  Challenge: Adjust the layout for wider screens
    - Add a media query that targets a browser width of 576px or wider
    - Within the media query, convert the parent element of .intro and 
      .main-content to a flex container
    - Set the width .intro and .main-content to exactly
      half the total width of their parent container
