Overview
Components are pieces that enable users to create page layouts. We have a collection of curated components that fall into one of four categories, scaffolding components, structural components, full width components, and internal components.
Most components consist of two parts, a component data source which is an item that can be added and is visible in the tree view of the Sitecore Content Editor. A component data source stores textual content and imagery that will be displayed by a component rendering. A component rendering is an element that can be added to a page via placeholders using the Sitecore Experience Editor and connected to a data source.
