how do i create login page for user and sellers using html/css/js

Question

login/signup for users and sellers

Answer 1

that's not enough
you need a database that store the usernames and passwords with a server side language to elaborate the result of query

Answer 2

no just i want to create front end

Answer 3

I guess, theoretically, you could design the front end. but without a backend, you'd have no means of testing it out?

So you wouldn't know if it worked or not.

I guess at a push, you could create arrays for users and passwords, and use that, but it's hardly a secure choice :/
