TOPIC:

Is anyone using the interactive opinion page? I'm not connected via xApi.

In the xerte demo example page, the background of the slider bar is black, and the slider button is a different color. This is more useful as it looks like several discrete answers and not a progression along the slider. Does anyone know how to make the slider bar background black and the slider button a different color?

Also I don't understand the 'Classes' concept. The final graph that appears is a vertical bar, I can't make any sense of it.
THanks for suggestions.
