Base Apparel coming soon using CSS and JS Constraint Validation API

This marks my 10th and last "Newbie" challenge in frontendmentor, it's been a little over one month when I set a goal to complete them and now I'm happy that I finally did! I learned a lot already and I'm very excited to learn even more when I start with "Junior" challenges. Feel free to review and give me any feedback you may have. Thanks!
