Form position on page

My rendered form is floating too high on the layout of its website page:
https://foodisfree.nz/donations/contributions/
I have added “

” to the form’s label to position the heading text low enough, but have had to disable the featured-image option as it overlapped with the header.

Is adjusting the css an option and where should I adjust it?

Thanks.
