只有经受过冰霜的人，才会领悟太阳的温暖，只有饱尝人生艰辛的人，才会懂得生命的可贵。早安！

本文实例为大家分享了vue3实现CSS无限无缝滚动效果的具体代码，供大家参考，具体内容如下

template

双层div嵌套，进行隐藏滚动显示

<div class="list-container">
  <div class="marquee" id="carList">
    <template v-for="(item, index) in dataMap.list" :key="index">
      <div class="list-item">
        <div class="item-name text-overflow">{{ item.name }}</div>
        <div class="item-road text-overflow">{{ item.road }}</div>
      </div>
    </template>
  </div>
</div>

script

复制dom元素中的内容，衔接上一次滚动效果

export default defineComponent({
  setup() {
    const dataMap = reactive({
      list: [
        { name: '浙A89268', road: '游8路', status: 0 },
        { name: '浙A89268', road: '游8路', status: 0 },
        { name: '浙A89268', road: '游8路', status: 1 },
        { name: '浙A89268', road: '游8路', status: 0 },
        { name: '浙A89268', road: '游8路', status: 1 },
        { name: '浙A89268', road: '游1路', status: 0 },
      ],
    });
    onMounted(() => {
      const marquee = document.getElementById('carList');
      marquee.innerHTML = marquee.innerHTML + marquee.innerHTML;
    });
  }
})

style

CSS手写动画效果

.list-container {
  width: 720px;
  height: 170px;
  margin-left: 13px;
  overflow: hidden;
  position: relative;
}
//无限滚动
.marquee {
  //animation-delay: -5s;
  animation: marquee 15s linear infinite;
}
.marquee:hover {
  animation-play-state: paused;
}
@keyframes marquee {
  0% {
    transform: translateY(0%);
  }
  100% {
    transform: translateY(-51%); //这里不是-100%！
  }
}
