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

I'm happy I was able to finish this simple project in a short time. I'm proud that, as a beginner, I looked up for solutions and learned a lot by myself.

It was difficult for me centralize the box in way that become responsive in desktop and mobile devices.

Also, I didnt know how to apply a shadow in div tag.
