How can I reduce top padding of the form?

When I add the iframe form I my web site a appears with a 60px padding in the top.

How can I take it out? 

Hi,

To remove the padding you should add this code:

form.jotform-form {
    padding: 0;
}

Now, looking at your website, I presumed that you would like to not have the white background behind the jotform and if so, you can add this code instead:

form.jotform-form, .supernova {
    background: none repeat scroll 0 0%, none repeat scroll 0 0 transparent;
    padding: 0;
}

To add the CSS to your jotform please follow these steps: How to add CSS to my jotform.

Do let us know how it goes.

Best Regards,
Ben
