The other option is for you to create custom pages.
We recommend using simple pages when you don’t think the page structure will be reused later or for other pages, so it makes more sense to build one from scratch or even use one of your theme’s templates.
For example, for your About Us page, Contact Us page, or Homepage. These pages are standalone, so creating a new template that will only be used once doesn’t make sense.
To create template pages, you can code one from scratch, if you know PHP. Or you can use a page builder, such as Elementor or Beaver Builder.
Page builders usually provide a simple tool to create custom templates for your website that can be easily applied to post types, or pages in a certain category, tag, or any other parameters.
After you create your custom page template, you can make them apply to certain Post types, such as blog posts, authors’ pages, or your courses pages. Or they can be stored for later.
