Ruby on Rails Layout

A layout defines the surroundings of an HTML page. It's the place to define a common look and feel of your final output. Layout files reside in app/views/layouts.
The process involves defining a layout template and then letting the controller know that it exists and to use it. First, let's create the template.
Add a new file called standard.html.erb to app/views/layouts. You let the controllers know what template to use by the name of the file, so following a same naming scheme is advised.

Example
