Which file specifies the order of blocks on the Bitrix website?

Question

1C-Bitrix

There is a site on Bitrix.
You need to swap 2 blocks.
Please tell me where the structure of the site is described, that is, the sequence of blocks and components.
There are no necessary blocks in the header.php and footer.php files.

Answer 1

Look at the physical file first. You can find out its location by URL address.
If there is no such file, then the page is created dynamically. Then you need to look in the site settings for the Rules for processing addresses and find out which physical file is responsible for displaying this page.
Block code can be placed in the following locations:
- template files
- page
file - complex component
template file - simple component template
file - include area file.
There is no universal answer. You always need to look and study in detail the code of a particular site.
