Would it be possible to use Font Awesome on JotForm?

What I'd like to do is create a thumbs up and thumbs down choice then depending on that choice the logic would send them different places. 

example: http://prntscr.com/ikhq0t

Yes, it'd be great to add colour fills and/or exterior colours to the icons. 

It is possible by using Custom CSS.

Here is a form demo I have created: https://form.jotform.com/80574970635970

This is the CSS I have Injected:

@import url("https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css");

#cid_3 .form-radio-item:nth-child(1):before {

  font-family: FontAwesome;

  content: '\f087';

}

#cid_3 .form-radio-item:nth-child(2):before {

  font-family: FontAwesome;

  content: '\f088';

}

You can clone the form and adjust it to your needs (colors, background colors, etc).
