I'm planning to develop the subject course for a millennial target population, and I'm an early 'boomer'.. It is being suggested to use a 'responsive design' HTML5 authoring tool to insure compatibility with mobile devices. My 'old guy' response is the screens are too small to support enough content, and may be difficult to work any navigation buttons other than a continuous scroll. Does anyone have any thoughts or opinions. Btw, is waiting for Q1 release of Responsive Design Storyline worth it?.
