• Module Class. A suffix applied to the CSS class of the Module. This allows you to create customized CSS styles that will apply just to this module. You would then modify the "template.css" file of your template to apply styling to this new class. Enter this parameter with a leading space to create a new CSS class for this module. Enter the parameter without a leading space to change the CSS class name for this module.
