TIP

Have you considered Edge Delivery Services for AEM?

You can continue using the methods described in this document for existing projects. However for new projects, Adobe recommends leveraging Edge Delivery Services.

In Adobe Experience Manager, components are the structural elements that constitute the content of the pages being authored. Components have always been a fundamental element of the AEM experience, making page creation simple but powerful for the author and the development of components flexible and extensible for the developer.

The Core Components are a set of standardized Web Content Management (WCM) components for AEM to speed up development time and reduce maintenance cost of your websites.

Features


Production-Ready	The Core Components are 30 robust WCM components that are well tested, widely used, and that perform well.

Versatile	The components represent generic concepts with which the authors can assemble nearly any layout.
Configurable	Template-level content policies define which features the page authors are allowed to use or not use.
Responsive	All Core Components are designed to be fully responsive, ensuring a seamless experience across devices

WebApp-Ready	The streamlined JSON output allows client-side rendering, still with a possibility of in-context editing.
AMP Support	The components have built-in support for the AMP standard, accelerating your mobile experiences.
Design Kit	A UI kit for Adobe XD allows designers to create wireframes that they can then style as needed.
Themeable	The components implement the Style System, and the markup follows BEM CSS conventions.
Customizable	Several patterns allow easy customization, from adjusting the HTML to advanced functionality reuse.
Versioning	The versioning policy ensures that the Core Components won’t break your site when improving things that might impact you.

NOTE

Core Components are not immediately available to authors, the development team must first integrate them to your environment. Once integrated, they may be made available and pre-configured via the template editor.

NOTE

Some versions of individual Core Components may only be compatible with certain versions of AEM.

See the individual help page (linked to in the previous list) for the specific component for compatibility information or reference the Core Components Versions document for more information.
