CSS 关键帧仅适用于 Chrome

Question

我正在尝试使用关键帧制作一个简单的动画，但它仅适用于 Chrome。这是代码(为了更短的帖子，我只包含一次关键帧代码):

@keyframes logokf {
    0% {
    background-image: url('gfx/logo1.png');
    }    
    20% {
    background-image: url('gfx/logo2.png');
    }    
    40% {
    background-image: url('gfx/logo3.png');
    }    
    60% {
    background-image: url('gfx/logo4.png');
    }    
    80% {
    background-image: url('gfx/logo1.png');
    }    
    100% {
    background-image: url('gfx/logo1.png');
    }

}


@-webkit-keyframes logokf {    
}

@-moz-keyframes logokf {             
}

@-o-keyframes logokf { 
}

@-ms-keyframes logokf {
}

#logo:hover {
float: left;
height: 75px;
margin: 28px 0 22px;
width: 276px;

/*animation-name*/
-webkit-animation-name:logokf;
-moz-animation-name:logokf;
-ms-animation-name:logokf;
-o-animation-name:logokf;
animation-name:logokf;

/*animation-duration*/
-webkit-animation-duration:1s;
-moz-animation-duration:1s;
-ms-animation-duration:1s;
-o-animation-duration:1s;
animation-duration:1s;

/*animation-iteration-count*/
-webkit-animation-iteration-count:infinite;
-moz-animation-iteration-count:infinite;
-ms-animation-iteration-count:infinite;
-o-animation-iteration-count:infinite;
animation-iteration-count:infinite;

/*animation-timing-function*/
-webkit-animation-timing-function:lineare;
-moz-animation-timing-function:lineare;
-ms-animation-timing-function:lineare;
-o-animation-timing-function:lineare;
animation-timing-function:lineare;

/*animation-delay*/
-webkit-animation-delay:0s;
-moz-animation-delay:0s;
-ms-animation-delay:0s;
-o-animation-delay:0s;
animation-delay:0s;

 }

有什么想法可以解决这个问题，或者其他浏览器尚不支持关键帧？

背景图像本身似乎不是 a valid transitionable property.它可能碰巧在 Chrome 中工作，但这可能只是运气好。实现后，您将希望使用 crossfade capability在 CSS 图像中。
