I want to create a website but am just a beginner.
So where is its place?
This is an interesting case. It's a nut-n-bolts type question about website development, and I can see some arguments for it being considered a programming question. However it's also a simple question with a very broad and open ended scope, so it's possible that even if it's on topic, it's not appropriate for the stackoverflow format.
I think you'd be better off going to chat.stackoverflow.com and asking a series of questions there.
I think this belongs on webmasters.stackexchange.com. I don't think it's too open ended and could be answered with a quick overview of static vs dynamic pages.
