Responsive container size with PDF fitting?

I've tried "sized container" and "in-line" mode, but in both I am unable to simulataneously have the PDF fully display, have no extra space in the container, and have it work on multiple screen sizes. Is there any way to have this work on multiple screen sizes?

The behavior in the demo https://documentcloud.adobe.com/view-sdk-demo/index.html#/view/IN_LINE/Bodea%20Brochure.pdf

does not match what happens in production with the code it says is being used; pdf remains 800px on smaller screensizes, exceeding the screen width.
