Shortcodes are a very powerful feature of WordPress. In essence a shortcode is a placeholder for some other content. A well-known shortcode is the built-in gallery shortcode. Just type into the WordPress editor and it will be replaced by a gallery of images taken from media uploaded to the post.
If you need to do any repetitive tasks in the post editor or you need a specific HTML format which takes a while to mark up, you may find that your own shortcode can help.
In this article I’ll show you how shortcodes work and how you can create your own through some easy examples.
