Sometimes you may want a different look and feel for certain posts on your website. For instance, you may want to use a different layout for featured articles or stories in a particular category.

This is where you’ll need a custom single post template in WordPress.

By default, WordPress uses the single post template based on WordPress template hierarchy. All themes come with a single.php template which is used as the default for all your single posts.

Some themes may also include additional templates or layout choices that you can use.

It is very much like creating a custom page template. Most WordPress themes also come with page templates that you can use while editing a page in WordPress.
