Responsive Component Sign Up with Validation

Hello! Great job, the responsiveness looks good too~

I have a few suggestions:

1. You could set the padding for left & right too on your form element then set width:100% on the input elements inside. If the input element overflow the form, set its box-sizing:border-box. 🤔

2. Don't miss out the label element for each input. 😀 But an alternative to it would be using aria-label attribute on the input element, since the label isn't gonna be displayed anyway.

Good challenge Darwin, it would be nice if you could add some feedback when the form was submitted correctly, nothing else to add, good job.
