The Bootstrap CSS library is failing to load

Struggling with a tutorial on Bootstrap that walks me through adding a link from the website to my file, but for some reason, the code within the body tag (the div element) is not displaying as expected. Any thoughts on what might be causing this issue?

<!DOCTYPE html>
<html lang ="en">
    <head>
        <title>Hello!</title>
        <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.3/css/bootstrap.min.css" integrity="sha384-TX8t27EcRE3e/ihU7zmQxVncDAy5uIKz4rEkgIXeMed4M0jlfIDPvg6uqKI2xXr2" crossorigin="anonymous">
    </head>
    <body>
        Hello, world!
        <div class="alert alert-success" role="alert">

          </div>

Answer №1

Give this a try

<!DOCTYPE html>
<html lang ="en">
    <head>
        <title>Hello!</title>
     <!-- Bootstrap CSS -->
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
    </head>
    <body>
        Hello, world!
        <div class="alert alert-success" role="alert">
            A simple success alert—give it a shot!
          </div>
    </body>
</html>

Additionally, I strongly recommend utilizing the bootstrap-boilerplate for your project

   <head>
      <meta charset="utf-8">
      <meta http-equiv="X-UA-Compatible" content="IE=edge">
      <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
      <title>Bootstrap-boilerplate</title>
      <!-- Bootstrap CSS -->
      <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css">
   </head>


   <body>
<!-- Optional JavaScript-->
<!-- Start with JQuery, followed by Popper.js and finally Bootstrap JS-->
      <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
      <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script>
      <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js" integrity="sha384-h0AbiXch4ZDo7tp9hKZ4TsHbi047NrKGLO3SEJAg45jXxnGIfYzk4Si90RDIqNm1" crossorigin="anonymous"></script>
   </body>
