I’ll build this as a full advanced content-single.php template for your RX Theme, including SEO-friendly article markup, author box, breadcrumbs hooks, sharing, related areas, post meta, schema-ready structure, pagination, comments, ads/hooks, and safe WordPress escaping.
Yes friend — this file can be very powerful. Below is an advanced RX Theme single post template for:
template-parts/content/content-single.php
It uses safe WordPress escaping, semantic <article> markup, featured image, categories, tags, author box, reading time fallback, share buttons, post pagination, previous/next navigation, comments, edit link, hooks for ads/plugins, and schema-friendly structure. WordPress supports dynamic template tags such as the_content(), wp_link_pages(), comments_template(), and author meta functions for templates. get_the_author_meta() returns author data for use in PHP, especially inside the Loop.
