CSS3实现轮播图效果2

先前用CSS3做了一个一张图片实现的轮播，但是这样的图片很难找，于是又改进了一下。

HTML：

<span style="color: #0000ff;"><span style="color: #800000;">div </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="box"</span><span style="color: #0000ff;">></span>
    <span style="color: #0000ff;"><span style="color: #800000;">ul</span><span style="color: #0000ff;">></span>
        <span style="color: #0000ff;"><span style="color: #800000;">li</span><span style="color: #0000ff;">></span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span>
        <span style="color: #0000ff;"><span style="color: #800000;">li</span><span style="color: #0000ff;">></span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span>
        <span style="color: #0000ff;"><span style="color: #800000;">li</span><span style="color: #0000ff;">></span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span>
        <span style="color: #0000ff;"><span style="color: #800000;">li</span><span style="color: #0000ff;">></span><span style="color: #800000;">li</span><span style="color: #0000ff;">></span>
    <span style="color: #0000ff;"></span><span style="color: #800000;">ul</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">div</span><span style="color: #0000ff;">></span></span></span></span></span></span></span>

CSS：

        .box ul li</span>{<span style="color: #ff0000;">

            background-color</span>:<span style="color: #0000ff;"> #F00</span>;
        }<span style="color: #800000;">
        .box ul li:nth-of-type(4)</span>{<span style="color: #ff0000;">
            background-color</span>:<span style="color: #0000ff;"> #000</span>;
        }<br><br><span style="color: #800000;"></span>

原理和上次轮播差不多，让ul改变位置。轮播图片，在li里放图片即可。
