The purpose of creating pages is different from creating posts, where pages are containing more information with refined layout, such as grids and responsiveness, we usually edit pages with Elementor for hybrid contents with more control of styling.
A new page contains nothing unless you add elements inside it. There are two types of page construction:

- A page built with Elementor components (layout and contents)
- A page built with simple editor for images and texts, etc.

When you navigate to the pages in admin dashboard, the page will be running into the mode of editing with Elementor, you may refer to the method of editing contents with it.
