Is it possible to give rights to edit information without full access to the site?

Question

Copywriting

Expanded: site on Bitrix, I want to transfer the site to the copywriter for content with full access to editing information (creating and deleting pages, adding content), but I do not trust so much to transfer full access to the code (to exclude the possibility of stealing an expensive template).
PS The site is not big and is under development, I would not want to bother with Git.

Answer 1

Not familiar with Bitrix.
But for any CMS, the following solution should be available:
1) Creation of a content manager role for a certain type of CMS content (the role carries the necessary restrictions on CMS objects and the FTP directory);
2) Creating a content manager user account and assigning it to a role;

Answer 2

If the site is made on infoblocks, then there are no problems.
There is a special content editor user...
He does not have access to the code.

Answer 3

depending on what and where, in general, yes, but no one does this, because there are too many places where you can edit on the site, this is aggravated by a poorly developed "media library", in fact, no one uses it, as a result, files are placed via FTP (there is also the possibility of a drag drop but few people use it)
It is also required to edit index files, and here and full access is not far away, everything depends on the need
