嘿,我正在为我的网页做旋转木马引导,但我有一个问题,用户上传的图像大小。当用户上传一个更大的图像大小,它会显示在我的网页。如何使图像大小跟随旋转木马的大小,这是我的旋转木马宽度是100%的查看屏幕?即使图像的大小是正方形,它会扩大图像在旋转木马。
这是我的网页布局。

在我尝试了1的答案,这是添加css。

img.d-block{
    width: 100%;
    height: 100%;
    object-fit: cover;
    object-position: center;
    }

"变成这样"

这是我的 Bootstrap 5.css

.carousel {
    position: relative
}

.carousel.pointer-event {
    touch-action: pan-y
}

.carousel-inner {
    position: relative;
    width: 100%;
    height: 500px !important;
    overflow: hidden
}

.carousel-inner::after {
    display: block;
    clear: both;
    content: ""
}

.carousel-item {
    position: relative;
    display: none;
    float: left;
    width: 100%;
    margin-right: -100%;

@media (prefers-reduced-motion:reduce) {

.carousel-item-next,
.carousel-item-prev,
.carousel-item.active {

.carousel-dark .carousel-indicators [data-bs-target] {

.carousel-dark .carousel-caption {

这就是我的index.blade.php

    <div class="carousel-inner">

我将height:100%添加到.carousel-item。并将这些样式添加到图像:

img.d-block{
  width: 100%;
  height: 100%;
  object-fit: contain;
  object-position: center;
}
