IE9 SVG渐变不起作用

Question

我使用Microsoft 渐变生成器生成以下内容：

div.footer
{
    background-image:url(data:image/svg+xml;base64,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); 
}

当我检查DOM时，它似乎起作用了，但页面上没有看到任何渐变。 我应该设定其他吗？

那你的DocType呢？ 您是否已将网页声明为HTML5 / SVG？
