Are these forms mobile compliant?

Yes our forms are by default mobile responsive. You can see our guide for additional tips:

Some widgets might need additional css code to perfectly fit your requirements, but these are specific cases.

If you need further assistance please let us know.

Thanks for the response. I'm not seeing the same preferences window that's shown in the article you referenced, and there's no Responsive option in the the window I do see (see attached image). I've got a website in Muse (simplefinance.businesscatalyst.com) that has a job application form. Works great on the desktop, but in the tablet and phone versions the form will not display at all. Any help would be appreciated.

Sorry, here's a direct link to the various forms:

We have not yet updated the guide to show the new layout. You are currently on the new layout which you can access using the following URL:

If you need to go back to the old layout, just simply access https://www.jotform.com/?old.

The responsive option is not available in the new preferences layout so please do it in the designer instead.
