WordPress template hierarchy

WordPress has a template hierarchy, which means it will automatically look up templates based on which page is requested.

Example: if you're requesting the configured front page, it will first look for a front-page.php file. If it's not there, it will fall back to templates lower in the hierarchy:

front-page.php -› template-<name>.php -› page-<slug>.php -› page-<id>.php -› page.php
