How to remove the execessive white space on my site?

Hi I have build-out a detailed form using Jotform, using the embed code I have pasted the form in an Adobe Muse web page. Initially all was good the form sat nicely in the page after previewing & publishing.

I have made some changes to the form & copied the embed code again & pasted in to the web form page in Adobe Muse. I now have a huge amount of white space at the foot of my form with the Jotform footer banner.

I want to upgrade my client to a paid form facility, however they will not accept the ugly white space.

I have injected a variety of CSS code in an effort to remove the excessive white space but with no success at all.

Can you please advise how this white space can be removed & stay removed before I upgrade to a paid form.

Thank you, Jeff 

If you can access your web page source code, please edit the css file named "tenant-application.css" and locate the #u837841 ID. Now, replace the min-height value from 6609px; into a lower value like 1000px;.

Your embedded form is inside this div that set this height value inside the tenant-application.css file. Once you find that, changed its value and it should remove the excessive white space on your web site.

Let me know if you have any questions.

Thank you for the reply
However, I am not keen to play around with the actual source code for this issue.
I would like to know why each time I edit the form in Jotform that the embed code ( no matter which one I use) adds a huge amount of white space to my form when I embed in to Adobe Muse.
Is it a padding issue?? Is there CSS code that I can add to remove this huge white space as this is a really important form for my client.
My original form worked fine when I embedded it as cross all screen sizes, so my question is what has changed & how to fix it permanently please.
Many Thanks
Look forward to your prompt reply, many thanks

I inspected the webpage you provided and it seems that you were able to remove the blank space at the bottom of the form. 

Based on the reply from my colleague, the issue was related to the height of the div element of your webpage, not to the height of the form.
