internet-explorer - 为什么这个渐变在 IE 9 上不起作用？

Question

CSS:

 background-image: linear-gradient(bottom, #000000 29%, #999999 65%);
    background-image: -o-linear-gradient(bottom, #000000 29%, #999999 65%);
    background-image: -moz-linear-gradient(bottom, #000000 29%, #999999 65%);
    background-image: -webkit-linear-gradient(bottom, #000000 29%, #999999 65%);
    background-image: -ms-linear-gradient(bottom, #000000 29%, #999999 65%);
    background-image: -webkit-gradient(linear,  left bottom,    left top,   color-stop(0.29, #000000),  color-stop(0.65, #999999));
    filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#000000', endColorstr='#999999');

为什么 IE 版本的渐变不起作用？我似乎找不到问题所在？

Answer 1

尝试设置 GradientType 属性:

filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#000000', endColorstr='#999999', GradientType=0);
