HI,
It is possible by custom JS codes, follow the guide:
1. install a plugin to add the JS codes:https://doc.seatheme.net/general-topics/how-to-custom-a-wordpress-theme/#javascript-codes
2. find the post unique ID follow: https://doc.seatheme.net/wordpress-faqs/custom/wordpress-post-page-id/
3. add the custom JS codes:
jQuery(document).ready(function( $ ){
$('.postid-1,.postid-10').addClass('page_from_top')
});
1 and 10 is the ID of the posts.
If you want to set it for only one post, use the JS like:
jQuery(document).ready(function( $ ){
$('.postid-1').addClass('page_from_top')
});
