CSS Phone Illustration with some JS functionality

Hello everyone, any feedback is much appreciated. Not sure if I made the phone to small or should increase size for a higher resolution device.

As I was building the phone styling I decided to use a real textbox and button. Then thought they were pretty useless since it's just an illustration 🤔......💡 unless it actually submits a message.

It has no practical use but was fun so what the hell.

Note: custom scrollbar styling in phone illustration can be seen in Chrome. Other browsers may vary
