Remove border and white space below form

Hi, 

I am embedding the form into my site, I am getting the outer border showing, I need to hide that from view so that it shows on a white background, also remove all the white space below the form, not sure how I can achieve this?

thanks, and look forward to hearing from you,

Ian Hadley 

For further inspections, could you please provide us the URL of the website that you have embedded your form into?

Waiting for your response.

Thanks.
