Add Custom CSS
The Form Builder offers a way to inject your own Custom CSS with the option to also add your own Class Suffix.
- Go to Components → Convert Forms → Forms and click New.
- Choose a form template or create a new one from scratch.
- In the form builder, open the Design tab and expand the Advanced panel.
- Add your CSS rules in the Custom CSS option.
Optionally, add a Class Suffix (same panel) so you can target this form in your CSS without editing your template's stylesheet.
