Chat App CSS Illustration | HTML CSS Sass

Hello Everyone! 👋

I finally finished the first intermediate challenge. 🎉

This challenge is really testing my CSS skill, especially when making it responsive. 😆

Now for the questions:

• I added aria-hidden="true" for the phone, since it's just an illustration. Also because of that, I didn't use any interactive elements such as button and input. But, what do you think about this?
• I am struggling with making the two background that is on the top left and bottom right corner have a fluid layout. I had tried using calc(), clamp(), but I wasn't able to find the calculation for it. Do you have any solutions for this?
• I'm not sure what kind of animation should I make, so any idea about it would be appreciated.

Of course, other comments or any issue that you may find, feel free to write it down.

Also if you want me to give my feedback on your solution, feel free to give me the link on the community feedback! I will be glad to help you too!

Thanks!
