You can always host a contact form on your website and call it via http or https link from a banner.

Sorry it didn't work. It was worth a shot. One more for the roadmap it is.

You can't set the article to be responsive. Only the HTML that the article is displaying. In the case of HTML, think of the article as a frame or container for the HTML.Can you post screenshots of what your article looks like in each orientation? Are you saying that the HTML looks "sideways" when you rotate to landscape?

I honestly don't know whether or not you can disable the Done banner.What if you set it up as one tall page, disable scroll with CSS, and use anchor link buttons to navigate back and forth?
