Explanation/Reference:
The application skin provides a set of style formats for dynamic layouts.
These style formats use one of two basic layout types:
Inline-grid - allows you to set the number of fields (or other items) that appear on the row of the

dynamic layout.
Inline - allows you to add fields (or other items) in a row that flows "inline" like the words in a sentence.

You can choose from four style formats (plus a default format), derived from the two layout types, and you can add custom formats (for example, up to 6 columns in a grid): Default, Stacked, Inline Inline grid double, Inline grid triple References: https://pdn.pega.com/using-layouts-structure-content-sections
