如何使用HTML5 CSS3创建无限文本列表滚动器垂直循环以及是否使用JavaScript

如何解决如何使用HTML5 CSS3创建无限文本列表滚动器垂直循环以及是否使用JavaScript

当您向下滚动到网站并到达RFQ请求报价部分右侧表单区域时，我想要一个类似于Alibaba.com主页上的动画。作为参考，请在网站的该部分附加图片。

我尝试过此代码：

.rfq-scroll-main
{
    Box-sizing: content-Box;
    color: #333;
    font-size: 16px;
    font-family: 'Roboto',sans-serif;
    display: inline-block;
    position: relative;
    
}

.rfq-list-scroll-wrapper
{
    width: 608px;
    height: 30px;
    margin: 25px 0;
    margin-top: 25px;
    margin-right: 0px;
    margin-bottom: 25px;
    margin-left: 0px;
    position: relative;
    vertical-align: baseline;
    display: inline-block;
    color: #333;
    font-family: 'Roboto',sans-serif;
    background: transparent;
}
.rfq-list
{
    height: 30px;
    overflow: hidden;
    display: inline-block;
}

.rfq-list div span
{
    padding: -4px 15px 10px 15px;
    height: 30px;
    margin-bottom: 32px;
    display: inline-block;
}

.rfq-list div span:first-child
{
    animation: scroll 25s infinite;
}

@keyframes scroll
{
    0% 
    {
        transform: translateY(0);
    }

}

<div class="rfq-scroll-main">
     <div class="rfq-list-scroll-wrapper">

           </div>
       </div>
  </div>

我执行的这段代码一次显示了两个div，并且看不到它们的动画方式

请帮助

解决方法

这是一个动画关键帧序列问题，我花了一些时间并能够对其进行正确配置。

此处是正确的代码：

.rfq-scroll-main
{
    box-sizing: content-box;
    color: #333;
    font-size: 16px;
    font-family: 'Roboto',sans-serif;
    display: inline-block;
    position: relative;
    
}

.rfq-list-scroll-wrapper
{
    width: 608px;
    height: 30px;
    margin: 25px 0;
    margin-top: 25px;
    margin-right: 0px;
    margin-bottom: 25px;

}
.rfq-list
