How can I reduce the space below the header?

How can I reduce space below header on this form: https://www.jotform.com/build/82627014169154

Tried using margin & padding commands but didn't get it. Thanks. 

Looks like you have adjusted your header to move -100px towards the top. In turn, this caused the gap in between. Append these CSS code to your form to reduce that gap:

.form-header-group {

    margin-bottom: -50px !important;

    border-bottom: none !important;

}

I added another line to remove the bottom border of the header group to make it cleaner.

Awesome, thanks! looks like it worked!

Used -100px (for my own reference)
