Basic HTML/CSS, flexbox and grid layouts

Hi guys !

Already my second challenge here, but this time coding on an old laptop having a really low resolution that didn't help me adjust all box and text sizes perfectly... However still learned a lot of things that I sometime added as comments to follow my learning.

Again, if you have any recommendation regarding my code organisation or whatever, please don't hesitate to share your thoughts with me as this will help me a lot !

Have a nice day ;)
