::-webkit-scrollbar 滚动条整体部分，可以设置宽度等
::-webkit-scrollbar-thumb 滚动条里面的滑块
::-webkit-scrollbar-button 滚动条轨道两端的按钮，允许通过点击以微调滑块的位置
::-webkit-scrollbar-track 滚动条的轨道(里面装有thumb)
::-webkit-scrollbar-track-piece 滚动条没有滑块的轨道部分
::-webkit-scrollbar-corner 当同时有垂直滚动条和水平滚动条时的交汇处
::-webkit-resizer 某些元素的corner部分(如textarea的可拖动按钮)

对此有了一些了解之后就可以上手滚动条样式的修改了。

代码实现：

<ul class="nav-tabs-scroll">
  <li v-for="(item,index) in tabs" :key="index" class="nav-item-scroll">{
<!-- -->{item.text}}</li>
</ul>
<v-textarea outlined v-model="text" style="width: 200px; margin: 16px;" class="text"></v-textarea>

data: () => ({
      tabs: [
        { value: 4001, text: 'Loan Log', code: 'LOAN_LOG' },
        { value: 4002, text: 'Document Log', code: 'DOCUMENT_LOG' },
        { value: 4003, text: 'Note Log', code: 'NOTE_LOG' },
        { value: 4004, text: 'Operation Log', code: 'OPERATION_LOG' },
        { value: 4005, text: 'Payment Log', code: 'PAYMENT_LOG' },
        { value: 4006, text: 'Maintenance Log', code: 'MAINTENANCE_LOG' },
        { value: 4007, text: 'Transaction Log', code: 'TRANSACTION_LOG' },
        { value: 4008, text: 'Collection Log', code: 'COLLECTION_LOG' },
        { value: 4001, text: 'Loan Log', code: 'LOAN_LOG' },
        { value: 4002, text: 'Document Log', code: 'DOCUMENT_LOG' },
        { value: 4003, text: 'Note Log', code: 'NOTE_LOG' },
        { value: 4004, text: 'Operation Log', code: 'OPERATION_LOG' },
        { value: 4005, text: 'Payment Log', code: 'PAYMENT_LOG' },
        { value: 4006, text: 'Maintenance Log', code: 'MAINTENANCE_LOG' },
        { value: 4007, text: 'Transaction Log', code: 'TRANSACTION_LOG' },
        { value: 4008, text: 'Collection Log', code: 'COLLECTION_LOG' },
        { value: 4001, text: 'Loan Log', code: 'LOAN_LOG' },
        { value: 4002, text: 'Document Log', code: 'DOCUMENT_LOG' },
        { value: 4003, text: 'Note Log', code: 'NOTE_LOG' },
        { value: 4004, text: 'Operation Log', code: 'OPERATION_LOG' },
        { value: 4005, text: 'Payment Log', code: 'PAYMENT_LOG' },
        { value: 4006, text: 'Maintenance Log', code: 'MAINTENANCE_LOG' },
        { value: 4007, text: 'Transaction Log', code: 'TRANSACTION_LOG' },
        { value: 4008, text: 'Collection Log', code: 'COLLECTION_LOG' }
      ],
      text: ''
    }),

<style lang="scss" scoped>
