Which of the following is NOT a component of a Liferay theme?

In the context of Liferay themes, components like stylesheets, JavaScript files, and templates are essential elements that define the visual aspects and user interactions of a site.

Stylesheets are crucial for managing the design and layout of the application, allowing developers to customize the appearance according to their branding needs. JavaScript files enable dynamic features and interactivity within the theme, enhancing user experience through client-side scripting. Templates are used to structure the presentation of content, controlling how various content types are displayed in a consistent manner.

On the other hand, APIs (Application Programming Interfaces) are not a direct component of a Liferay theme. Instead, APIs serve as a means for different software components to communicate with each other, often in the realm of backend services or functionalities rather than affecting the front-end presentation directly. Thus, since APIs are not specific to the design or presentation layer of a Liferay theme, they are correctly identified as the option that does not belong to the components of a Liferay theme.
