You can style all form elements using CSS. A basic knowledge off CSS is helpful for that. 

Styling a form with CSS includes the following steps:

1. Create your own CSS and upload it to your PAS installation with the help of the File Manager.
   Go to page Styling Forms With CSS for more information on how to create your own CSS file based on a useful template.
2. Apply the uploaded CSS to your service.
3. Add your user defined classes to selected form elements.

Provide a CSS File

Create a CSS file that contains the styling definitions you want to apply, and upload it to the PAS system as a resource.
How to upload a CSS file resources is explained on Managing File Resources.

Apply the CSS File

Next, you need to apply the uploaded CSS file to your service.
