使用SVG Base64 URI的CSS光标图像

因此，我将这个SVG元素编码为Base64：

但是这个特定的版本data:image/svg+xml似乎不起作用。如果我使用它作为背景，它会，但我似乎无法让它为光标工作

有什么想法或见解可以解释为什么这不起作用吗？

您使用的是哪种web浏览器？您的代码在Google Chrome中运行良好

根据目前的规范，它也应该在Firefox中工作

---

我猜你正在使用Internet Explorer？根据IEAT的文档，

游标：url（uri）属性必须是.cur或.ani文件。它看起来不支持SVG游标，除了通过SVGCursorElement在SVG文件中（有关详细信息，请参阅）。
Hmmm。。。可能是我的dom元素没有任何宽度或高度的问题。谢谢你的精神检查。很高兴知道我在正确的轨道上。：）
