Responsive landing component using CSS grid layout

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

I am proud of to use all grid and flex-box. I uploaded grid layout version as name of the project expect it, but I also add style-flexbox.css for the sake of practice.

I like concept of using flexbox for inner subelements, applying padding or other attributes to adjust size of the element, then using grid layout to structure and control of the outer frame.
