<article>
    <hgroup>
        <h1>Hello, world!</h1>
        <p>This is a simple hero unit, a simple jumbotron-style component for calling extra attention to
            featured content or information.</p>
    </hgroup>
    <hr>
    <p>It uses utility classes for typography and spacing to space content out within the larger container.
