如果svg隐藏在单独的类中，则SVG LinearGradient隐藏 [英] SVG LinearGradient hidden if svg is hidden in seperate class

问题描述

基本上，如果svg隐藏在parallell元素中，则将隐藏linearGradient填充

Basically what Is happening is the linearGradient fill is hidden if the svg is hidden in a parallell element

.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)" />

  </svg>
</div>

如您在上面的代码段中所见，SVG元素在那里，linearGradient填充被隐藏

as you can see in the snippet above, the SVG element is there, the linearGradient fill is hidden

如果我将填充更改为CSS中的纯色集，则可以按预期工作，这似乎只在渐变填充中发生

If I change the fill to a solid colour set in my CSS it works as expected, this only seems to happen with gradient fills

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中使用了它，并创建了可重用的svg组件

now this is just a basic example of my overall issue, I want to avoid recreating the SVG since I am using this in Vue and have created a reusable svg component

推荐答案

为渐变选择其他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)" />

  </svg>
</div>

或者如果两个SVG中使用的渐变相同，则仅考虑一个渐变(相关信息:使用SVG符号隐藏的渐变)

Or consider only one gradient if it's the same used in both SVG (related: Gradients hidden using SVG symbols)

.mobile {
  display: none;
}

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

<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)" />

  </svg>
</div>

<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，并且两个渐变仅考虑第一个，并且由于第一个具有display:none，因此不会渲染.

Repeating the same ID is invalid and only the first one will be considered for both gradients and since the first one has display:none it will not render.

更改顺序将使您的代码正常工作，因为第一个不再具有display:none

Changing the order will make your code work because the first one will no more have display:none

.mobile {
  display: none;
}

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

<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)" />
