity:0.3;' />
        <stop offset='90%' style='stop-color:#000; stop-opacity:0.55;' />
        <stop offset='100%' style='stop-color:#000; stop-opacity:.6' />
    </radialGradient>
</defs>
<rect fill='#39466b' width='100%' height='100%'/>
<rect fill='url(#tile)' width='100%' height='100%'/>
<rect width='100%' height='100%' fill='url(#l)'/></svg>

  我不想重复填充梯度和图案的元素。上面的代码已复制了元素。

最佳答案

尽管这仍然会重复元素，但它在defs标签中这样做，意味着您可以将其应用于一个可见元素。

body,
html {
  height: 100%;
  width: 100%;
  margin: 0;
  padding: 0;
}

<svg xmlns='http://www.w3.org/2000/svg' width='100%' height='100%'>
<defs>
<pattern id='tile' patternUnits='userSpaceOnUse' width='75' height='75' viewBox='0 0 50 50'>
    <line x1='1' y1='0' x2='51' y2='50' stroke='#19203d' stroke-width='2'/>
    <line x1='49' y1='0' x2='-1' y2='50' stroke='#19203d' stroke-width='2'/>
    <line x1='50' y1='0' x2='0' y2='50' stroke='#313763' stroke-width='2'/>
    <line x1='0' y1='0' x2='50' y2='50' stroke='#313763' stroke-width='2'/>
</pattern>
<radialGradient id='l' cx='50%' cy='200%' fy='0' r='201%'>
    <stop offset='0%' style='stop-color:#fff; stop-opacity:.1;' />
    <stop offset='10%' style='stop-color:#000; stop-opacity:0.1;' />
    <stop offset='30%' style='stop-color:#000; stop-opacity:0.3;' />
    <stop offset='90%' style='stop-color:#000; stop-opacity:0.55;' />
    <stop offset='100%' style='stop-color:#000; stop-opacity:.6' />
</radialGradient>
<rect id="bgRect" fill='#39466b' width='100%' height='100%'/>
<rect id="gradientRect" fill='url(#l)' width='100%' height='100%'/>
<rect id='tileRect' fill="url(#tile)" width='100%' height='100%'/>

<filter id="test" color-interpolation-filters="sRGB" y="0">
<feImage xlink:href="#bgRect" result="bg" />
<feImage xlink:href="#tileRect" result="tile" />
<feImage xlink:href="#gradientRect" result="waves" />
<feMerge>
      <feMergeNode in="bg" />
    <feMergeNode in="tile" />
    <feMergeNode in="waves" />
  </feMerge>
  </filter>

  </defs>

<rect filter='url(#test)' width='100%' height='100%'/>
</svg>

它使用rects作为feImage的源，但不幸的是，FireFox不支持此功能，而IE支持不完整。

这绝不是一个完美的解决方案，但可以说明前进的方向。
