uniapp小程序中实现无缝衔接滚动效果

组件滚动通知只能实现简单的滚动效果，不能实现滚动内容中的字进行不同颜色的更改，下面实现一个无缝衔接的滚动动画，可以根据自己的需要进行艺术化的更改需要滚动的内容，也可以自定义更改滚动速度。

<template>
  <view class="container">
    <!-- 文字滚动条 -->
    <view 
      v-for="(item, index) in scrollItems" 
      :key="'text-' + index"
      class="scroll" 
      :style="{'--t': item.duration + 's'}"
    >
      <view class="scroll-row">
        <text 
          v-for="(skill, i) in skills" 
          :key="i"
          class="skill-tag"
          @click="handleSkillClick(skill)"
        >{{ skill }}</text>
      </view>
      <view class="scroll-row">
        <text 
          v-for="(skill, i) in skills" 
          :key="i + 'copy'"
          class="skill-tag"
          @click="handleSkillClick(skill)"
        >{{ skill }}</text>
      </view>
    </view>

    <!-- 彩色方块滚动条 -->
    <view class="scroll img-box" style="--t: 25s">
      <view class="scroll-row">
        <view 
          v-for="n in 9" 
          :key="n"
          class="color-box" 
          :style="{'--r': (n-1)*40}"
          @click="changeBoxColor(n)"
        >{{ n }}</view>
      </view>
      <view class="scroll-row">
        <view
