Multi Step Form Site (HTML/CSS/Vanilla JS)

Hi all,

This is one of the must fun challenges on Frontend Mentor I've encountered so far. It's a really great exercise for someone who wants to get into HTML forms and form submission on the page. Having said that, I would like to hear your opinion on few stuff:

• Does form handling look OK to you?
• How do you like responsiveness of the page?
• Is there a way I can refactor CSS code to be more intuitive and readable?
• Based on this solution, what would be the best topics for me to learn more and improve?
