TL;DR: Not Possible.
The codes which you are referring here are completely front-end. They are limited to how website look and function. I am stating here clearly so you can understand.
HTML: Makes the skeleton of Webpage. In simpler works its like just a frame of Door made with chunks of wood.
CSS: This gives color and looks to the webpage. Just continuing from previous example, it is like giving coating of color and finishing to outside of door.
JavaScript: Now, this is little advanced and it gives behavior to the website. Just like that door example, it gives functioning to the door how it opens and closes by either rotating the knob or simply pushing though.
These all come under Front end.
Now for the database of website like managing how many users are there or how many can use or come inside that door are managed through back-end programming for that you need to first learn about SQL ( Structured query Language) or RDMBS (Relational Database Management System) and then move further to Node.js (if you want to take javascript as main). Then only you can think of making a shopping website or even a social networking website like facebook.
