A jumbotron was introduced in Bootstrap 3 as a big padded box for calling extra attention to some special content or information.
Jumbotrons are no longer supported in Bootstrap 5. However, you can use a <div> element and add special helper classes together with a color class to achieve the same effect.

<div class="mt-4 p-5 bg-primary text-white rounded">   <h1>Jumbotron Example</h1>  <p>Lorem ipsum...</p> </div>
