Your website is a combination of pages, content and widgets. In order to build your site, you will first create pages. This is the foundation of your site and creates your site structure.
Once your site structure is complete, it's time to focus on your content. You should plan your content before you start placing it in your site.
When your content is ready, you will display it on your pages using widgets. You will be able to choose from a list of widgets that are designed to display different types of content.
As you are building your site, keep accessibility in mind so site visitors with disabilities can access your content.
