Zooming HTML5 Geogebra embedded in offline html5 page in an iframe
I'm working on a project where we are trying to produce GeoGebra interactions with some accessibility options. GeoGebra interactions are embedded in an iframe in static html5 page and work very well on most devices, even offline. We would like to implement a button, outside of the GeoGebra applet, that would zoom GeoGebra to available screen space (in a layer, popup window or whatever). Is there any example, tutorial, guidelines or something about zooming GeoGebra?
