What is HTL?
Formerly Known As
Updated: August 2016
HTML Template Language (also referred to as HTL) is Adobe Experience Manager’s preferred and recommended server-side template system for HTML. As in all HTML server-side templating systems, a HTL file defines the output sent to the browser by specifying the HTML itself, some basic presentation logic and variables to be evaluated at runtime.
In AEM 6.0 and 6.1 HTL was referred to as
Sightly. We are renaming it to “HTML Template Language” to clarify what the specification is for and to align with Adobe’s naming guidelines in general. This naming change takes place from August 2016 and applies to AEM version 6.0, 6.1, 6.2 and all versions going forward.
This naming change does not impact code or the API, therefore compatibility is not affected. For more information please to refer to the blog article on Experience Matters, that digs deeper into the renaming.
