Bootstrap 4.5 代码未按预期工作

我是 Bootstrap 的初学者，我正在关注 bootstrap 文档。尽管如此，我的代码仍然无法正常工作。我的文件夹只包含一个 index.html 文件。

Visual Studio 代码截图。

<!doctype HTML>

<html>


<head>

<!-- Required meta tags -->

<meta charset="utf-8">

<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">


<!-- Bootstrap CSS -->

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.0/css/bootstrap.min.css"

    integrity="sha384-9aIt2nRe3js3W69CrMinNGtLdWyYrnnKzHR26vu4tDT5MYYxFfc+NcPb1dKGj7Sk" crossorigin="anonymous">


<title>WeGo</title>

</head>


<body>

<div class="container">

<!-- This part is not working. The bootstrap styling or classes are not working -->

    <nav class="navbar navbar-expand-lg navbar-dark bg-primary">

        <a class="navbar-brand" href="#">WeGo</a>

    </nav>

</div>


<!-- Optional JavaScript -->
