javascript - css-如何向图像添加动态 slider ？

Question

我创建了一个动态布局，它从我的 banner 表中检索图片并显示在 View 页面上。我已经在我的 laravel 元素上设置了模型和 Controller 。它看起来像下面这样:

它检索 2 张图片，但将其堆叠在另一张下面。我想知道是否有一种方法可以将其设置为 slider ，即第一张图片将向左/向右滑动并自动更改为第二张图片，依此类推。

我的代码:

<!-- Banner Area Start -->
  <section class="hero-area">

        <div class="hero-area-slider">

          <!--class for display banner -->
          <div class="intro-carousel">
            @foreach($data as $pic)
              <div class="intro-content" style="background-image: url({{asset('/images/'.$pic->photo)}})">
                <div class="container">
                  <div class="row">
                    <div class="col-lg-12">
                      <div class="slider-content">
                      </div>
                    </div>
                  </div>
              </div>

          </div>
              @endforeach
        </div>     
  </section>
  <br>

          -webkit-transform: scale(1.2);
          -ms-transform: scale(1.2);
          transform: scale(1.2); }

我想知道是否可以添加 slider ，我也可以使用鼠标并向左或向右单击/拖动，以便更改图片。谢谢
