The theme is mobile ready and responsive by default, so logically speaking you shouldn’t be needing any further changes.
Solution for this topic
Ok I figured out what’s wrong and its quite stupid (on WordPress side not Jevelin’s). The page was set as the default “Posts Page” under Settings -> Reading, which ignores any templates and uses index.php instead.
It would be good if you could add a feature to overwrite this (other themes do).
Unfortunately it doesn’t make any difference. It works correctly on all other pages but not on the Blog category listing.
Thanks for your reply. The template selection dropdown is not showing. Keep in mind I am using Jevelin-Child theme. I have already copied page.php and page-blog.php in the child-theme dir.
I even edited the postmeta in the database and pointed _wp_page_template to the right file but didn’t make any difference. Does Jevelin have any built-in cache?
