How i can form responsive on tab width

To my understanding, the form on the website you provided isn't responsive in tablets, is that correct? 

I would like to apologize for I don't have an available tablet with me right now. I have checked the website and see that the form is embedded using its embed script.

<script type="text/javascript" src="https://form.jotform.me/jsform/63341678077463"></script>

May we suggest you try to embed your form using its iframe code instead and check if that will fix the issue you are having, please?

Otherwise, may we ask for more information/details of the issue you are having, please? You can also provide us a screenshot of the issue so we may try to reproduce it on our end.

We will wait for your response.

Thank you.
