使用背景大小的水平渐变条纹在IE9中不起作用

Question

我正在生成一个水平渐变条作为我网站的背景，除了...... IE9之外，它在每个浏览器中都能完美运行。

渐变本身正在工作，只是我想限制蓝条的高度。在Safari / Firefox / Chrome中查看，然后在IE9中查看，蓝色渐变填充整个元素。

Horizontal gradient bar using CSS

这是我的CSS：

#inner {
background: #1e5799;
background: -moz-linear-gradient(top,  #1e5799 0%, #0057be 35%);
background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#1e5799), color-stop(35%,#0057be));
background: -webkit-linear-gradient(top,  #1e5799 0%,#0057be 35%);
background: -o-linear-gradient(top,  #1e5799 0%,#0057be 35%);
background: -ms-linear-gradient(top,  #1e5799 0%,#0057be 35%);
background: linear-gradient(to bottom,  #1e5799 0%,#0057be 35%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#1e5799', endColorstr='#0057be',GradientType=0 );
background-size: 1px 10%;
background-repeat: repeat-x;
margin: 0 auto;
padding: 1em 0;

}

此代码应适用于IE9：

background: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lYXJHcmFkaWVudCBpZD0iZzEiIGdyYWRpZW50VW5pdHM9InVzZXJTcGFjZU9uVXNlIiB4MT0iMCUiIHkxPSIwJSIgeDI9IjAlIiB5Mj0iMTAwJSI+PHN0b3Agb2Zmc2V0PSIwIiBzdG9wLWNvbG9yPSIjMWU1Nzk5Ii8+PHN0b3Agb2Zmc2V0PSIwLjM1IiBzdG9wLWNvbG9yPSIjMDA1N2JlIi8+PC9saW5lYXJHcmFkaWVudD48cmVjdCB4PSIwIiB5PSIwIiB3aWR0aD0iMTAwJSIgaGVpZ2h0PSIxMDAlIiBmaWxsPSJ1cmwoI2cxKSIgLz48L3N2Zz4=);

我用Visual CSS Gradient Generator

更新了CSS：

#inner {
background: #1e5799;
background: url(data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSIxMDAlIiBoZWlnaHQ9IjEwMCUiPjxsaW5lYXJHcmFkaWVudCBpZD0iZzEiIGdyYWRpZW50VW5pdHM9InVzZXJTcGFjZU9uVXNlIiB4MT0iMCUiIHkxPSIwJSIgeDI9IjAlIiB5Mj0iMTAwJSI+PHN0b3Agb2Zmc2V0PSIwIiBzdG9wLWNvbG9yPSIjMWU1Nzk5Ii8+PHN0b3Agb2Zmc2V0PSIwLjM1IiBzdG9wLWNvbG9yPSIjMDA1N2JlIi8+PC9saW5lYXJHcmFkaWVudD48cmVjdCB4PSIwIiB5PSIwIiB3aWR0aD0iMTAwJSIgaGVpZ2h0PSIxMDAlIiBmaWxsPSJ1cmwoI2cxKSIgLz48L3N2Zz4=);

IE9不支持CSS3渐变，但它支持内联SVG。我不建议在IE9上混淆filter和SVG背景，我认为最好的方法是使用条件注释，如this article by Paul Irish中所述。
