CSS中的多个图像交叉淡入淡出 - 没有(java)脚本

Question

是否可以在CSS中交叉淡化5个图像,而不使用java脚本？我发现了一个类似的问题: css3图像交叉淡入淡出(没有javascript),但是,它只有CSS代码片段; 我试过,但无法让它工作.我是CSS的新手,所以无法将上面提到的CSS链接到我的下面的HTML:

  <div id= "crossfade">
     <img class = "cone" src = "1.png" alt = "png">
     <img class = "ctwo" src = "2.png" alt = "png">
     <img class = "cthree" src = "3.png" alt = "png">
     <img class = "cfour" src = "4.png" alt = "png">
     <img class = "cfive" src = "5.png" alt = "png">
  </div>

如果您知道有多少图像,可以使用CSS3轻松完成.

jsFiddle:http://jsfiddle.net/hajmd/

#crossfade > img { 
    width: 100%;
    height: 100%;
    position: absolute;
    top: 0px;
    left: 0px;
    color: transparent;
    opacity: 0;
    z-index: 0;
    -webkit-backface-visibility: hidden;
    -webkit-animation: imageAnimation 30s linear infinite 0s;
    -moz-animation: imageAnimation 30s linear infinite 0s;
    -o-animation: imageAnimation 30s linear infinite 0s;
    -ms-animation: imageAnimation 30s linear infinite 0s;
    animation: imageAnimation 30s linear infinite 0s; 
}

" -webkit-animation:imageAnimation 30s linear infinite 0s; "中的" 30s "表示每个图像的动画将以infinete次数持续30秒.

#crossfade > img:nth-child(2)  { 
    background-image: url(../images/2.jpg);
    -webkit-animation-delay: 6s;
    -moz-animation-delay: 6s;
    -o-animation-delay: 6s;
    -ms-animation-delay: 6s;
    animation-delay: 6s; 
}
#crossfade > img:nth-child(3) { 
    background-image: url(../images/3.jpg);
    -webkit-animation-delay: 12s;
    -moz-animation-delay: 12s;
    -o-animation-delay: 12s;
    -ms-animation-delay: 12s;
    animation-delay: 12s; 
}
#crossfade > img:nth-child(4) { 
    background-image: url(../images/4.jpg);
    -webkit-animation-delay: 18s;
    -moz-animation-delay: 18s;
    -o-animation-delay: 18s;
    -ms-animation-delay: 18s;
    animation-delay: 18s; 
}
#crossfade > img:nth-child(5) { 
    background-image: url(../images/5.jpg);
    -webkit-animation-delay: 24s;
    -moz-animation-delay: 24s;
    -o-animation-delay: 24s;
    -ms-animation-delay: 24s;
    animation-delay: 24s; 
}
