Internet Explorer的径向渐变

Question

我正在尝试用纯css3做动画。动画是从左到右移动的眼睛，我的问题是我使用径向渐变背景的眼睛，但在Internet Explorer上这种效果看起来不起作用，但在Chrome和Firefox上运行良好。

您可以在此处查看演示：http://jsfiddle.net/h6VYd/

这里是css代码：

body {

}

.ball {
  display: inline-block;

  height: 100%;
  margin: 0;

  background: -webkit-radial-gradient(50% 40%, circle cover, #fcfcfc, #efeff1 66%, #9b5050 100%);

Answer 1

您需要添加-ms-radial-gradient CSS声明。

例如：

background: -ms-radial-gradient(50% 40%, circle cover, #fcfcfc, #efeff1 66%, #9b5050 100%);

这是工作jsFiddle。
