Does an h1 heading (with a class attribute!) count as an h1 heading, or is it a system tag from a template?

Question

Search Engine Optimization

We are talking about this page - https://list-prutok-spb.ru/product-category/list/l...
Will the Cold Rolled Steel Sheet be considered the main heading or will it be the second h1 on the page?

Answer 1

Nobody forbids having two h1 if that

Answer 2

Yes, it will be considered a normal H1 tag. But from the point of view of SEO optimization, this is not worth doing. All styles must be placed in separate css.
Also, there is no guarantee that the search robot will not "stumble" in your styles when reading the page. But this is easily checked through the webmaster.
As they say in the comments, no one forbids you to use two H1 )) But again, from the point of view of seo, you can’t do this. Heading with H1 tag should be one per page
