Bootstrap3图像在标题下，重新缩放图像以适合

Question

我正在使用HTML和JS创建一个简单的轮播。我主要拥有现在想要的外观，不幸的是存在一些问题：

运行代码段：

1）我希望标题位于图像下方的空间中，而不是图像上方。我已经根据自己的小技巧完成了CSS可以做的事情，无法弄清楚。

2）另外，我希望调整图片的大小和居中，以使其适合转盘，而不是裁剪大部分。

旋转木马突出

1）我已经使网站响应，并且容器具有style="text-align:center;text-align: justify;"。但是，如果您看下面的图片，则在某些情况下最小化浏览器窗口时，轮播会突出。我该如何解决？

.carousel-caption {
  position: relative;
  left: auto;
  top: auto;
  bottom: -95px;
}

.carousel-inner {
  overflow: visible;
  padding-bottom: 95px;
}

#serviceSlider .item {
  height: 400px;
}

#slide1{
  background:url('https://cdn.pixabay.com/photo/2020/03/31/19/20/dog-4988985_960_720.jpg'); center no-repeat;
}

#slide2{
  background:url('https://cdn.pixabay.com/photo/2017/02/20/18/03/cat-2083492_960_720.jpg'); center no-repeat;
}

#slide3{
  background:url('https://cdn.pixabay.com/photo/2018/05/09/22/44/piglet-3386356_960_720.jpg'); center no-repeat;
}

您不必做太多事情，只需对字幕轮播类进行一些更改。尝试复制和粘贴以查看是否可行。 CSS中没有其他更改。

<div id="carouselExampleCaptions" class="carousel slide" data-ride="carousel">
    <div class="carousel-inner">
        <div class="carousel-item active">
            <img src="https://cdn.pixabay.com/photo/2020/03/31/19/20/dog-4988985_960_720.jpg" class="d-block w-100" alt="...">
            <div class="text-center d-none d-md-block">
                <h5>First slide label</h5>
                <p>Nulla vitae elit libero, a pharetra augue mollis interdum.</p>
            </div>
        </div>
        <div class="carousel-item">
            <img src="https://cdn.pixabay.com/photo/2020/03/31/19/20/dog-4988985_960_720.jpg" class="d-block w-100" alt="...">
            <div class="text-center d-none d-md-block">
                <h5>Second slide label</h5>
                <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
            </div>
        </div>
        <div class="carousel-item">

            <div class="text-center d-none d-md-block">
