Bootstrap 5 Hello World

Getting started with Bootstrap 5 is a actually a lot easier than it seems from reading the Bootstrap 5 Getting Started documentation. If you are content with the default fonts, colors, sizes, and so forth, then the fastest way to get going is to use a CDN to load the Bootstrap 5 CSS and Javascript files. Let’s see how to create a web page formatted using Bootstrap 5 in IntelliJ in five quick steps:

1. Create a Web project

First, create an empty project in IntelliJ. Let’s call it “BootstrapWorld”:

2. Create index.html

The HTML is

<div class="container">
  <h1>Bootstrap 5 Hello World</h1>
  <p>Welcome to a sample page formatted using Bootstrap 5.</p>
</div>

To verify that this font is this, bring up Chrome Developer tools and scroll to the bottom of the “Computed” tab. The rendered font(s) are listed:
