Huddle page using flex, grid and discovered icons library fontawesome

This my 3rd challenge,ge on frontendmentor.io and i faced difficulties to choose technologies. After trying floating boxes to display the main part in 2 columns, i finally use grid for the 2 columns, flex for the rest of the page and float for the medias icons. I also experiment a layout in my css stylesheet. I don't know if there is a good practice about that but i started by the typography then the layout. Any feedback about this page will be very appreciated.
