html - 幻灯片动画的问题

Question

我是一名 CSS 经验不多的开发人员。我想使用两张图片创建一个纯 CSS3 幻灯片。我找到了 some nifty code为此，我在下面实现了一个非常小的变化(基本上我只是取出了 #cf3 id 选择器 img .top ):

.slide {
    position:absolute;
}   

@keyframes cf3FadeInOut {
    0% {
          opacity:1;

}           
45% {
    opacity:1;

}           
55% {       
    opacity:0;

}       
100% {  
    opacity:0;

}       

}

img.top {
    animation-name: cf3FadeInOut;
    animation-timing-function: ease-in-out;
    animation-iteration-count: infinite;
    animation-duration: 10s;
    animation-direction: alternate;

}

第一张图片定义为<img class="slideshow top" src="img1.jpg"> .第二个是相同的，只是没有 "top"类(class)。

当我加载该页面时，我的所有其他 CSS 都能正常工作，但找不到动画。有人看到我哪里出错了吗？

您需要添加供应商特定的属性名称，CSS3 animation仍然是规范草案。

-webkit-animation-name: cf3FadeInOut;
-webkit-animation-timing-function: ease-in-out;
-webkit-animation-iteration-count: infinite;
-webkit-animation-duration: 10s;
-webkit-animation-direction: alternate;

-moz-animation-name: cf3FadeInOut;
-moz-animation-timing-function: ease-in-out;
-moz-animation-iteration-count: infinite;
-moz-animation-duration: 10s;
-moz-animation-direction: alternate;

-o-animation-name: cf3FadeInOut;
-o-animation-timing-function: ease-in-out;
-o-animation-iteration-count: infinite;
-o-animation-duration: 10s;
-o-animation-direction: alternate;

animation-name: cf3FadeInOut;
animation-timing-function: ease-in-out;
animation-iteration-count: infinite;
animation-duration: 10s;
animation-direction: alternate;

/* and all the keyframes too */
@-webkit-keyframes cf3FadeInOut { ... }
@-moz-keyframes cf3FadeInOut { ... }
@-o-keyframes cf3FadeInOut { ... }
@keyframes cf3FadeInOut { ... }
