All solutions

During this project i started learning about patterns, pattern validation and regex, it was a fun project, i also struggled a bit with the layout of the page and the responsive look for mobile, but i think i manage to work it out and made it look good in general, the js script was not as hard but again i'm not sure if i overcomplicated myself and could have used a better approach to it, then again, the most important part is that it works. In general I'm satisfied with the results, any feed back is very welcome :)

I tried to do the javascript part with the little knowledge i have atm and i think it could've been more efficient and short, but it gets the job done so i'm ok with that and i learned a lot checking others solutions when i finished :) I would like to know, could there be performance issues of any kind with the way i made the Js code?

Was my inclusion of scss useful? or should i had use more of the sass tools like mixin, maps and variables? Was flexbox the correct option for this challenge?

Thanks everyone for their feedback
