It is possible to change the color of the progresbar depending on its current value?
I have a simple progress bar that goes from 0 - 100, when the value is greater than 75, I want to change its color.
I guess CSS is your best bet. Change the class from within your code(or js) once you reached a threshold. Afaik you cannot do that with CSS alone.
If only the last part of the bar has to change it's color you may want to look into CSS gradients.
