A single post template creates a default design for your site’s new posts. This helps you maintain a consistent look and feel. You can use one template for all your posts or use different templates for different types of posts. For instance, in a cooking site, you may want to use one type of post for appetizers and another for main courses.
Single post templates are site parts and can be found by navigating to Elementor>Theme Builder.
