Responsive Fylo Landing Page W/ CSS Grid , Flex

In my previous pages , i didn't pay attention to check predefined dimensions of smatphones and tablets when working on responsiveness and that made the page look a bit hideous when trying to go below 700px width for example ..

Thanks to some helpful comments i understood my mistakes and took my time with this one and despite some minor issues i'm really happy with the outcome :D

I'm more than happy to hear your opinions and tips .. :D
