Pages are what allow you to create structure for your sites, where you can add unstructured content and customize the routes from which that content is displayed.
You can create widget or content pages. Widget pages are based in a modular scheme you can use to create a customizable website using HTML, JS, and CSS. You can drag and drop the widgets we offer or custom widgets created by your team.
Content pages are our solution to connect the Content module to Channels. Here you can create the index page and the structure for all your entries using HTML, JS, CSS, and Liquid.
You can find more information about Pages in our documentation.
