How to make the 2D window extend to bottom of screen?

[mationai]

Want to extend the 2D window to the bottom of screen. Tried setting all height vars I see in TwoDView but nothing changes. Anyone can help?

The height is defined in .TwoDView in index.html. Leaving this open til someone knows about responsive height to bottom of screen or says that it's too much work to do so.
