Responsive landing page using Flex Box

Wow.....That took longer than expected. 😨

When I started this challenge, I want to use as little Media queries as possible, with using grid's auto-fill/auto-fit properties. I struggled, so much with that. So I scrapped grid and used flex box instead.......and media queries.

I am interested how anyone would go about using as little media queries as possible, and with grid?

Any feedback is welcome - My personal criticisms are that I would like to be more efficient with media queries, and code.....conciseness?

Thank you in advance! 😁
