Predefined classes are aimed to be used for object stylization. This set of classes allows users to set or fully change the appearance of the object in WordPress Page Builder.
- Can be added or removed in the editor.
- Can be grouped in the editor.
- When you choose a class from the group it’s possible to setup whether the class will be added to an object or replaced with the already added class from this group.
