Creating a Flexible Tumult Hype Document within a DIV with no set 'height'

Here is another post:

scale-height-only
scale-width-only

The sample document is called "autoheight".
After test, I found it will auto set both width and height in Hype preview or on wordpress site.

So, maybe it should called auto-width-height, auto-proportional, auto-flexible layout or ONE layout :grinning:?
