Allow users to view responsive course in landscape view only

It is possible to force landscape mode using CSS.

If you put this in the style tag in the index.html it will force landscape. This code is a test that I did, so it forces landscape on a desktop also.

#cpMainContainer { display:block; }

@media only screen and (orientation:portrait){

  #main_container { 

    height: 100vw;

    -webkit-transform: rotate(90deg);

    -moz-transform: rotate(90deg);

    -o-transform: rotate(90deg);

    -ms-transform: rotate(90deg);

    transform: rotate(90deg);

  }

}

@media only screen and (orientation:landscape){

  #main_container { 

     -webkit-transform: rotate(90deg);

     -moz-transform: rotate(90deg);

     -o-transform: rotate(90deg);

     -ms-transform: rotate(90deg);

     transform: rotate(90deg);

  }

}

If that IS the case, simply DO NOT create a responsive course.  A non-responsive course is by default a Landscape course (unless you deliberately set up the aspect ration of the stage area to be taller than it is wide).

You can set the content at publishing to scale to the width of the viewing area.
