What file format is generally used for Liferay theme configuration?

The generally used file format for Liferay theme configuration is theme.json. This file is essential in defining various metadata and settings for a Liferay theme, such as the theme's colors, styles, and other configuration parameters that determine how the theme behaves and appears in the Liferay platform. It allows developers to customize themes efficiently by providing a structured format for these settings.

While variables.scss is a valid file used in Liferay themes for managing style variables and applying SCSS styles, it does not serve as the primary configuration file for the overall theme settings. Instead, it focuses more on the styling aspect of the theme.

In contrast, style.css is the main stylesheet that contains the CSS rules for the theme but does not encompass broader configuration details. Similarly, theme.config, while it might suggest a configuration purpose, is not the standard file associated with Liferay theme settings.

Thus, theme.json is recognized as the key file format needed for Liferay theme configuration, supporting effective theme management within the Liferay framework.
