How to find the id or the block itself in Bitrix?

Question

1C-Bitrix

Hello.

There is a site on the Bitrix engine, one block needs to be replaced. I've looked through all the files and can't find it.

Website - https://welcome-rent.ru/info/.
This page has a booking form - how to find this block with this form?

php code:
<?
require($_SERVER["DOCUMENT_ROOT"] . "/bitrix/header.php");
$APPLICATION->SetPageProperty("title", "Information for clients \"Welcome. Apartments for rent\"");
$APPLICATION->SetPageProperty("description", "The main activity of our company is the daily and hourly rental of apartments. All apartments of our room stock are located in the city center,
$APPLICATION->SetTitle("Customer information");
?>
Information for the company's clients 


We have collected information in this section that may be useful when choosing services.
<? require($_SERVER["DOCUMENT_ROOT"] . "/bitrix/footer.php"); ?>

As I understand it, the code is set inside the body, but it is not in the php code. How to find where it connects?

Answer 1

Your form is in an iframe. This is most likely a third-party booking widget, look for its connection in the header.php of your current website template
