pod-request-access-landing-page with CSS positioning and JS

Hi everyone 👋🏽, Am very glad to have completed my second JS project but I faced a hard time implementing the UI design and the approach I took for using Positioning made it tricky to make my solution very responsive and I have noticed icons are not rendered well in Firefox on small mobile media queries so I humbly request for ideas on how to improve my solution and any feedback on my solution more especially highlighting weak areas in my code will greatly be appreciated.
