如何 SVG图像用内

Question

我想将Telegram SVG icon导入一个带有<symbol>标签和多个<use>标签的网页。问题是当我尝试以下方法时图标被破坏：

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    Here is an icon:

    <!-- SVG Definition -->

    <svg style="display: none" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
      <defs>
        <linearGradient id="b" x1="0.6667" y1="0.1667" x2="0.4167" y2="0.75">
          <stop stop-color="#37aee2" offset="0"/>
          <stop stop-color="#1e96c8" offset="1"/>
        </linearGradient>
        <linearGradient id="w" x1="0.6597" y1="0.4369" x2="0.8512" y2="0.8024">
          <stop stop-color="#eff7fc" offset="0"/>
          <stop stop-color="#fff" offset="1"/>
        </linearGradient>
      </defs>  
      <symbol id="telegram-icon" viewBox="0 0 240 240">
        <circle cx="120" cy="120" r="120" fill="url(#b)"/>
        <path fill="#c8daea" d="m98 175c-3.8876 0-3.227-1.4679-4.5678-5.1695L82 132.2059 170 80"/>

      </symbol>
    </svg>

    <!-- SVG Usage -->

    <svg><use href="#telegram-icon"></use></svg>
    <br/>
    <a href="https://commons.wikimedia.org/wiki/File:Telegram_logo.svg">Source of the image</a>
  </body>
</html>

也在codepen.io。

为什么它会被破坏以及如何修复上面的代码以允许在网页上重用SVG图标？

Final Solution

<svg style="width: 0; height: 0; position: absolute;"...>

即使添加了零宽度和高度<svg>仍然正在发生，添加position: absolute解决了这个问题。
