Visual Editor allows you to select from a series of pre-built layout templates and edit the content in the live editor window.
On the Layouts tab, you can see the layout templates you can choose from. The number of layouts available is different for each tactic.
Web Channel reporting cannot differentiate between desktop and mobile impressions in Visual Editor-based campaigns. This works only for HTML campaigns.
Variables Editor
Variables editor is part of the Visual editor where you can customize layout elements. The Variables Editor tab lists the layout elements you can customize.
You can define the values (colors, images, size, etc.) of these variables for each element of a template on the Variables tab. For example, you can change the background color or size from one template to the next.
As you add the value to each variable, you can see the result immediately in the preview pane.
For all variables, the Reset button is available to revert the default template settings of the given variable.
Even if you have already done some content editing, feel free to switch to another layout template as all your existing edits will be retained in the new layout as well.
