In the Taxonomy section of your Article, click Categories > Verso Settings > Article Settings and choose the desired template type for your content. If no template is selected using the Verso Settings the article will default to the Two-Column template.

Single-Column 

This template is intended to be utilized for special, or long form, content experiences. It centers text on the page and only display mid-content ad units. The template also lends itself to relative less restrictive positioning options for media embeds including full-bleed image assets and nested image callouts. 

Two-Column 

This template is intended to be utilized for standard, or frequently produced, content experiences. It left-aligns text on the page and displays both mid-content and right rail ad units. The template is more restricted in its positioning options for media embeds due to the presence of a right rail ad unit. Therefore, full-bleed image assets and nested image callouts should not be used in this template.
