您已经结合了几个问题，这应该足以让您朝着正确的方向前进。

要移除容器两侧的间隙，请添加 Bootstrap class px-0 以移除填充：

<div class="container-fluid px-0">

您可以添加样式属性来设置轮播的垂直高度。但是，当图像的 height:width 比例与轮播比例不同时，图像将被裁剪：

<div class="carousel-inner" style="height: 300px;">

您可以通过添加纯色背景来修复导航栏，例如 bg-light:

<nav class="navbar navbar-expand-lg navbar-light bg-light fixed-top py-3"

并且由于您使用的是固定导航栏，因此您还应该添加一个垫片 div 来向下推动旋转木马。如果没有间隔符，内容将被导航栏隐藏。

<div style="margin-top: 70px;"></div>

但是，如果您希望导航栏显示在图像上方，请添加以下样式而不是间隔符：

  <nav style="background-color: rgba(255,255,255,0.6);" class="navbar navbar-expand-lg navbar-light fixed-top py-3"

并且由于您使用的是 bootstrap.bundle.min.js，因此您可以从您的页面中删除此脚本（您不需要两者）：

<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.2.0-beta1/dist/js/bootstrap.min.js"

运行了解其工作原理的代码段。
