how can I eliminate vertical padding and space not being used (and producing a scroll-bar)?

Hi,

I think you are referring to the spacing around the form. To reduce the spacing, inject this CSS codes to your form.

.jotform-form{padding:0}

To do that,

1. Open the Form Designer

2. Go to the CSS tab

3. Paste that CSS code there.

You can also reduce the field question spacing, this will help eliminate the vertical scroll bar once your form fits perfectly on your screen. Here's how:

Go back to Design tab, click Line Layout and adjust the spacing.

Hope this helps!
