1.自定义导航器位置

可以在swiper容器外，再套一个div盒子，然后给外面的盒子加上相对定位。这样在移动到导航按钮位置，相对的是外面div的位置，而不是swiper容器的，就不会被swiper容器遮挡住了。

2.自定义滚动过度效果

给.swiper-wrapper加上过渡属性，并且加上!important，因为原本的过渡效果是行内样式添加，如果直接设置优先级不够，不会生效。

备注：在设置css样式时，给swiper容器加上:deep深度作用，这样swiper里面的样式就自由支配了。

<script setup lang="ts">
import { reactive,ref } from "vue";
import { Navigation } from 'swiper';
import { Swiper, SwiperSlide } from 'swiper/vue';
import 'swiper/css';
import 'swiper/css/navigation';
const modules = [Navigation]
</script>

<template>
    <div class="container">
      <swiper 
        :modules="modules" 
        :slides-per-view="5" 
        :slides-per-group="5" 
        :space-between="10" 
        navigation>
        <swiper-slide>Slide 1</swiper-slide>
        <swiper-slide>Slide 2</swiper-slide>
        <swiper-slide>Slide 3</swiper-slide>
        <swiper-slide>Slide 4</swiper-slide>
        <swiper-slide>Slide 5</swiper-slide>
        <swiper-slide>Slide 6</swiper-slide>  
        <swiper-slide>Slide 6</swiper-slide>
        <swiper-slide>Slide 6</swiper-slide>
        <swiper-slide>Slide 6</swiper-slide>
        <swiper-slide>Slide 6</swiper-slide>
      </swiper>
    </div>
</template>

.container{
    position: relative;
  }
  :deep(.swiper) {
    position: initial;
    .swiper-wrapper{
      transition: all 1s !important;
    }
    .swiper-slide {
      width: 240px;
      height: 305px;
      background-color: #27bb9a;
    }
    .swiper-button-prev {
      left: 1190px;
    }
    .swiper-button-next {
      left: 1220px;
    }
    .swiper-button-prev,
    .swiper-button-next {
      width: 20px;
      height: 20px;
      background-color: #27ba9b;
      top: 80px;
      &::after {
        font-size: 12px;
        color: white;
      }
    }
    .swiper-button-disabled{
      background-color:#ccc;
      cursor:not-allowed;
      pointer-events:initial;
    }
  }
