Responsive landing page using flexbox

Hi🙋🏻‍♀️ So I've completed this challenge and it was like: oh this is the biggest code I've written till now😅 Actually, I wanted to try starting with the small screens design then putting the large screens one in media query... and this was soooo hard😪 It took me 4 days to complete the challenge like this was so weird for me 'cause I'mused to complete challenges in 2 days maximum🤦🏻‍♀️

For me honestly, It's a bad idea starting with mobile screens🙅🏻‍♀️ AVOOOID IT...

At the end, I want to say that any feedback is welcome😊
