#  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.

 ![convert forms custom css](https://www.tassos.gr/images/convert-forms-custom-css.png)

- Navigate to *Components > Convert Forms > Forms*
- Click *New* on the horizontal bar.
- Choose a form template or create a new one from scratch.
- Once you are in the Form Builder, click the **Advanced** accordion tab.
- You can fill in your Custom CSS as it is shown in the screenshot above.

 Using a Class Suffix is optional but recommended if you would like to combine your Custom CSS with your Class Suffix without having to edit your template's stylesheet.
