The default Subpage is your basic page layout for most general-purpose interior pages of the website. This template is a two column layout and serves as your page default template.
Images placed in the content area of the page that you want to display at full width should be 760 pixels wide by a proportionate height. For the image to always span the full width of the content container you will add the class "responsive-image" to the image.
To create a new Page, navigate to CONTENT > PAGES > ADD NEW PAGE.
In the TEMPLATE field, select 'Subpage Default.'
Then add your content and set to live when you are ready.
