Question

是否有一种简单的方法，仅使用CSS来启用背景图片幻灯片？我将背景图像定义为全屏并在CSS中的html属性内响应，并希望它具有简单的过渡效果。 CSS看起来像这样：

＆＃13;

html {
	background: url(slike/bg.jpg) no-repeat center fixed;
	-webkit-background-size: cover;
	-moz-background-size: cover;
	-o-background-size: cover;
	background-size: cover;
}

＆＃13;

我是否需要在html中定义它并创建一个新的CSS类？唯一的问题是＆＃39;是背景需要全屏和响应。

您可以使用像

这样的容器div来实现

＆＃13;

html,body {

  width:100%;
  height:100%;
}
body {
 margin: 0;
}
.container 
{
width:100%;
height:100%;
}
#slideshow {
  list-style: none;
  margin: 0;
  padding: 0;
  position: relative;
  width:100%;
  height:100%;
  display: inline-block;
}
.elemnt,.elemnt1,.elemnt2,.elemnt3 {
position: absolute;
left: 0;
width: 100%;
background-repeat: no-repeat;
background-size: cover;
height: 100%;
display: inline-block;
text-align: center;
}
span{
  border: 1px solid #000;
  border-radius: 3px;
  box-shadow: 0 0 5px 0 hsla(0,0%,30%, .3);
  font-size:4em;
  background-color:#fff
}
.elemnt {
  animation: xfade 16s 8s infinite;
  background-image: url('http://desert-maroc.com/wordpress2012/wp-content/uploads/trek-sahara-sauvage-min.jpg');
}
.elemnt1 {
  animation: xfade 16s 6s infinite;
  background-image: url('http://desert-maroc.com/wordpress2012/wp-content/uploads/sahara-desert-by-ellie-1024x683.jpg');
  
}
.elemnt2 {
  animation: xfade 16s 2s infinite;
  background-image: url('https://pbs.twimg.com/media/C4JYsjcWYAAixfx.jpg');
}
.elemnt3 {
  animation: xfade 16s 0s infinite;
  background-image: url('http://desert-maroc.com/wordpress2012/wp-content/uploads/trek-sahara-sauvage-min.jpg');
  
}
@keyframes xfade{
  17% {
    opacity:1;
  }
  25% {
    opacity:0;
  }
  92% {
    opacity:0;
  }
}
@keyframes xfade1{
  17% {
    opacity:1;
  }
  25% {
    opacity:0;
  }
  92% {
    opacity:0;
  }
}
@keyframes xfade2{
  17% {
    opacity:1;
  }
  25% {
    opacity:0;
  }
  92% {
    opacity:0;
  }
}
@keyframes xfade3{
  17% {
    opacity:1;
  }
  25% {
    opacity:0;
  }
  92% {
    opacity:0;
  }
}

＆＃13;

<div class="container">
   <div id="slideshow">
  <div class="elemnt"><span>Text Slider 1</span></div>
  <div class="elemnt1"><span>Text Slider 2</span></div>
  <div class="elemnt2"><span>Text Slider 3</span></div>
  <div class="elemnt3"><span>Text Slider 4</span></div>
  </div>
</div>

＆＃13;

现在尝试使用滑块仅使用css，您可以通过更改动画持续时间来修改时间
