4.5.WPPIZZA_WIDGET_CSS_CLASS
by default wppizza widgets have a classname of wppizza_widget
. As this is not referenced in the plugin itself, you could change that classname to something you might prefer.
To do so you can add the following to your wp-config.php
define('WPPIZZA_WIDGET_CSS_CLASS', 'some_classname');
somewhere before
/* That's all, stop editing! Happy blogging. */
where some_classname
is the classname you wish to set.
