Shortcodes make it easy for anyone to add custom features to WordPress posts and pages without coding, but users with web development skills can also design custom shortcodes for just about any purpose using code structures in PHP, the programming language for WordPress itself. These custom shortcodes are placed in the site’s “functions.php” file and can be inserted into WordPress posts, pages, and widgets as needed.
Shortcodes are a quick and easy way to add an array of code-based functions and features within your site’s posts, pages, widgets, and more. Along with themes and plugins, shortcodes make it easy to create a unique, fully customized WordPress site – even if you’ve never worked with code at all.
