Which component provides support for responsive design out of the box in AEM?

The component that provides support for responsive design out of the box in Adobe Experience Manager (AEM) is Layout Components. These components are specifically designed to allow developers and content authors to create layouts that adapt seamlessly to various screen sizes and devices. By using Layout Components, users can utilize predefined settings that ensure that content is organized in a manner that looks visually appealing and remains functional across different resolutions and devices.

Layout Components facilitate the creation of responsive web experiences without requiring extensive custom coding. They typically include features such as grid layouts and flexible containers that automatically adjust according to the viewport or the device being used. This functionality significantly enhances the usability of AEM in producing content that is accessible and visually consistent across platforms.

The other options, while they might relate to design, do not offer the same direct out-of-the-box support for responsive design as Layout Components do. The Responsive Style Guide, for instance, might provide guidelines for designing responsive elements but does not implement functionality itself. The Flexible Layout Manager is related to designing layout but lacks the comprehensive predefined solutions offered by Layout Components. The Adaptive Design Module can also assist in creating adaptive designs, but it does not operate as simply and effectively as utilizing dedicated Layout Components that are built into AEM.
