Padding around quiz

Hi,

I would like to remove the padding around my quiz within my LMS.  Currently, the embed code that I am using is as follows: 

<div><iframe frameborder="0" height="700px" scrolling="no" width="100%"></iframe>##:mediaresource guid="68947a24-f277-41fe-82ac-66e5b5b99e20" label="Knowledge Check" start="quiz_html5.html" method="iframe" title="quiz_content.zip"##</div>

I have attached images of what it looks like.  Is there any way to remove the padding or the way it spaces between content so it naturally flows within the lesson?
