Layouts allow pages to be rendered using a common structure without having to repeat code. Pages can share the same header, footer, menu, or sidebars. In Ruby on Rails, this is done by rendering a template, containing a fragment of HTML, inside of a layout. Learn to use the default layout and to create and use a new custom layout.
