By means of a shortcode, certain functionalities (for example, a contact form) are positioned on a page at the location of the shortcode in WordPress. The shortcodes are realized with square brackets [ shortcode ].
Depending on the functionality, values can also be transmitted to the shortcode. For example, as parameter "id" with the value "5": [ shortcode id=5]
Shortcodes are very popular in the development of a website with WordPress, but are becoming increasingly irrelevant in the wake of the new Gutenberg editor. This is because the Gutenberg editor allows you to visually render the website, similar to what is possible with a PageBuilder.
