fixes for code quality issues. trailing whitespaces, whitespaces between text and tags, things inside of a div element should be indented and placed on their own line, line breaks (<br>) should be placed at the end of the preceding line, parts of your HTML file that have been deprecated are commented out instead of being removed entirely.
fixes for review. tabs and spaces are mixed.
remaining fixes for responsiveness. centered circle div elements. changed hero image max width to align better with header text. revised styles to accomodate mobile devices in the header view more smoothly. fixed header text centering in mobile devices. kept the style that removes logo display on small mobile views.
