div中的渐变和背景图像

Question

我有一个设置，我在我的div中使用渐变和背景图像。 问题是我希望它适用于所有的浏览器。不知道我将如何使这项工作。通常我会做一个混合，并以我的风格包含它。这将是我没有图像背景的代码。

background: #ffffff; /* Old browsers */
/* IE9 SVG, needs conditional override of 'filter' to 'none' */
background: url(data:image/svg+xml;base64,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);
background: -moz-linear-gradient(top,  #ffffff 0%, #ffffff 50%, #f9f9f9 51%, #efefef 99%); /* FF3.6+ */
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ffffff), color-stop(50%,#ffffff), color-stop(51%,#f9f9f9), color-stop(99%,#efefef)); /* Chrome,Safari4+ */
background: -webkit-linear-gradient(top,  #ffffff 0%,#ffffff 50%,#f9f9f9 51%,#efefef 99%); /* Chrome10+,Safari5.1+ */
background: -o-linear-gradient(top,  #ffffff 0%,#ffffff 50%,#f9f9f9 51%,#efefef 99%); /* Opera 11.10+ */
background: -ms-linear-gradient(top,  #ffffff 0%,#ffffff 50%,#f9f9f9 51%,#efefef 99%); /* IE10+ */
background: linear-gradient(top,  #ffffff 0%,#ffffff 50%,#f9f9f9 51%,#efefef 99%); /* W3C */ 

现在我可以让一个渐变起作用但是对于所有其他broswers如何。

        background: url("/images/icons.png") no-repeat scroll 0 -440px,  -moz-linear-gradient(top,  #ffffff 0%, #ffffff 50%, #f9f9f9 51%, #efefef 99%);

另外，IE9 SVG和png一起如何工作。
