Responsive page with CSS Flexbox

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

I'm proud that I managed to pin the footer to the bottom of the page and the speed with which I completed the challenge.

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

I had some difficulty to pin the footer at the bottom of the page. So I searched on Internet how to do it and learned how to do it with Flexbox properties.

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

Any help is welcome!
