左右にスライドするナビゲーションバーをHTMLに実装する方法

<div class="swiper-container">
  <div class="swiper-wrapper">
    <div class="swiper-slide">slider1</div>
    <div class="swiper-slide">slider2</div>
    <div class="swiper-slide">slider3</div>
    <div class="swiper-slide">slider3</div>
    <div class="swiper-slide">slider3</div>
    <div class="swiper-slide">slider3</div>
    <div class="swiper-slide">slider3</div>
  </div>
</div>

初始化
<script>
var mySwiper = new Swiper(&#39;.swiper-container&#39;, {
    autoplay: true,//可选选项，自动滑动
    freeMode:true,//滑动不够一格，不会自动贴合
    slidesPerView:4,//设置slider容器能够同时显示的slides数量
})
</script>
