Thank you Derrick.
And thank you for your assistance with the responsive dashboard question. It works, I just need to figure out how to get the initial login login button screen to size visibly without negatively impacting the responsive settings (which allows it to expand from 0 to n) that work when the dashboard loads. (I use a simple <div id=mainViz></Viz> to embed it. Maybe the mainViz needs defined CSS added, but I digress.)
