How is the site organized and how to manage it?

Question

CMS

Hello!
Could you please explain how the site works / how to manage the content?
Let's say I have files: html, css, js.
Editing information in the news section in html every day is somehow not right and at least inconvenient.
In this situation, you need to "pull" html, css on the CMS? And how many sites use CMS for management?
Do I need to know a server-side language in order to write a managed site?
Please explain globally - how does the site work / how to manage content?
Thank you.

You need to "stretch".
Almost everyone uses a CMS to manage their website.
By managed site, do you mean: "write your own CMS, so as not to use a ready-made solution"? If so, then you need to be a virtuoso of backend development, here you simply won’t get off with knowledge of the language.
Learn CMS and you will no longer have the question of how to manage the content of the site. Above wrote the most popular CMS.
