CS50Web - Project 3 Mail Design

This is a design I made for a CS50Web Programming project.

It's a single page web-app that allows registered users to send emails to other registered users on the platform.

Overall, I think I could've done a better job but since my time was limited, and the project didn't require a design, I'm okay with that I achieved.

I want to improve my design skills so any kind of feedback is appreciated !

Thank you!
