Mobile first CSS Grid (Page) combine with Flex Box (Component)

Hello everyone,

When I first experienced with css grid, I said to myself Oh this is easy.

Here I'm trying to solve issues using it combined with flex box. It was not easy but I made it.

It was a pleasure for me to complete this challenge I learn a lot.

As you probably understood, I in this challenge I tried to see if I could apply CSS grid mixed with flexbox.

Please let me know if I did something wrong combining these two wonderfull technologies.

Also, is my use of max-with as I did for text and title is something considered as best practice

Thank you all
