How to make a site without borders and builders on Wordpress?

Question

Layout

Hello. Tell me how to pull the layout on WordPress in 2021 without using additional fields and builders. You just need to insert the code from the usual layout. I've always pasted it into Pages, but I've been told it's wrong. How then is it correct? I avoid Gutenberg and others.

Answer 1

There are only three options
1. In the test field of the page - I really don't like it when they do it.
2. Through builders and various page builders
3. With the help of additional fields
Why don't additional fields suit you?
