How do I change the style of an automatically generated post page?

The style of the post page, including background colour, date location, images, recommendation buttons, ‘See also’ section, and link to the post will be sourced from the FD*** block that contains the post. If a post is published on several pages in different FD*** blocks, its style settings will depend on which page the post category is assigned to.

You can change linking of a category to a page in the Feed settings → Categories → click on the Feed category → Additional settings → Select the Category Posts Page → Save the changes. Once you have completed this, you need to go to any post card and click the ‘Save’ button.
