What Are AEM Templates?

AEM templates define the structure of a page. They specify the layout, how components can be arranged, and what editable areas are available for content authors. Templates are crucial because they ensure uniformity and consistency across your website, allowing for a more streamlined and professional appearance.

Types of AEM Templates

AEM provides two primary types of templates:

1. Editable Templates: These are modern, flexible templates that allow content authors to modify layout and components within defined boundaries.
2. Static Templates: These are traditional, fixed templates that have a predetermined layout and components, offering less flexibility.

Building Web Pages in AEM

When building web pages in AEM, templates act as the starting point. A developer or content author selects a template that closely aligns with the desired end result and then populates it with components to add functionality and content. Therefore, choosing the right template is crucial, as it sets the stage for the web development process in AEM.

Customizing AEM Templates

While AEM’s standard templates offer a wide range of functionalities, there may be instances where you need to customize them for specific needs. This is generally done by developers who create a new template or modify an existing one to include special configurations or custom components.

Mastering AEM Templates

As you become more familiar with AEM, you’ll want to delve into advanced features and techniques related to templates, such as:

1. Template Versioning: Saving different versions of a template for rollback or auditing.
2. Conditional Logic: Implementing if-else logic to show or hide components based on specific conditions.
3. Responsive Design: Using templates that adapt to different screen sizes automatically.
