Page made using flex and relative

Hi 👋

• You should remove background-color property from main and add it to body. Thus, you can fill the light gray color to the whole page.
• You should add margin: 5rem auto to body selector to ensure desired result.
• You should use grid or flexbox for smooth responsiveness instead of relative/absolute etc. (my suggestion is Grid, btw.)

Apart from these, it's looking good. Well done 👊
