Set up the basic HTML structure with Bootstrap CDN

Create a basic HTML5 page with lang="en", meta charset="UTF-8", and viewport meta tags. Include Bootstrap 5 CSS and JS CDN links inside the <head> and before the closing </body> tag respectively. Add a <main> section with a container <div> inside the <body>.

Add a button with popover attributes

Inside the <div class="container">, add a <button> with type="button", Bootstrap classes btn btn-primary, and these attributes: data-bs-toggle="popover", title="Popover Title", data-bs-content="This is the popover content.", and aria-describedby="popover1". Give the button an id="popoverButton".

Use the data-bs-toggle="popover" attribute to enable the popover on the button. Add a clear title and content for the popover.

Initialize the popover with JavaScript and set triggers

Add a <script> block before the closing </body> tag. Inside it, write JavaScript to select the button with id="popoverButton" and create a new Bootstrap Popover instance on it. Set the popover triggers to hover and focus using the trigger option.

Use new bootstrap.Popover(element, { trigger: 'hover focus' }) to enable the popover on hover and focus.

Add aria-label and finalize accessibility

Add an aria-label="More info about the button" attribute to the <button> element to improve accessibility. Ensure the button has a clear label for screen readers.
