CSS3 implements carousel effect 2

I used CSS3 to create a carousel one by one, but it was hard to find such pictures, so I improved it again.

HTML:

<span style="color: #0000ff;"><</span><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><span style="color: #800000;">ul</span><span style="color: #0000ff;">></span>
        <span style="color: #0000ff;"><</span><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;">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;">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;">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>

CSS:

<span style="color: #800000;"><style>
        .box</span>{<span style="color: #ff0000;">
            position</span>:<span style="color: #0000ff;"> relative</span>;<span style="color: #ff0000;">

        }<span style="color: #800000;">
        div ul</span>{<span style="color: #ff0000;">

        }<span style="color: #800000;">
        @keyframes lb </span>{<span style="color: #ff0000;">
            0%{

            }<span style="color: #800000;">
            25%</span>{<span style="color: #ff0000;">
                left</span>:<span style="color: #0000ff;"> -100%</span>;
            }<span style="color: #800000;">
            50%</span>{<span style="color: #ff0000;">
                left</span>:<span style="color: #0000ff;"> -200%</span>;
            }<span style="color: #800000;">
            75%</span>{<span style="color: #ff0000;">

            }<span style="color: #800000;">
        }
        .box ul li</span>{<span style="color: #ff0000;">
            float</span>:<span style="color: #0000ff;"> left</span>;<span style="color: #ff0000;">
            height</span>:<span style="color: #0000ff;"> 100%</span>;<span style="color: #ff0000;">
            list-style</span>:<span style="color: #0000ff;"> none</span>;<span style="color: #ff0000;">
            width</span>:<span style="color: #0000ff;"> 25%</span>;
        }<span style="color: #800000;">
        .box ul li:nth-of-type(1)</span>{<span style="color: #ff0000;">

            background-color</span>:<span style="color: #0000ff;"> #FEA</span>;
        }<span style="color: #800000;">
        .box ul li:nth-of-type(3)</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;"></style></span>

The principle is similar to the last carousel, let ul change its position. To carousel pictures, just put pictures in li.
