Hypes transparent setting in the documents-panel will also remove the background-colors for the scenes. so all or none … @jonathan this may be worth a feature request.
in the meantime one possible solution would be to paste this to the head:
There’s no way to do a rotation lock in Mobile Safari. If you are embedding the page within a native app you could do this.
Theoretically you can “fake it” with code if you wanted; basically you would need to look at the screen.orientation property and listen to the orientationchange event. When you detect it is the way you don’t want presented, you could rotate a container div for the Hype document. If you are using flexible layout, afterwards you would probably need to call the HYPE.documents['yourDoc'].relayoutIfNecessary()API.
Thanks @jonathan , (bookmarked!) this is good to know as I advance in my skillset. Although it sounds simple enough it may likely be a bit beyond my very humble level of knowledge at this time For now I may have to just add the landscape layout.
If adding a landscape layout is too much of a work, you could just add text on landscape layout saying please turn to portrait. I won’t recommend it, but, if your app needs to be on portrait itself, this might be a workaround.
