I’ll build this as a complete advanced template-parts/post/author-box.php file for your RX Theme, with safe escaping, schema, social links, avatar fallback, author stats, and hooks so you can extend it later.
Below is a very advanced, feature-rich template-parts/post/author-box.php file for your RX Theme.
Create this file:
rx-theme/template-parts/post/author-box.phpThen paste this full code:
<?php
