Form: format fields spaces and font

On page 1:  How can I reduce the space between the Header Properties and the text box?  

On Page 1 & 3:  I would like to change the font in the text box to the same as the description in the Header Properties.

I do not know how to css code, so I would need that provided.

To adjust the space between the header and the textbox, you can add these CSS code:

.form-header-group {
  margin-bottom: -40px!important;
}

You can change the font of your textbox by selecting the fonts located near the preview icon.

Hope this information helps.

Please let us know if you have further questions.

Thank you.
