Responsive landing page using CSS Flexbox

What are you most proud of, and what would you do differently next time?

The best points of this project is:

1. getting to use CSS flexbox
2. learning how to do a README.md

But i would like to do a cleaner code next time

What challenges did you encounter, and how did you overcome them?

The most difficulty part was learning the difference between the flex-containers and the flex-items

What specific areas of your project would you like help with?

Would like any feedback about getting a code more clean or tags that i could use instead of other for better efficiency
