Shortcode
A WordPress markup tag that embeds dynamic content or functionality in posts and pages using bracket syntax.
A Shortcode is a WordPress-specific markup tag that lets you embed dynamic content or functionality within posts and pages using a simple bracket syntax like [shortcode_name].
Usage
Shortcodes can accept attributes: . They can also wrap content: [highlight]Important text[/highlight].
Creating Shortcodes
Developers create shortcodes using add_shortcode() in PHP. The callback function processes the attributes and returns HTML output.
Gutenberg Alternative
While shortcodes remain fully supported, WordPress now recommends using Gutenberg blocks for new functionality, as they provide a visual editing experience.
