Hello, I am having an issue where an embed code I am using is causing a ton of white space under the content of the code.

Here is the link to the website (embed code content is at the top): www.liberteegrounds.com/oktoberfest

Here is the original code: <embed src="https://mhme.nu/design/437b8989-f95d-433a-972e-fc1dbe24e8ad?embed=true" style="width: 100%; height: 100%;" />

^I changed this above code to the following so that the content would appear larger: <iframe width="890" height="700" src="https://mhme.nu/design/437b8989-f95d-433a-972e-fc1dbe24e8ad?" frameborder="0" allowfullscreen></iframe>

Even if i change the width and more imporantly, the height, there is still blank space that appears at the end. If i change the width and height both to 2000 then the blank space goes away on desktop but still appears on mobile. 

I've tried numerous CSS codes from other forums but still cannot figure this out.

I don't see any extra space.
Is the extra space only appearing in editing mode?
