纯CSS滑块

Question

所以我熟悉了css3，我一直试图找到一个纯粹的css滑块。我终于找到了一个与我在代码笔上寻找的完全相同但由于某种原因，当我在localhost或jsfiddle中尝试代码时，它不起作用。在codepen中没有外部文件可以访问，并且不需要jQuery。下面我链接了（工作）codepen和jsfiddle。任何想法为什么它不会在其他地方工作？

HTML

<div class="slider">
  <img class='photo'  src="http://i.imgur.com/zMGSiyl.jpg" alt="" />
  <img class='photo'  src="http://i.imgur.com/soQhb13.jpg" alt="" />
  <img class='photo'  src="http://i.imgur.com/39yOaYB.jpg" alt="" />
  <img class='photo'  src="http://i.imgur.com/tnctKD4.jpg" alt="" />
</div>

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，在这种情况下过度补偿。

@-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; }
}

Answer 2

这完美无缺，请检查： jsFiddle Demo 。 CSS3动画的语法和代码中使用的关键帧是标准语法，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;}以使其与浏览器兼容。
