Does anyone have standard web form output from Podio responsively designed for mobile?

Podio created an app web form to embed in our webpage, however the website is responsively designed while the podio web form is not, causing it to look awful on mobile.

Podio does allow for CSS to be uploaded to fix the form, however I'm not sure how to style it based on podio's theme output. The form is living at https://podio.com/webforms/22442147/1581326

Does anyone happen to have a generic CSS style sheet I can upload and tweak to fit this form? Thank you!
