纯 css 每3秒播一张图片。9s是总共时间,如果是4张图片这里写 12s
完全可以,用css的重复播放动画的功能实现自动切换。
做了个小例子,你可以看看,基本的思路就这样了,效果还比较不错啦。这个思路还可以用来作为图片滚动播放的例子呢。
body部分代码:
<body>
<div id="box1">
<div id="box2">
<img src="https://www.baidu.com/img/bd_logo1.png">
<img src="https://www.baidu.com/img/bd_logo1.png">
<img src="https://www.baidu.com/img/bd_logo1.png">
<img src="https://www.baidu.com/img/bd_logo1.png">
</div>
</div>
</body>
css的代码:
*{
padding:0
margin:0
}
html,body{
overflow-x:hidden
overflow-y:auto
}
#box1{
position:relative
width:500px
height:450px
margin:0 auto
background:red
overflow:hidden
}
#box2{
float:left
width:2000px
height:450px
animation:box2 2s both linear infinite
-webkit-animation:box2 2s both linear infinite/* Safari and Chrome */
}
#box2:hover {
animation-play-state: paused
}
@keyframes box2
{
from {
margin-left:0
}
to {
margin-left:-1500px
}
}
@-webkit-keyframes myfirst /* Safari and Chrome */
{
from {
margin-left:0
}
to {
margin-left:-1500px
}
}
img{
float:left
width:500px
height:450px
}

好像时间间隔设置太短了,可以把动画播放的时间延长一点。
首先 写多个背景的class比如
.imgA {background: url(demo1.jpg) no-repeat}
.imgB {background: url(demo2.jpg) no-repeat}
....
然后在需要切换背景的层上用js替换class就行
