我用来通过base64 img设置背景渐变，如图所示：

如果您在浏览选项卡中运行它，它看起来像：

<?xml version="1.0" ?>
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 1 1" preserveAspectRatio="none">
  <linearGradient id="grad-ucgg-generated" gradientUnits="userSpaceOnUse" x1="0%" y1="0%" x2="0%" y2="100%">
    <stop offset="0%" stop-color="#f9fcf7" stop-opacity="1"/>
    <stop offset="100%" stop-color="#e6e6e6" stop-opacity="1"/>
  </linearGradient>
  <rect x="0" y="0" width="1" height="1" fill="url(#grad-ucgg-generated)" />
</svg>

我想知道为什么在手机上它不起作用？

正如我所看到的，它适用于每个浏览器的 PC，那么移动设备呢？

我在 Android Galaxy

实际上，您将需要 XML 声明。尝试添加 DOCTYPE，然后对整个 SVG XML 进行编码：

<?xml version="1.0" ?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" viewBox="0 0 1 1" preserveAspectRatio="none">
  <linearGradient id="grad-ucgg-generated" gradientUnits="userSpaceOnUse" x1="0%" y1="0%" x2="0%" y2="100%">
    <stop offset="0%" stop-color="#f9fcf7" stop-opacity="1"/>
    <stop offset="100%" stop-color="#e6e6e6" stop-opacity="1"/>
  </linearGradient>
  <rect x="0" y="0" width="1" height="1" fill="url(#grad-ucgg-generated)" />
</svg>
