Question

当用户将鼠标悬停在我的导航栏上时，我会使用CSS动画。

问题是它们都只能在Chrome中运行。它们都有正确的扩展但没有任何反应？

ONE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;}
15% {background:url('Images/Icons/WhatsWhatIcon2.png'); background-position: center bottom;background-size: 225px 100px;}

正如您所看到的，所有关键帧都有自己的扩展，并在#WhatsWhatsButton:hover

内启动它

但它仍然没有在IE或Firefox中制作动画。

为了记录，我正在运行最新的Firefox（V22.0）和IE 10

Answer 1

Firefox和IE10都支持CSS动画（现在甚至没有固定，因此没有真正需要使用-ms-前缀用于动画，因为没有发布需要它们的IE版本，并且-moz-可能也是安全的删除因为自16版以来Firefox并不需要一个前缀。但是＆＃39; background-image＆＃39;属性在规范中标记为“不可动画”。这就是为什么大多数浏览器都可以通过CSS动画（交叉淡化）它们的原因，只有Chrome具有这种非标准功能。有关该主题的更多信息：CSS3 transition of background-image for Firefox not working

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。

Firefox和IE中的CSS动画支持？
