Chat illustration app using only CSS

First non-newbie Challenge! I decided to level up my designs a little and challenged myself with an intermediate challenge to see if I could solve it. And boy did I meet difficulties 🙂

The hardest thing for me was to make the "background" shapes responsive, although it isn't perfectly responsive, I think it's good enough. I'm sure there was a cleaner way of doing it but I just couldn't think of any other way to do it.
