PHP files to modify to configure blog and categories

Hi @ziordia68,

Thanks for using our theme. For the category pages and blog page styling, you could target the body class added on the page https://prntscr.com/qq10hc to add the custom CSS on the pages.

Please let me know if this fix the issue.

Yes, thank you! It was OK. But I am trying now to make new templates in a child theme. Thanks a lot!
