Responsive landing page using vanilla CSS

This project was great practice for creating a responsive layout using Grid and Flexbox. I ended up with a 500+ line CSS file, so next project I'd like to use SCSS to organize my styles better. I'm still building my knowledge of accessibility and semantic HTML, so if there's anywhere I can improve in those areas, I'd love to hear it. For this challenge I used the <article> tag for the first time and a few ARIA attributes.

Would love to hear your feedback, and if you'd like to share your solution that would be great. 🙂
