I have always wanted to make a WORKING login/signup page.

okay to make a working signup page is not a easy feat. first you you really cant do it without knowing a backend language like nodejs, php or python. I reccomend nodejs.

heres a working project with login and signup. Youre also gonna need a database to store your users.
heres a framework that might help:

Learn nodejs. after maybe a year of hard work you can learn express and mongodb to make a basic login and signup.

or you could use firebase
