Previewing a site allows you to see how your site currently looks before you publish your latest changes publicly.
In order to view a preview, simply click on the Preview Button on the top right corner anytime. This will open up a new page rendering a working version of your site and displaying it exactly as it will appear to users.
Note that the Preview link is private and only visible to you. Sharing this link with other people will not work. To share your site externally you must publish and share the publish link.
