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

the things I'm most proud of:

• readable clean code
• the time took me to do this project
• a good validation code (with the help of kiara523)

things I'd do differently next time:

• use a framework for validation
• use a different approach to toggle elements

What specific areas of your project would you like help with?

i've put the element in the center but its not like that in the screenshots, how should i fix it

• how to toggle elements using

element.style.display='none';
element.style.display='flex';

• how to choose an img that wouldn't have problem when published in github pages
