What are page fragments?

Page fragments are indeed reusable bits of content created with HTML, CSS, and JavaScript. They serve as modular components that can be inserted into various pages within a Liferay site, enabling developers and content creators to maintain consistency and efficiency in design. By using page fragments, one can easily update or modify content in a single location, which then propagates throughout the site where the fragments are utilized.

This approach allows for a more streamlined development process and enhances the user experience, as fragments can be tailored for responsiveness and interactivity, maintaining a cohesive look and feel across different pages. Furthermore, page fragments encourage reusability, making it simpler to create and maintain complex layouts by leveraging predefined code snippets.

The other options describe different concepts and features within Liferay but do not accurately encapsulate the function and purpose of page fragments. While template designs pertain to overall page structures, static content elements typically refer to non-interactive components. Custom application features are more complex and tailored components that do not necessarily align with the reusable and lightweight nature of page fragments.
