This example will allow you to add a CSS class called 'class_name' to the div surrounding your field.

Use this code if you have selected "Load Formidable Styling on every page of your site" in your Formidable Global Settings, but the Formidable stylesheet still isn't getting loaded.

If you would like to save the url of the site that the user came from, you can use this code. This will only work if you also go to the Formidable -> global settings page and turn on user tracking.
