svg lineargradient hidden如果svg隐藏在单独的类中

svg css html

基本上,如果svg隐藏在parallel元素中,则会隐藏lineargradient填充。

.mobile {
  display: none;
}

.content-svg {
  border: 1px solid black;
}

<div class="desktop">
  <!-- stuff here -->
</div>

<div class="mobile">
  <svg class="mobile-svg" height="150" width="400">
  <defs>
    <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
    </linearGradient>
  </defs>
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad1)" />

  </svg>
</div>

<div class="content">
  <svg class="content-svg" height="150" width="400">
  <defs>
    <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
    </linearGradient>
  </defs>
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad1)" />

正如您在上面的代码片段中看到的,svg元素在那里,lineargradient填充被隐藏

如果我在css中将填充改为纯色集,它会按预期工作,这似乎只在渐变填充时发生。

现在这只是我整个问题的一个基本示例,我想避免重新创建svg,因为我在vue中使用它并创建了一个可重用的svg组件

请考虑不同的渐变ID:

.mobile {
  display: none;
}

.content-svg {
  border: 1px solid black;
}

<div class="desktop">
  <!-- stuff here -->
</div>

<div class="mobile">
  <svg class="mobile-svg" height="150" width="400">
  <defs>
    <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
    </linearGradient>
  </defs>
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad1)" />

  </svg>
</div>

<div class="content">
  <svg class="content-svg" height="150" width="400">
  <defs>
    <linearGradient id="grad2" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
    </linearGradient>
  </defs>
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad2)" />

或者,只有在两个SVG中使用的渐变色相同时才考虑使用渐变色(相关: Gradients hidden using SVG symbols )

.mobile{
显示:无;
}

.content svg{
边框:1px纯黑;
}

<div class="desktop">
  <!-- stuff here -->
</div>

  <svg  height="0" width="0">
  <defs>
    <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
    </linearGradient>
  </defs>
  </svg>
<div class="mobile">
  <svg class="mobile-svg" height="150" width="400">
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad1)" />

<div class="content">
  <svg class="content-svg" height="150" width="400">
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad1)" />

  </svg>
</div>

重复相同的id是无效的,只有第一个id将被同时考虑用于两个渐变,因为第一个id具有 display:none 它不会渲染。

更改顺序将使您的代码工作,因为第一个将不再具有 显示:无

.mobile{
显示:无;
}

.content svg{
边框:1px纯黑;
}

<div class="desktop">
  <!-- stuff here -->
</div>
<div class="content">
  <svg class="content-svg" height="150" width="400">
  <defs>
    <linearGradient id="grad1" x1="0%" y1="0%" x2="100%" y2="0%">
      <stop offset="0%" style="stop-color:rgb(255,255,0);stop-opacity:1" />
      <stop offset="100%" style="stop-color:rgb(255,0,0);stop-opacity:1" />
    </linearGradient>
  </defs>
  <ellipse cx="200" cy="70" rx="85" ry="55" fill="url(#grad1)" />
