Layout

Yes, I read the doc on the official website and watched the video, but I don’t understand how to do it right, and there are no such examples on the Internet that I need, can someone explain how this can be implemented?
Here is what I have so far:
Field groups:

Pages:

Here is the value of the main page:

And here is the Services page:

Answer 1

In the_field and get_field specify the page ID as the second parameter. For example, if the field values ​​are specified for the main page, then the ID of the main page.

$value = get_field( "text_field", ID_страницы );

<?php the_field( 'text_field', ID_страницы ); ?>

Answer 2

Hello!
Given that the footer, header and sidebar are "common" areas, it would be more logical to use acf_option.
Create a menu item "Theme Options" and display settings in the right places via the_field || get_field adding 'option'
And so, of course, you can just pass the ID of the page for which you chose to display custom fields. Those. if you load them on the main page, then pass the id of the main page to the custom fields and, accordingly, they will be available for other pages
