Let me give you a rendering first. It seems simple, but actually it is very simple to implement. It is simple and practical

The fonts in the black box will automatically scroll to form a scroll bar, which can be used for display and prompts. First, we need to write the text we want in the body. For example, I want to write: If you feel good, please click to recommend

<body>
        <div id=<span style="color: #800000;">"</span><span style="color: #800000;">div</span><span style="color: #800000;">"</span>>
        <ul id=<span style="color: #800000;">"</span><span style="color: #800000;">ul</span><span style="color: #800000;">"</span>>
            <li>感</li>
            <li>觉</li>
            <li>好</li>
            <li>的</li>
            <li>请</li>
            <li>点</li>
            <li>击</li>
            <li>推</li>
            <li>荐</li>
        </ul>
        </div>
    </body>

Next we adjust the style in the style to realize its scrolling

<span style="color: #800000;"><style><br>　　/*先给个整体去除下划线*/
        ul,li,ol</span>{<span style="color: #ff0000;">
            list-style</span>:<span style="color: #0000ff;"> none</span>;
        }<br>　　<br><span style="color: #800000;">/*这里也就是重点喽，时间分段，到还没滚动的时候时间经过了0%所以left也就为0，当开始滚动时间停止的时候那么就等于全部完成也就是100%，这句话写不对效果就不出哦*/
        @-webkit-keyframes move </span>{<span style="color: #ff0000;">
                0% {
                    left</span>:<span style="color: #0000ff;"> 0</span>;
                }<span style="color: #800000;">
                100% </span>{<span style="color: #ff0000;">
                    left</span>:<span style="color: #0000ff;"> -400px</span>;
                }<span style="color: #800000;">
            }
       <br>/*以下是布局样式*/  
        #div</span>{<span style="color: #ff0000;">
            width</span>:<span style="color: #0000ff;"> 500px</span>;<span style="color: #ff0000;">
            height</span>:<span style="color: #0000ff;"> 100px</span>;<span style="color: #ff0000;">
            margin</span>:<span style="color: #0000ff;"> 100px auto</span>;<span style="color: #ff0000;">

            padding</span>:<span style="color: #0000ff;"> 0</span>;<span style="color: #ff0000;">
            margin-top</span>:<span style="color: #0000ff;"> 0px</span>;<span style="color: #ff0000;">    
            width</span>:<span style="color: #0000ff;"> 185%</span>;<span style="color: #ff0000;">
            display</span>:<span style="color: #0000ff;"> block</span>;<br>/*这句话也是至关重要的，少了这句话也不会滚动，我给他四个值，3s代表三秒之内完成滚动，move这个名字对应着上面时间分段的名字，infinite代表循环滚动，linear表示匀速滚动*/<br><span style="color: #ff0000;">
            -webkit-animation</span>:<span style="color: #0000ff;"> 3s move infinite linear</span>;
        }<span style="color: #800000;">
        #ul li</span>{<span style="color: #ff0000;">
            float</span>:<span style="color: #0000ff;"> left</span>;<span style="color: #ff0000;">

            margin-left</span>:<span style="color: #0000ff;"> 1px</span>;<span style="color: #ff0000;">

        }
        
        
        <span style="color: #008000;">/*这句话代表鼠标移动上去滚动会</span><span style="color: #008000;">停止，类似于轮播</span><span style="color: #008000;">*/</span><span style="color: #800000;">
        #div:hover #ul </span>{<span style="color: #ff0000;">
