Landing Pages are used for creating structured pages with columns and components like image navigation, tab panels, accordion sets, photo albums, etc. These pages may resemble newspaper or magazine pages more so than traditional word processing documents.
A Landing Page is assembled from sections, where each section is a row that contains one or more regions for content. Into each region you can place one or more content blocks. Some layouts are simple, providing two or more columns, while other regions provide special user interfaces, such as accordion sets, tab panels, and even headline (hero) banner support.
Important: At this time, you cannot place one layout inside of another layout, so it is not possible to create any truly nested layout structures.
