Base Apparel coming soon page Using CSS (GRID/FLEX) and JavaScript

I admit that this challenge hides some difficulty in terms of displaying the elements of the page. So I wonder if there is no way to do better than what I did. I am waiting for your feedback and ideas for improvement 😁. As for the validation of the form and the update of the style in javascript, I liked it as an exercise.

Tell me what you think?

good code to everyone😉
