Hello,
It would be greatly appreciated if you could assess my work.

Hi @Alaa_Seada and welcome to the community 
I see you already experimented with Flexbox and Grid. That’s some advanced stuff and you did a great job applying it. 
The Grid where you essentially just use a single column is a bit overkill, but as an experiment it’s well done.
Have a nice day and keep up the great work. 
Michael
