Interactive details form with Sass

Hello everyone! This challenge was challenging for me, but I learned a lot. -First, I learned about regex in javascript and how you can use them to evaluate the data the user types into the input fields. -Then, I learned about the input pattern attribute and, with the help of .checkValidity(), prevent the form from submitting if the input doesn't fulfill the conditions. -Learned a little bit more about positioning elements with CSS

I would appreciate it if someone would take the time to look at my code and give me feedback on how I could improve it!

Happy coding everyone
