This article explains how to customize styles of forms.
Let your website's stylesheet do the work
Start with this option. Add the form to your website as-is without any customization. Often the main stylesheets of websites include settings to update the form automatically. In this case additional customization isn't required.
Customize styles in the form editor
If you need to customize styles you can do so from the form editor from the Styles navigation.
Use custom CSS
For advanced customization beyond what's possible from the visual editor, expert users can use custom form CSS. This option is restricted to administrators and technical users.
