Pure CSS Slider

Question

所以我开始熟悉css3，我一直在尝试寻找一个纯粹的css滑块。我终于找到了一个和我在代码笔上寻找的完全一样的代码，但由于某种原因，当我在localhost或jsfiddle中尝试代码时，它不起作用。据我在codepen中所知，它没有访问的外部文件，也不需要jQuery。下面我链接了（正在工作的）codepen和jsfiddle。有什么想法为什么它在其他地方不起作用吗？

css

body{background:#000;}
.slider{
  margin:50px auto;
  width:100%;
  height:300px;
  overflow:hidden;
  position:relative;
}
.photo{
  position:absolute;
  animation:round 16s infinite;
  opacity:0;
  width:100%;
}
@keyframes round{   
  25%{opacity:1;}
  40%{opacity:0;}
} 
img:nth-child(4){animation-delay:0s;}
img:nth-child(3){animation-delay:4s;}
img:nth-child(2){animation-delay:8s;}
img:nth-child(1){animation-delay:12s;}

您可能需要使用特定于供应商的keyframes。Codepen很聪明，在这种情况下补偿过度。

@-webkit-keyframes NAME-YOUR-ANIMATION {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}
@-moz-keyframes NAME-YOUR-ANIMATION {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}
@-o-keyframes NAME-YOUR-ANIMATION {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}
@keyframes NAME-YOUR-ANIMATION {
  0%   { opacity: 0; }
  100% { opacity: 1; }
}

这非常有效，请检查：jsFiddle Demo。代码中使用的CSS3动画和关键帧的语法是标准语法，例如animation:round 16s infinite;、@keyframes round{ 25%{opacity:1;} 40%{opacity:0;} }和img:nth-child(4){animation-delay:0s;}。

您应该使用-webkit-animation:round 16s infinite;`, `@-webkit-keyframes round{ 25%{opacity:1;} 40%{opacity:0;} } ` and `img:nth-child(4){-webkit-animation-delay:0s;}，以便它与浏览器兼容。
