You can customize the default button look by using these variables to add one or more CSS classes to them:

- `craue_formflow_wrapper_class` will apply for the wrapper div
- `craue_formflow_button_class_last` will apply either to the __next__ or __finish__ button
- `craue_formflow_button_class_finish` will specifically apply to the __finish__ button
- `craue_formflow_button_class_next` will specifically apply to the __next__ button

Default button (the one trigged by pressing the enter/return key) must be defined first.
Thus, all buttons are defined in reverse order and will be reversed again via CSS.
