A page layout template, also known as a layout template, holds the structure of the entire web page. Since they define the overall structure for the web page, they require other templates (partial and regular) to complete them. For isomorphic web applications, these types of templates are used to render the web page on the server side for the initial web page response, that is sent to the client. In the IGWEB project, we place layout templates in the shared/templates/layouts folder.
