How to make this responsive?

Hi,

Unfortunately you cannot use CSS code to customize the form's Custom Thank You Message.

The styling of the Custom Thank You message is very limited due to restrictions on allowed code/scripts that can be used to customize it.

What I can suggest that you can actually do easier is to use Custom URL Thank You message.

User Guide: -Setting-Up-the-Thank-You-Page

You can then make your Thank You page mobile responsive. In fact, I think the custom Thank You page should be mobile responsive already if your website have the settings for it already.

Hope this help. Inform us if you need further assistance.

Thanks!
