如何在 Bootstrap 4 轮播中堆叠多个图像

Question

我不知道如何使用 Bootstrap 4，以及如何在一张幻灯片中显示多个小图像 \xe2\x80\x93（如缩略图\xe2\x80\x93），而不是让图像填充轮播的宽度。我已经使用下面的代码尝试了一些操作，但仍然无法堆叠许多图像。

<div class="container">\n    <h2 class="text-center">- Carousel -</h2><br>\n\n    <div id="carouselExampleControls" class="carousel slide" data-ride="carousel">\n        <div class="carousel-inner">\n            <div class="carousel-item active">\n                <img src="http://via.placeholder.com/250x250" alt="First slide">\n            </div>\n            <div class="carousel-item">\n                <img src="http://via.placeholder.com/250x250" alt="Second slide">\n            </div>\n            <div class="carousel-item">\n                <img src="http://via.placeholder.com/250x250" alt="Third slide">\n            </div>\n            <div class="carousel-item">\n                <img src="http://via.placeholder.com/250x250" alt="Fourth slide">\n            </div>\n            <div class="carousel-item">\n                <img src="http://via.placeholder.com/250x250" alt="Fifth slide">\n            </div>\n            <div class="carousel-item">\n                <img src="http://via.placeholder.com/250x250" alt="Sixth slide">\n            </div>\n        </div>\n\n        <a class="carousel-control-prev" href="#carouselExampleControls" role="button" data-slide="prev">\n            <span class="carousel-control-prev-icon" aria-hidden="true"></span>\n            <span class="sr-only">Previous</span>\n        </a>\n        <a class="carousel-control-next" href="#carouselExampleControls" role="button" data-slide="next">\n            <span class="carousel-control-next-icon" aria-hidden="true"></span>\n            <span class="sr-only">Next</span>\n        </a>\n    </div>\n</div>\n

您也可以在轮播幻灯片中使用标准 Bootstrap Grid 系统类。因此，您可以使用下面示例中的标记来实现示例中看到的行为。
该示例在一张幻灯片中显示了五个图像，一旦轮播滑动到下一个项目，它将显示下一个包含五个图像的块。

<div id="gallery" class="carousel slide" data-ride="carousel">
    <div class="carousel-inner">
        <div class="carousel-item active">
            <div class="row">
                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/caa8f5/ffffff?text=Image+1" alt="Image 1"/>
                </div>

                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/9984d4/ffffff?text=Image+2" alt="Image 2"/>
                </div>

                <div class="col">
                    <img class="img-fluid" src="http://via.placeholder.com/800x450/592e83/ffffff?text=Image+3" alt="Image 3"/>
                </div>

                <div class="col">
