Responsive Chat app CSS illustration with HTML and CSS

What are you most proud of, and what would you do differently next time?

I am pleased to solve this challenge and leveled up to solve intermediate challenges, as I dive into Front-end Mentor, I solve many Challenges and strengthen my CSS foundation

In my opinion, the challenge is not so difficult, the main problem is that you will need a lot of time to make your solution look like the design

What challenges did you encounter, and how did you overcome them?

The two rectangles in the background presented a challenge to me. I gave them a lot of thought as to how to complete them and make them responsive to me, but I overcame the challenge and connected these rectangles to the two major sections, and they are also responsive.

I will take care of this tiny problem later. There is a second rectangle in the mobile vision that extends beyond the layout. If you have any suggestions, please share them with me.
