        <p>The HTML5 video element uses an mp4 video as a source. Change the source video to add in your own background! The header text is vertically centered using flex utilities that are build into Bootstrap 4.</p>
        <p>The overlay color can be changed by changing the <code>background-color</code> of the <code>.overlay</code> class in the CSS.</p>
        <p>Set the mobile fallback image in the CSS by changing the background image of the header element within the media query at the bottom of the CSS snippet.</p>
