CSS3实现轮播图主要是由css:background-position和css3:animation实现。且实现此轮播需要一张四个图横着相连的图片。
注(Internet Explorer 10、Firefox 以及 Opera 支持 animation 属性。Safari 和 Chrome 支持替代的 -webkit-animation 属性。)
HTML:
<span style="color: #0000ff;"><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="slide-box"</span><span style="color: #0000ff;">></span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span></span>
CSS:
<span style="color: #800000;"><style> @-webkit-keyframes slide </style></span>{<span style="color: #ff0000;"> 0% { background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> 10%, 25% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -600px 0</span>; }<span style="color: #800000;"> 35%, 50% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1200px 0</span>; }<span style="color: #800000;"> 60%, 75% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1800px 0</span>; }<span style="color: #800000;"> 85%, 100% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> } @-moz-keyframes slide </span>{<span style="color: #ff0000;"> 0% { background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> 10%, 25% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -600px 0</span>; }<span style="color: #800000;"> 35%, 50% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1200px 0</span>; }<span style="color: #800000;"> 60%, 75% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1800px 0</span>; }<span style="color: #800000;"> 85%, 100% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> } @-o-keyframes slide </span>{<span style="color: #ff0000;"> 0% { background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> 10%, 25% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -600px 0</span>; }<span style="color: #800000;"> 35%, 50% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1200px 0</span>; }<span style="color: #800000;"> 60%, 75% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1800px 0</span>; }<span style="color: #800000;"> 85%, 100% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> } @keyframes slide </span>{<span style="color: #ff0000;"> 0% { background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> 10%, 25% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -600px 0</span>; }<span style="color: #800000;"> 35%, 50% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1200px 0</span>; }<span style="color: #800000;"> 60%, 75% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> -1800px 0</span>; }<span style="color: #800000;"> 85%, 100% </span>{<span style="color: #ff0000;"> background-position</span>:<span style="color: #0000ff;"> 0 0</span>; }<span style="color: #800000;"> } .slide-box </span>{<span style="color: #ff0000;"> margin</span>:<span style="color: #0000ff;"> 0 auto</span>;<span style="color: #ff0000;"> width</span>:<span style="color: #0000ff;"> 600px</span>;<span style="color: #ff0000;"> height</span>:<span style="color: #0000ff;"> 400px</span>;<span style="color: #ff0000;"> border</span>:<span style="color: #0000ff;"> 1px solid #ddd</span>;<span style="color: #ff0000;"> background</span>:<span style="color: #0000ff;"> url(http://sandbox.runjs.cn/uploads/rs/376/uazzmdfd/bg.png) 0 0 no-repeat</span>;<span style="color: #ff0000;"> -webkit-animation</span>:<span style="color: #0000ff;"> slide 8s linear infinite</span>;<span style="color: #ff0000;"> -o-animation</span>:<span style="color: #0000ff;"> slide 8s linear infinite</span>;<span style="color: #ff0000;"> animation</span>:<span style="color: #0000ff;"> slide 8s linear infinite</span>; }<span style="color: #800000;"> </span>
animation 属性是一个简写属性,JavaScript 语法: object.style.animation=" slide 8s linear infinite",其参数如下:
animation-name | 规定需要绑定到选择器的 keyframe 名称。。 |
animation-duration | 规定完成动画所花费的时间,以秒或毫秒计。 |
animation-timing-function | 规定动画的速度曲线。 |
animation-delay | 规定在动画开始之前的延迟。 |
animation-iteration-count | 规定动画应该播放的次数。 |
animation-direction |
规定是否应该轮流反向播放动画。 |
让图片在8秒内进行位移,每次向左移动600px,最后回到原点,div宽600px,刚好容下一个图,这样就构成了轮播效果。
