How to set id for hmtl tag in 1C-Bitrix?

Question

1C-Bitrix

To connect the jQUERY UI plugin to the template on Bitrix, you need to register css id.
I connected the library and registered the path to it in the template.
I found the necessary html tag through Firebug, but I can’t find where it is registered.
I looked through editing the page - 0.
Through editing the template, nothing either.

Open through editing the page. No HTML tag? Fine.
Looks at what components are connected on the page. They start with the
$APPLICATION->IncludeComponent() method;

See the first parameter. This is the name of the component. For example Bitrix.news.list
If this is a non-standard template, then it is usually located along the path /bitrix/tempates/mySiteTemplateName/components/bitrix/news.list/template/.default/template.php
If it is a standard one, then
/bitrix/components/bitrix /news.list/
Open it, edit it.
If you did not find the required component template on the page, then see the header or footer template.
/bitrix/tempates/mySiteTemplateName/header.php or footer.php
I advise you to read about the Bitrix namespace
