There are several WordPress plug-ins available online that can fulfill every need imaginable. But when you are using WordPress.com, then it is difficult to install plug-in because WordPress.com has its limitations. In order to use the plug-in, you need to have a self-hosted WordPress.org. To avoid such hassles, you can get your job done with the help of a simple snippet. It is generally the path of least resistance. In this article, we will discuss different useful snippets from around the web, all of which can make your experience with WordPress a little bit easier and more functional.

A snippet is a small piece of PHP code that can be used to enhance the functionality of a WordPress powered website. It can be considered as a mini-plug-in with fewer loads on your website. Snippets are an easy, clean and simple way to add code to your website.
