Does anybody build a website from scratch?

Hello,
I am new to web creation and have a doubt. After learning HTML CSS Js PHM SQL Responsive design and a bunch of stuff, I realise that it seems that nobody uses it. It feels like everything is based on templates, copy-paste, frameworks... It's not that I don't like it, I just feel lost.

What should I learn next to be up to date in web creation? I need front and back functionalitlies.

Thanks a lot
