CSS3实在是强大， 复杂的动画由CSS来实现着实让人好理解， 闲话不多说直接进入正题。今天实验的不是沉浸式轮播图， 而是类似优酷的立体轮播图

一· 效果演示

这里写图片描述

二· 页面布局

页面布局同正常的轮播图一样没什么好说的。上代码.

<!-- width:500px height:300px -->//我选的图片正常尺寸
    <div class="wrapper">
        <div class="move">
            <img src="1.jpg">
        </div>
        <div class="move">
            <img src="2.jpg">
        </div>
        <div class="move">
            <img src="3.jpg">
        </div>
        <div class="move">
            <img src="4.jpg">
        </div>
        <div class="move">
            <img src="5.jpg">
        </div>
    </div>

三· 思想说明

这里写图片描述

注意到图片到两边时height应该为0， 但是为了视觉效果图片上还是给了一些高度。
总共轮播一共5种状态， 因此一个animation属性要设置0%， 20%， 40%， 60%， 80%， 100%， 这五种状态。 但是由于开始时盒子内已经有三张起始图片因此我认为应该要写4种运动动画， 3个是开始的图片三个， 第4个动画是通用的。每一次的运动就是分别改变left， height， width， 等几种属性。
