- Module Class Suffix:
- A parameter than can be set in the Joomla Administrator that adds CSS code to a Joomla module in order to change its styling or display.
A Module Class Suffix allows website developers to change the look or layout of their pages on a module by module basis simply by creating a new class in their CSS file and then referencing it in the Module Manager. Some basic CSS knowledge is recommended, but this level of customization is suitable for most Joomla end users.
