当用户将鼠标悬停在导航栏上时，我的导航栏上有 CSS 动画。

问题是它们都只能在 Chrome 中工作。他们都有正确的扩展名但没有任何反应？

一个按钮的示例：

#WhatsWhatButton:hover
{
-webkit-animation-name: sway;
-webkit-animation-duration: 1.5s;
-webkit-animation-fill-mode: both;
-moz-animation-name: sway;
-moz-animation-duration: 1.5s;
-moz-animation-fill-mode: both;
-ms-animation-name: sway;
-ms-animation-duration: 1.5s;
-ms-animation-fill-mode: both;
-o-animation-name: sway;
-o-animation-duration: 1.5s;
-o-animation-fill-mode: both;
animation-name: sway;
animation-duration: 1s;
animation-fill-mode: both;
} 

@-webkit-keyframes sway
{
0% {background:url('Images/Icons/WhatsWhatIcon.png'); background-position: center bottom;background-size: 225px 100px;}

如您所见，所有关键帧都有它们的扩展名，并且是从内部启动的#WhatsWhatsButton:hover

然而，它仍然没有在 IE 或 Firefox 中设置动画。

作为记录，我正在运行最新的 Firefox (V22.0) 和 IE 10

Firefox 和 IE10 都支持 CSS 动画（现在甚至没有前缀，所以没有必要为动画使用 -ms- 前缀，因为没有发布的 IE 版本需要它们，而且 -moz- 可能也可以安全删除，因为 Firefox 没有'从版本 16 开始不需要前缀）。但是“背景图像”属性在规范中被标记为“不可动画”。这就是为什么大多数浏览器不能通过 CSS 动画（交叉淡入淡出）它们，只有 Chrome 有这个非标准功能。有关该主题的更多信息：Firefox 的背景图像的 CSS3 转换不起作用

作为一种解决方法，我建议创建 2 层背景（例如元素和伪元素）并为顶层的不透明度设置动画。
