Snippet is a simple, easy and small piece of PHP code that can be added on your site to extend the default functionality of your WordPress website.
In WordPress, a snippet is a small piece of code that can be added to the functions.php file or using a plugin to add specific functionality to a WordPress site. Snippet almost works as a mini plugin and requires no installation at all.
These code snippets are commonly used to customize the look and feel of a website, add new features and functions, or fix issues that may arise. Snippets can be found online or created by developers, and are often shared within the WordPress community as a way to improve the functionality and usability of WordPress sites.
